So if you want to keep your eyes healthy and protected, be sure to add lutein and zeaxanthin to your diet! What are lutein and zeaxanthin, and what do they do for the eyes? Lutein and zeaxanthin are carotenoids that are found in high concentrations in the retina. They are believed to play a role in protecting the eye from damage caused by sunlight and other forms of radiation. Lutein and zeaxanthin also help to improve vision, especially in low-light conditions. Why should one protect their eyes from UV Light? UV radiation can cause various forms of eye damage, including cataracts, macular degeneration, and pterygium. Lutein is a natural pigment that helps to build a yellow layer in the eyes and protect them from the harmful effects of UV radiation. Zeaxanthin can help protect the the eye from macular degeneration? Macular degeneration is a leading cause of vision loss in the United States. Zeaxanthin can help protect the eye from this condition. Zeaxanthin is a pigment found in the retina, and it helps to filter out harmful blue light. This can help to reduce the risk of macular degeneration. How much should you be consuming each day? There is no set recommended daily intake for lutein and zeaxanthin, as research on the topic is ongoing. However, most experts recommend aiming for at least 10 mg of lutein and 2 mg of zeaxanthin each day. So if you want to keep your eyes healthy and protected, be sure to add lutein and zeaxanthin to your diet!

Date:
September 22, 2015 01:00 AM
Melatonin is a hormone secreted by the pineal glands. The circadian production of melatonin is tied to the day/night cycle. Light through the retina signals the pineal glands to suppress its production. Lack of light stimulation (at night) results to increased production of melatonin. The increased hormone production at night is associated with a good night’s sleep. According to a study, melatonin significantly reduces sleep latency and increases sleep efficiency. It has thus been used to treat insomnia.
Aging and Insomnia Insomnia is commonplace among the elderly. As we age, sleep problems which include difficulty in falling asleep and maintaining the sleep are so rampant. This is so because melatonin production declines with age. With age comes the disruption of the circadian rhythms associated with the production of melatonin. To this end, melatonin supplements come handy to the elderly in maintaining a good night’s sleep.
Aging and Alzheimer's Disease There is more to this hormone than a good night’s sleep and normal aging. There are evidences that melatonin suppresses Alzheimer’s disease. AD is the leading cause of dementia among individuals older than 65 years. Lack of sleep is a common symptom among AD patients and feels bad but sundowning (worsening of symptoms during evening hours) is worse. According to Netherlands Institute of Brain Research, the declining production of melatonin among the elderly not only affects the circadian rhythms but also enhances the development of Alzheimer.
Melatonin as an Antioxidant Melatonin production starts to decline at age 60. This is the onset of diseases like AD which leads to increased production of free radicals in the brain. According to a review paper written in 2000, there is a lot of pathological changes among AD patients’ autopsied brains as a result of free radical activity. Melatonin carries antioxidant properties which fight the free radicals and protect the brain neurons.
Melatonin Supplements Melatonin is a powerful hormone. Its function in sustaining optimal human health is crucial. New discoveries are being made on this versatile hormone. The fact that its production starts to decline at 60 only means that you need to use supplements and not fret over the onset of AD or insomnia. It is clear that besides being harmless and natural in treating insomnia, Melatonin is the most effective way of averting deleterious aging effects.

Vitamin A helps battle off contamination. It likewise serves to keep your skin smooth and supple. You can get a great deal of vitamin A from your sustenance - with liver meats being the best source. A few vegetables - carrots, broccoli leaves (the leaves, not the stems), sweet potatoes and kale, run a far off second, alongside spread. Dietary vitamin A hails from two sorts of sustenance: * Animal sustenance sources give "dynamic" manifestations of vitamin A - the form can use the vitamin promptly. They are called 'retinoid'. Retinoid are frequently utilized within skin creams and dermatological pharmaceuticals, as vitamin A is well known for its skin revival properties. * Plants give carotenoids (to illustration beta-carotene). Carotenoids are changed over by the constitution into vitamin A. Beta-carotene is the most widely recognized of the carotenoids. A brilliantly colored intensifies; this is the thing that gives carrots and sweet potatoes their orange shade. "Collaboration" is the point at which two or more substances join to make an impact more terrific than either could perform on its own. All supplements in the constitution have a synergistic impact, and vitamin A is no special case. Assuming that you as of recently have an iron inadequacy that brings about frailty - insufficient oxygen-transporting red platelets that abandons you ceaselessly tired a vitamin A insufficiency too will exacerbate it. Iron and vitamin A supplements taken together for frailty are more viable than either of these taken separately. When you don't have enough zinc in your eating methodology, the figure has a harder time proficiently utilizing vitamin A. The main sign of a vitamin A inadequacy is debilitated vision especially 'night blindness the powerlessness to see well in faint light. Vitamin An is utilized to structure the shades required in the retina for vision, and without enough A, your eyes can't do their employment. Keep in mind when your mother used to let you know to consume carrots so you could see well? There's truth in that old home cure.

What is the Main Source of Beta Carotene  Vitamins are essential ingredients for a healthy living. A good example of a very essential vitamin is Vitamin A, which consists of a group of fat-soluble retinoids, including retinol, retinal, retinyl esters [1-3] and retinoic acid. The main sources of vitamin A, retinoids, that comes from animal products and Beta carotene, which comes from plants are essential for not only treating deficiency syndromes but also boosting the immune system. What are the Importance of Vitamin A The most important type of vitamin A, is in no doubt beta carotene, a type of carotenoid. The main source of beta carotene is carrots. Carotenoids act as anti-oxidants and anti-inflamatory nutrients. Beta carotene is considered a safe vitamin A source because its sources are vegetables, for instance carrots, meaning that it is low in fat content. 1. Most animal products are rich in cholesterol. Once inside your body, cholesterol molecules bind together forming plaques which then attach themselves on the walls of blood vessels. This restricts the flow of blood resulting to high blood pressure. Plant products, unlike animal products, have less cholesterol and, vitamin A (such as beta carotene), keeps the cholesterol molecules in your body from binding together. It also prevents it from attaching itself on the walls of the arteries. 2. It facilitates normal growth of healthy cells and cell division. A normal replication of DNA requires presence of vitamin A. This vitamin, therefore, inhibits multiplication of cancerous cells and slows tumor growth down. Abnormal cell devision, as found in cancer victims, is a sign that there is deficiency of vitamin A. 3. Studies show that levels of vitamin A are very low for people suffering from viral diseases. When these people receive additional levels os the vitamin, they are said to recover faster since the defences are now restored. This shows that vitamin A is very important in causing retreats of viruses for instance those that cause measles, respiratory viruses, and even HIV. 4. Stroke victims, on the other hand, are encouraged to take vegetables and fruits (they are very good sources of beta carotene). The reason for this is because vitamin A in stroke patients helps reduce chances of the victim suffering from disabilities or in some extreme cases, death. 4. Apart from being very helpful in improving eyesight in dim light, beta carotene helps relieve the dry-eye disorder. When the lubrications of the eyes reduces, mainly due to reduction in tear production, the eyes can be very uncomfortable. Vitamin A eyedrops improve the cell fuctions in your eyes and restores their moistness. References.

Benefits of DHA
How Does DHA Improve Memory? DHA is an acronym for the words Docosahexaenoic acid. DHA is an omega-3 fatty acid that forms the main structural element of the testicles, sperm, the cerebral cortex and retina. The following foods are rich in DHA: herring, anchovies, fish roe or caviar, Bluefin, sardines, algae, swordfish, breast milk (instant milk formula as well). DHA is also manufactured from microalgae for commercial purposes. A study was conducted to find out whether DHA supplements can boost brain function in individuals experiencing age-related cognitive decline. It was established that DHA is effective in improving memory and learning. In this study, the subjects were administered with either 900mg per day DHA or placebo for a period of six months. Learning and memory tests were conducted before and after the study. Those who were administered with DHA demonstrated significant improvements in both learning and memory after the study was complete. In another study, DHA was administered to patients diagnosed with Alzheimer’s disease, but the patients did not record any significant change. It can therefore be concluded that DHA is most effective when used as a preventive measure. In the first study, subjects had mild cognitive disorders but showed remarkable improvement after being supplemented with DHA, unlike those in the second study. Conclusion Memory loss can have devastating effects on the patient and his family, but this can be avoided through proper nutrition and supplementation. DHA supplements ensure that there are sufficient amounts of this vital fat in our brain tissues to maintain normal brain function even as we age. A dose of 100mg everyday normalizes cell membrane stores of DHA over time. References:

LUTEIN Lutein is referred to as an antioxidant carotenoid which is simply a pigmented nutrient that is. How does Lutein helps the eyes. Lutein is responsible for the yellow colours found in fruits and vegetables. It is present in high quantities in leafy green vegetables such as kale, spinach, corn, orange juice, grapes, broccoli and yellow carrots and is dark in colour. Lutein is obtained by animals either directly or indirectly from plants and employed by them as an antioxidant and also for absorption of blue light. Each and every individual was born with a certain amount of lutein in your eye but it is not produced in the body. Where is lutein found in the body
The region of the retina responsible for central vision is called the macula. This area is sensitive to blue light and upon exposure to too much light can cause damage to the eyes. Lutein helps to protect this damage by filtering blue light before it can cause damage to the macula.
Also it is evident that lutein in food protects against cataracts as well as macular degeneration that are the common eye disorders. Lutein together with another carotenoid called zeaxanthin form the yellow pigment found in the retina and absorbs blue light that is a harmful component of the sunlight. Lutein is also may help protect carotid arteries found on the neck from clogging which is an indication of atherosclerosis that is a disease that leads to heart attacks.
Conclusion
If you do not eat properly, the amount of lutein in the eyes may deplete as you age. Your body doesn’t make lutein therefore it is recommended that you replace this through eating fruits and vegetables that are good sources of lutein. You can also get zeaxanthin in oranges, orange bell peppers, honeydew melon and also corn. Lutein and zeaxanthin works together and can also be found in egg yolks. Therefore to maintain that good vision always eat lots of fruits and vegetables and they will boost your vision.

It is a metabolite of canthaxanthin and zeazanthin which contains both ketone and hydroxyl fuctional groups. Astaxanthin is a lipid-soluble pigment and is colorful. The color of it is due to the extended chain of conjugated double bonds which is also responsible for the astaxanthin’s antioxidant function. It is found in feathers of some birds, yeast, trout, shrimp, crustaceans, crayfish, krill, salmon and micro algae. The red color of cooked shellfish and red color of salmon is due to the presence of astaxanthin.
How Astaxanthin Helps the Eyes?
When astaxanthin is combined with omega-3 fatty acids and Vitamin E then it helps the eyes to recover the watery condition and it lubricates it too. It helps the eyes to absorb Vitamin E by which it then nurtures and feeds the choroid and optical nerve which is behind the retina. This is the place where the blood vessel enters in to and leaves and this is the place where communication between retina and brain are established. The macula is protected by astaxanthin by its antioxidant activity and it also helps in eliminating the free radicals. It helps in reducing the risk of cataracts and AMD. It also helps in preventing the eyestrain and it also decreases its effects. The inflammation in the muscles of the eyes is decreased by it and it also improves the blood flow of the eyes.

It is normally seen as a yellow discoloration but there are times when a vegetable has so much lutein that it ends up having the color orange. Xantophyll where lutein is found was first thought to be a side effect of plants not having enough chlorophyll but further studies suggests that xantophyll has its own purpose and it is used to protect plants from the harsh blue light that comes from the sun. The sun releases a spectrum of light and among this entire light spectrum, the blue light has the most energy and it can damage the plants and it is the job of the xantophyll to absorb the blue light to prevent damage. What Does Lutein Do? When lutein is taken is ingested by a person, the lutein makes its way to the macula lutea of the eye. This is the main reason why the color of the macula is yellowish. The job of the macula is to absorb the blue and ultraviolet light that comes from the sun to prevent eye damage. When there is a lack of lutein, the macula is not able to absorb as much blue light which allows the blue light to reach the retina. This leads to damage on the retina which can lead to having impaired vision. Food Sources Of Lutein Lutein can be found in the most common fruits and vegetables that you find in the market today. One of the best sources of lutein is carrots which can only that what your parents said about carrots being good for your eyes are true. Other vegetables where lutein can be found include spinach, squash, corn, broccoli and other green vegetables. In fruits, lutein can be found from the citrus family and this includes oranges, grapefruit, lemons and some fruits from different families like peaches and papaya. There is one animal source of lutein and they are found in egg yolks. The only down side of egg yolks is the fact that it contains a lot of cholesterol which is bad for the body. Make sure you have enough lutein to protect the condition of your eyes.

With aging, our eyes and the associated muscles weaken. They can degenerate and lose our ability to see properly. Eyes enable us with vision to see the world, and losing the eyesight will halt affect our daily activities and movements. People are frequently worried about losing their sight, and try to find supplements that can prevent the loss of vision. However, this debility can be prevented. Supplements should be ideally be all natural, healthy, and with no side effects. Zeaxanthin is an important nutrient for eye health. This is found in found in green leafy vegetables, and also in other foods like eggs. Zeaxanthin fulfills most of the requirements that most people look in a supplement. WHAT IS ZEAXANTHIN Zeaxanthin and lutein are carotenoids that filter out the harmful high-energy wavelengths of light, and also act as antioxidants in the eye. This helps to maintain and protect healthy eye cells. Out of the six hundred carotenoids found in nature, only these two, Zeaxanthin and Lutein are deposited in high quantities in the retina (macula) of the eye. Unfortunately, our body does not synthesize the zeaxanthin and lutein it requires. This is the reason why green vegetables, eggs and other sources of these carotenoids are essential to proper nutrition. Daily intake of zeaxanthin and lutein through diet, beverages, fortified foods or nutritional supplements and is very important for the protection and continuation of good eye health. Studies have indicated that zeaxanthin and lutein can help to lessen the chance of chronic eye illnesses, including cataracts and age-related macular degeneration (AMD). Zeaxanthin, is also a bioflavonoid, that besides its benefits to ocular health, has been linked to providing many health benefits, including its anti-inflammatory property. Because of zeaxanthin being a carotenoid category bioflavonoid, its main action is over the blood vessels; it works by supporting the blood vessels around the retina area with their proper function. ZEAXANTHIN BENEFITS Zeaxanthin is both an anti-inflammatory phytochemical and an antioxidant; hence this has been used as a preventative measure for macular degeneration and cataracts. Its antioxidant properties keep eyes from being damaged from the harmful ultraviolet rays of the sunlight. Overall, zeaxanthin keeps the eye healthier, and looking younger. ZEAXANTHIN AGAINST CATARACT: Our natural eye collects and focuses light on the retina, and to properly provide this function continuously, the lens must remain clear throughout life. A major cause of cataracts is oxidation of the lens, which clouds it. Antioxidant nutrients, like zeaxanthin and lutein neutralize the free radicals or the unstable molecules associated with this oxidative stress associated with retinal damage. Thus, these phytochemicals play a role in cataract prevention. Higher dietary intakes of vitamin E, zeaxanthin and lutein can considerably reduce the risk of cataract formation. ZEAXANTHIN AGAINST AGE-RELATED MACULAR DEGENERATION (AMD): Zeaxanthin and lutein reduces the risk of AMD. In fact, studies like AREDS2 (Age-Related Eye Disease Study) are being conducted with supplements containing ten mg lutein along with two mg zeaxanthin each day, how it affects or lowers the chance of developing this degeneration. FOOD SOURCES OF ZEAXANTHIN Zeaxanthin is naturally found in some green leafy vegetables like kale and spinach. Other sources of zeaxanthin include egg yolk, yellow squash and bell-peppers. This makes zeaxanthin available as a completely natural nutrient, with no side effects.

Lutein from the Latin meaning of yellow, luteus, is a xanthophyll and is a naturally-occurring carotenoid. It is abundant in leafy vegetables which are green in color like spinach and kale. Lutein can also be found in egg yolks and is also present in plants as a fatty-acid tester and most of all, it can be found in the retina and concentrated in the macula, which is a small area of the retina mainly responsible for central vision. This helps the eyes to be protected from oxidative stress and blue light photons with high energy. Eye Health
Several studies have found that an increase in macula pigmentation helps decreases the risk for eye diseases and one of them is Age-related Macular Degeneration(AMD). Some concluded that visual activity is improved with lutein supplementation alone or lutein together with other nutrients. Other studies also show that AMD seemed to be directly related to having low carotenoids in the body. It does follow in this It commonly follows that this daily attention to the diet to get all the required lutein for our body is where supplementation suggestion comes in since many are not able to do so especially for people around the age group of 70 and up where the attention needed is just too taxing. And since failure to have sufficient lutein is not acceptable for these people with a high risk of AMD or those already with AMD but hopes to slow it down or even stop the progression of the decease, supplementation is a viable and reliable way to assure sufficient lutein intake. This would eventually lead to increases in blood serum levels that would be equal to a diet sufficient of high lutein foods. However it’s worthy to note that risk reduction does not equate to a cure because once macular degeneration has started there is no way to reverse it. But reduction of risk may be an implication of prevention for some people. Further research needs to be done. However in terms of prevention before the decease starts, results have been promising.

Night blindness is very common nowadays. According to statistics, a lack of vitamin A is the primary cause of night blindness or inability to see at night or in dim light. The treatment of this eye condition will depend upon the cause. Treatment may be as simple as getting a new eye glasses prescription. But invasive procedures may also be required most especially those that are caused by cataracts. Fortunately, Bilberry extracts may help night blindness. Bilberry is a low – growing perrenial shrub growing approximately 15 to 20 inches in height. It is a member of the family Ericaceae in the genus Vaccinium. Its branches are green with sharp edges. It bears edible berr that is seemingly wrinkled and black. Bilberry is a comparative to the common berries known as blueberry and cranberry. The active compounds in bilberry fruit are known as anthocyanosides. Bilberry extract has a deep bluish purple tone which contains the majority of the active substance of the fruit known as anthocyanidin. Anthocyanidin is a component of anthocyanosides. It can help increase the formation of rhodopsin. According to studies, rhodopsin is formed from an aldehyde form of vitamin A called retinaldehyde, or retinal as commonly used. It is then bound to the protein opsin. This compound consisting of retinal and opsin is stored in photoreceptors of the retina of the eye known as rods and cones. Rhodopsin is the compound in the eye that is responsible for adjusting eye perception to light variations. This plant extract is also commonly used for treating eye problems like cataracts and retinal disorders particularly retinopathy. Scientists found out that anthocyanosides help protect the retina. Since bilberry improves the formation of rhodopsin, adequate levels of rhodopsin can significantly improve night vision and reduce visual fatigue. This eye pigment could help those individuals who are having trouble driving at night because of its rhodopsin regenerating property. Aside from supporting a healthy eye function, bilberry has many other health benefits. It has an antioxidant, anti – inflammatory, collagen stabilizing and vasoprotective properties. Generally, anthocyanosides are considerably beneficial to the overall health of the body. It can improve circulation by preventing blood clumping by reducing platelet aggregation. It can also prevent or reduce the amount and extent of damage to cells caused by free radicals. Further clinical studies are being done to be able to get concrete evidence on the fruit’s benefits especially to the eyes. Preliminary results show that bilberry decreases eyestrain after an excessive use of computers, protects against glaucoma by improving blood vessel integrity in the eyes, reduces the occurrence of cataracts by maintaining the integrity of connective tissues in the eyes and lessens the risk of retinopathy among diabetic patients. Preparations of bilberry extracts include teas, capsules or tablets.

Date:
December 17, 2010 10:48 AM
Hyaluronic AcidDiscovered in 1934, hyaluronic acid can be found anywhere there is the need for connective tissue in your body. Your joints, your eyes and your heart all contain hyaluronic acid, and a shortage can lead to a wide range of bodily defects, including the appearance of accelerated aging. It is a glycosaminoglycan, a form of polysaccharide that is not only found in connective tissue and epithelial and neural cells, but is also important in the growth and renewal of body cells.
Hyaluronic Acid and Your Joints The highest concentrations of hyaluronic acid (HA) in your body is found in the synovial fluid, the fluid lubricating contained in your joints, and it is also plays an important role in maintaining the function of cartilage in keeping your joints flexible and well cushioned. It is chemically a glycosaminoglycan that is formed from glucosamine and glucuronic acid. Its production is boosted by chondroitin, which is why glucosamine and chondroitin are commonly used supplements for the treatment of arthritis. Specifically, HA joins with collagen and elastin to produce cartilage, and also increases the supply of synovial fluid that maintains lubricity within the joints. Without the synovial fluid your cartilage would soon become worn away and your bones would grind together, eventually seizing up. By taking hyaluronic acid orally as a supplement, you can help to maintain healthy joints by maintaining the integrity of the cartilage and the quality of the synovial fluid. Because the cartilage contains no blood vessels, it is reliant on the synovial fluid to keep it supplied with nutrients, and specifically with HA which is a large part of its structure. Without this important polysaccharide your body would not be able to function: no mobility, dry flaky skin and poor or no eyesight. Hyaluronic Acid and Your Skin Hyaluronic acid occurs in the lower layers of your skin where it helps to maintain a smooth and full appearance to your skin due to its hygroscopic nature in absorbing up to a thousand times its weight of water. For this reason HA is frequently used in skin moisturizing treatments and lotions. HA is not found inside body cells, but appears to be restricted to the extracellular regions between cells where its moisturizing properties are critical in maintaining suppleness. Elastin requires copious quantities of water to remain elastic or it would otherwise become brittle: that is why our skin looks dry and wrinkled when we age. It is due to a lack of moisture: the moisture that hyaluronic acid can bring to the table. The problem is that HA reduces with age and in order to maintain our youthful looks we have to take a supplement. Hyaluronic acid doesn't last long in your skin: it has to be renewed constantly and each day about 50% of the HA content of your skin is lost. It takes about two weeks for the same degree of loss to occur in the synovial fluid of your joints. The look of your skin depends to a very large extent on the extracellular matrix, or what is contained between your skin cells. The more moisture there then the smoother and plumper your skin will appear. As you age, your hyaluronic acid production drops and so your skin becomes increasingly more depleted of moisture. This causes it to dry up and wrinkle. Were there one substance that I would choose as the elixir of life it would be HA, because by taking a regular supplement your natural daily loss is replenished and your skin is given a hand to maintain its soft, moist plumpish look that helps you to keep you looking young. Hyaluronic Acid and Your Eyes The vitreous humor is the liquid inside your eyeball, and it contains a large amount of hyaluronic acid. It helps absorb shock and to maintain the shape of the eyeball. The HA is so important that your body has developed a special set of cells known as the hyalocytes of Balazs that are believed to promote the renewal of hyaluronic acid, and also possibly its breakdown. There is still a lot of research going on into this but the importance of HA in the vitreous humor and other aqueous area of your body is not in question. It helps to retain water and give structure to the liquid media within your body, whether that is between the bones of your joints, in the dermal and epidermal regions of your skin to keep it supple, or in your eyeball. In fact, it is believed to take up 70% - 80% of your eye, and helps to keep the retina in place exactly where it has to be for your eyesight to work.
a) present between the cells in every tissues in your body, and b) a consumable, in that it gets used up rapidly, and c) your biochemistry's ability to regenerate it reduces with age, a supplement is the ideal way in which to maintain its levels in your extracellular system. In some instances injections are given, particularly in expensive anti-wrinkling treatment, but studies have shown that hyaluronic acid baxyl taken as an oral supplement shows an improvement after an average of 3 months treatment. It should be understood that the average person has around 15 grams hyaluronic acid in their body, of which 5 grams is continually degraded and synthesized daily. When you reach an age that your ability to generate HA is impaired, then an oral supplement will be less expensive than injections, the hyaluronic acid of which will also be degraded with time. It won't be long before you need more treatment, and oral supplements are less expensive than private hypodermic injections. A Hyaluronic acid supplement baxyl can be taken to improve the suppleness and appearance of youthful skin, help maintain the integrity of your eyesight and help to reduce the symptoms of arthritis and many other conditions brought on by a reduction in the synovial fluid and hydration of the skeletal and connective tissues of your body. In other words, it helps to keep you looking younger for longer and to keep your joints and your eyesight in good health. Have you had your daily dose of hyaluronic acid today?Baxyl is a liquid form of hyaluronic acid that is easy to take and easily assimilated into the body because its a liquid.

December 10, 2010 06:11 PM
Lycopene
Lycopene is a tetraterpene carotene that is largely responsible for the red color of tomatoes and other fruits and vegetables such as carrots and papayas, although it is not a form of Vitamin A as other carotenes are. It is responsible for the production of the pigment beta-carotene which does have Vitamin A activity, and that is also found in carrots and similarly colored foodstuffs. The health benefits of lycopene have been studied in relation to its possible antioxidant activity and its effect on atherosclerosis and other conditions of the cardiovascular system, and also in its potential anti-cancer properties. Although these properties are still under investigation, there is traditional and anecdotal evidence that is can be used to ward of cancer, heart disease and macular degeneration, a degenerative condition of the retina that results in loss of central vision. It can be taken as a supplement as a form of insurance, even though the firm medical evidence for its use has yet to be established. While not claiming this to be the case with lycopene, many such traditional uses have eventually been proved to have a firm foundation in science, and many of the initial results and studies with lycopene are tending that way.
The Antioxidant Properties of LycopeneCarotenoids tend to possess antioxidant properties, and lycopene is as much a carotenoid as the powerfully antioxidant beta-carotene. The problem is that studies focusing specifically on lycopene are rare, and that while such properties can be assumed by association, they have not been conclusively proved for lycopene. Nevertheless, the health benefits of tomatoes are largely assumed to be due to their high lycopene content, particularly powerful when cooked.
These studies have been inconclusive, although everything is pointing toward lycopene being a powerful antioxidant displaying all the properties of Vitamin A and perhaps more. A lycopene supplement is believed to be safer than Vitamin A which can be toxic in large quantities (300,000UI +), and lycopene is used as an approved food coloring. Have you had your Lycopene today?

May 09, 2010 08:20 AM
Although Vitamin A deficiency is prevalent throughout the world, retinol toxicity is a common occurrence as well. About five percent of those who supplement with vitamin A unknowingly suffer from toxicity symptoms. It should be noted that supplementation at 5,000 to 10,000 IU per day of preformed vitamin A, which is dose that is well within the range that is offered in many popular vitamin supplements is a safe effective doses, additional supplementation of vitamin A may actually lead to a cumulative toxic overdose. Additionally, accidental ingestion of one single, large dose of vitamin A, can produce acute toxicity in children, always keep vitamin A out of reach of small ones. A large study on over 22,000 pregnant women who supplemented with vitamin A during early pregnancy found that those women taking more than 60,000 IU of preformed vitamin A per day in the form of supplements had about one in fifty-seven of a chance of a malformation attributable to the supplement. In consuming more than 60,000 IU of vitamin A, a five-fold greater risk for birth defects arises as compared to consumption of less than 25,000 IU per day. The prevalence of birth defects seems to be greatest in those women who consume high levels of pre-formed vitamin within the first seven weeks of their pregnancy. Authors of the study concluded that women who may possibly become pregnant should limit their retinol intake to below 15,000 IU, or supplement with beta-carotene instead. Beta-carotene is the orange/yellow-colored pigment that is often found in many garden vegetables. It is a retinal precursor. The body is able to easily convert beta-carotene into vitamin A by turning the carotene molecule into two molecules of retinol as they are needed. This allows for the avoidance of toxic accumulation of pre-formed vitamin A. Once beta-carotene is transformed into active retinol, it offers the same beneficial affects. The only symptoms associated with beta-carotene supplementation are loose stools or slight discoloration of the skin. This makes beta-carotene, even at high doses, safe for the body because it does not exhibit toxicity. An added benefit of beta-carotene is that it is a much more potent antioxidant than retinol, as it provides even greater protection against oxidative challenges. The worst thing that can happen to you if you take too much beta-carotene is that you may turn orange like a carrot. However, this should not be a worry because you will be just fine. The majority of nutrients that are used in supplementation have a large measure of safety. Unfortunately, the use of vitamin A warrants prudence and caution. This is especially crucial when it is consumed by children or those women who are pregnant. Because of this, the level of vitamin A in excess of the upper limit of intake that is prescribed by the Food and Nutrition Board of the Institute of Medicine, is a crucial criterion in determining how good a product is. The criterion for potential toxicities asks whether the nutritional supplement contains vitamin A. If so, it asks whether the potency of vitamin A exceeds 100% of the upper limit of intake that is prescribed by the US Food and Nutrition Board. To be on the safe side, take beta-carotene which has no side effects even at very high doses but exhibits the same health benefits of consuming preformed vitamin A. Look to your local or internet vitamin store for name brands like Solaray and Source Naturals for all your Vitamin A and beta-carotene needs.

The ability of ginkgo to boost brain function has been studied extensively. Most importantly, ginkgo increases oxygen supply to brain cells, as the brain is the body’s most sensitive organ to oxygen deprivation. Additionally, ginkgo has been used to improve electrical transmission in nerves and supply more oxygen and nutrients to brain cells. The effect that ginkgo has on the brain and circulatory system disorders seems to be extremely promising for a variety of conditions. Ginkgo extract has also helped dementia that results from poor blood flow to the brain. Senile dementia is often recognized by depression, unusual fatigue, and memory problems. Ginkgo has the ability to help improve circulation to the brain tissue, which in turn improves brain function. Blood platelet aggregation, or clotting, can cause serious problems in the body. Among these are strokes, heart attacks, and coronary thrombosis. It has been found that ginkgo can reduce the tendency for platelets to stick together and prevent them from forming clots in the arteries and veins.
The brain and nervous system are extremely sensitive to free-radical damage because of the high percentage of unsaturated fatty acids. It has been found that ginkgo’s antioxidant activity is particularly powerful in these areas, along with the eye and retina. The leaves of the ginkgo plant are used to provide adaptogen, alterative, antioxidant, antiseptic, and stimulant properties. Primarily, ginkgo is extremely helpful in treating ADHD, Alzheimer’s disease, lack of attention span, blood clots, cardiovascular disorders, poor circulation, dementia, dizziness, edema, impotence, inflammation, ischemia, memory loss, lack of mental clarity, multiple sclerosis, muscular degeneration, PMS, Raynaud’s disease, senility, stress, stroke, and tinnitus. Additionally, this herb is very helpful in dealing with allergies, angina, anxiety, arthritis, asthma, cancer, carpal tunnel syndrome, coughs, depression, lack of equilibrium, eye problems, hearing problems, hemorrhoids, lung disorders, migraines, mood swings, toxic shock syndrome, transplant rejection, varicose veins, vascular problems, and vertigo.

Date:
December 01, 2008 10:03 AM
Hyaluronic acid, also known as hyaluronan, is one of the main components of the extracellular matrix of connective tissue and joints, and is one of the main chemicals contained in the synovial fluid that lubricates your joints. Before we discuss how it can be used to help restore the function of damaged joints, let's have a look at what causes joint pain, and why joints can break down long before their time. You might have heard that arthritis is an inflammatory condition, or that it is due to the immune system. This is true to an extent, and rheumatoid arthritis is an immune system problem, although osteoarthritis is a different problem altogether. Arthritis is not the only cause of joint pain of course, but is by far the most common cause. As already inferred, there are two forms of arthritis, each with a different basic cause. Osteoarthritis is the most common form of joint disease, and is largely due to wear and tear, injury or can be hereditary. However it is usually initiated by damage, the joint surface becomes roughened and the bone around the damaged area gets thicker to compensate. A joint is where two bones meet, and not all joints move. You have the fixed joints in your skull, for example, and those between the ribs and the spine. However, arthritis generally affects the joints associated with movement, mainly the knees, hips, fingers, toes and elbows. The ends of the bones are covered with a thin layer of cartilage, which can absorb shocks and both cushion the joint and allow the ends of the bones to move smoothly over each other. Round each joint is a membrane known as the synovium that is filled with the thick synovial fluid, which lubricates the cartilage. The bone ligaments hold them close to the joint, and prevent them moving too much and dislocating. Finally, the joint is completed by the tendons that attach the muscles to the bones they control. Osteoarthritis causes a joint to deteriorate: the cartilage becomes rougher and wears, and the bone beneath the cartilage gets thicker. At the edge of the joint the bone tends to grow outwards, forming spurs and the synovium swells producing extra synovial fluid. This causes swelling and pain, and ultimately the joint can be damaged beyond repair. This process takes a number of years to reach a stage whereby pain and discomfort are felt. Before that situation occurs, however, the joint tries to repair itself, and hyaluronic acid can take part in this process. It is mainly involved in the reparation of connective tissues such as cartilage, although there are other connective tissues which hyaluronan has been found to repair. These include skin, eyes and heart valves and hyaluronic acid can arguably be used to help repair all of them. However, it is joint tissue with which we are concerned here, and hyaluronan is an important component of articular cartilage: the type of cartilage involved in movement (knees, hips, etc), as opposed the type that forms your nose or the external part of your ears. It is believed that injections of hyaluronic acid can help to repair damaged articular cartilage. However, osteoarthritis is only one of the two forms of arthritis. The other is rheumatoid arthritis, and this is much more sinister. Rheumatoid arthritis is caused by the attack of your joints by your own immune system, although why this happens is unknown. The most likely theory is that certain infections trigger the immune system, and it then proceeds to attack the synovial joints. Cytokines are responsible for inflammation of the synovial fluid, which can also cause fever, loss of weight and appetite, and inflammation of the blood vessels. The body tries to generate more synovial fluid which causes swelling round the whole joint, putting pressure on the damaged areas, and generating even more pain. The inflammatory response commences and the whole area becomes seriously painful. The smaller joints are most commonly affected, such as the fingers and toes, but it can progress to the elbows, hips and the knees. The joints become red, swollen and finally too stiff to be used. The sinusitis eventually leads erosion of the joint and deformation. Because hyaluronic acid behaves like the synovial fluid, it is believed that it can be used to treat both forms of arthritis. It is a glycosaminoglycan, an unbranched polysaccharide of the same type as chondroitin sulfate that is commonly used to treat arthritis. It can be used to increase the viscosity of the synovial fluid, and render a more effective lubricant. However, it is in treatment of osteoarthritis that hyaluronan is most likely to find success. It is used to improve the viscosity of the synovial fluid, so providing increased lubrication to the joint and helping reduce the pain. In fact it not escaped notice that those who eat a diet rich in hyaluronic acid tend to live longer and look younger than those that do not do so. Commercial preparations are currently in use or under evaluation for disorders such as glaucoma, fractures, and detached retinas, damage to cartilage, healing ligaments and osteoarthritis. These last three are particularly of interest to arthritis sufferers, and signs are that they are effective with many cases. However, it has also been established that smoking cigarettes can negate the effect of hyaluronic acid, and excessive levels of Vitamin C can also degrade it. Estrogen treatment, however, can enhance its effect in repairing connective tissue. Zinc deficiencies have also been found to have negative results, so make sure that these factors are addressed if you are using hyaluronic acid to treat arthritis. Something to keep in mind if you are taking hyaluronic acid orally is the size of the molecule. It is a very large molecule, and suffers from the same absorption problems as chondroitin sulfate. There are smaller hyaluronan molecule versions available if you can find them, that improve the absorption through the intestine, but if not then the dose will generally be greater than expected due to the low absorption levels due to the molecule being too large to be easily absorbed through the tissues into the bloodstream.

Maintains Healthy Visual Function* It has been well established that lutein is present in high concentrations in the retinal tissue of the human eye. However, a study was conducted in human volunteers to determine whether taking lutein in supplement form actually increased the density of the carotenoid pigments present in the macula. In this study of eight individuals, researchers estimated the density of the macular pigments prior to having each individual take 10 mg of lutein daily in supplement form for 12 weeks. Plasma lutein concentrations were measured at 4-week intervals. During the first four weeks of the study, plasma levels increased five-fold from pre-supplement measures, and then remained at this level for the duration of the study. It was also shown that, due to increased deposition of lutein in optical tissues, macular pigment density increased by an average of 5.3% at the 4-week mark, and continued to increase until the duration of the study.1 A study was also conducted to investigate the possible role of specific nutrients in protecting the lens of the eye against aging, a risk factor for compromised visual function. The study was comprised of 376 individuals aged from 18 to 75. Of the nutrients measured, it was found that the lenses of individuals with higher concentrations of lutein and zeaxanthin showed less of an effect from the aging process. The investigators concluded that these carotenoids might play a protective role in supporting the maintenance of healthy vision.2 The Age-Related Eye Disease Study (AREDS) was a landmark study of the effects of diet and antioxidant supplementation on eye health. The study enrolled over 3500 subjects aged 55 to 80 years who were followed for approximately 6 years. Among the data collected in this multi-faceted study was a self-administered Food Frequency Questionnaire (FFQ). The AREDS Report No. 22 examined the data from the FFQs and determined that, of the nutrients evaluated, only lutein and zeaxanthin were directly related to maintaining eye health with statistical significance3. These findings corroborated similar results of an earlier multi-center study published in the Journal of the American Medical Association that also found that those with a higher intake of lutein and zeaxanthin maintained healthier eye function.4 These promising results have spurred the design of a second major clinical trial (AREDS2), which is currently enrolling participants to study the impact of supplemental xanthophylls (FloraGLO® Lutein and zeaxanthin) and other nutrients on age-related eye health.5 In addition, a double-blind placebo controlled trial was performed in ninety individuals who had signs of compromised visual function. Individuals were divided into three groups and received either 10 mg FloraGLO® lutein, 10 mg FloraGLO® lutein plus a multivitamin/multimineral formulation, or placebo for 12 months. In both the FloraGLO® lutein and FloraGLO® lutein plus other nutrients groups, improvements were seen in mean eye macular pigment optical density, visual acuity and contrast sensitivity. No improvements were noted in the placebo group.6 These results demonstrate FloraGLO® lutein’s beneficial effect on maintaining healthy visual function. Newly published research has demonstrated that lutein and zeaxanthin supplementation may enhance visual performance under glare conditions. Forty healthy subjects took daily doses of 10 mg FloraGLO® Lutein plus 2 mg zeaxanthin for six months. They were evaluated for changes in macular pigment, glare disability and photostress recovery at the onset of the study, and at 1, 2, 4 and six months. After six months, subjects experienced an average increase in macular pigment optical density (MPOD) of 39% compared to baseline, and all but two participants experienced some increase in MPOD. This increase in MPOD was also directly related to measured improvements in visual performance after exposure to bright light, as well as photostress recovery.7 This study suggests another way in which lutein and zeaxanthin can help support optimal visual function in healthy individuals. Potent Antioxidant Protection* Most of the beneficial effects of lutein are ascribed to its potent free radical scavenging abilities. It is well-known that lutein is a carotenoid related to beta-carotene and possesses antioxidant activity against a number of reactive oxygen species.8 More direct evidence for the free radical scavenging activity of lutein is found in studies of its effects on human lens epithelial cells. Cell cultures were exposed to ultraviolet light after pretreatment with lutein or alpha-tocopherol. Both nutrients were found to reduce ultraviolet-induced damage to lens epithelial cells. However, lutein was shown to have significantly higher photoprotective activity than alpha-tocopherol9 demonstrating its potential as a high-powered antioxidant. A further review of the mechanisms of lutein in conferring a protective role reveals evidence for its antioxidant activity in various body tissues. Lutein has been shown to be an effective antioxidant in vitro as well as in experimental models of a number of body systems.10 Supports Healthy Skin* A recent randomized, double blind, placebo-controlled study has demonstrated the positive effects of oral and topical administration of lutein on skin health parameters (surface lipids, hydration, photoprotective activity, skin elasticity and skin lipid peroxidation). Forty female subjects were divided into four treatment groups. Treatment options included oral administration of 5 mg of FloraGLO® Lutein twice daily or placebo and topical administration of 50 ppm FloraGLO® Lutein twice daily or placebo. Each treatment group received either an active oral treatment with a placebo topical treatment, a placebo oral treatment with an active topical treatment, both active treatments, or both placebo treatments. Statistically significant improvements were seen in all five parameters tested in all treatment groups compared to the group receiving only placebos. The greatest overall improvements were seen in the group receiving both active oral and topical treatments, while lesser but still significant improvement was seen in both the active oral only and the active topical only groups. Additionally, oral administration of lutein conferred superior photoprotective activity (as measured by skin surface redness after exposure to ultraviolet light) and prevention of lipid peroxidation (as indicated by levels of malondialdehyde in skin lipids after exposure to ultraviolet light) than either topical lutein or placebo.11 Diverse Cinical Benefits* Evidence from various experimental trials suggests that lutein may play a protective role on the circulatory and cardiovascular systems. Its antioxidant activity may also extend to the heart, skin, lungs and blood vessels, making it a nutrient with diverse clinical benefits. Lutein possesses the ability to promote the health of many body tissues.12 Suggested Adult Use: One softgel daily with food, or as directed by a health care professional.

DHA is the most abundant essential fatty acid (polyunsaturated fatty acids) found in the brain and retina. DHA is essential for the proper functioning of our brains as adults, and for the development of our nervous system and visual abilities during the first 6 months of life. DHA is found in cold water fatty fish, including salmon, tuna (blue fin tuna have up to five times more DHA than other types of tuna), mackerel, sardines, shellfish, and herring. Lets take a look at what DHA can do for you. DHA makes infant formulas more like human milk than "conventional" formula containing Alpha-linolenic acid and linoleic acid, which are precursors to DHA. It has been an ingredient in several brands of premium infant formula sold in North America since 2001. Mead Johnson was the first infant formula manufacturer to add DHA and ARA (arachidonic acid) to its Enfamil Lipil product, several other manufacturers have followed. DHA levels in breast milk are higher if a mother's diet is high in fish. DHA is also present normally in very high concentrations in the retina. DHA supplementation would be particularly important for mothers who have consumed excessive alcohol, because alcohol inhibits the desaturase enzymes necessary for DHA synthesis. Docosahexaenoic Acid (DHA) is a type of Omega-3 fatty acid, a nutrient that has been studied for its role in heart, brain and eye health. An experiment that studied the individual effects of EPA and DHA found that EPA reduced natural killer (NK) cell activity and cell-mediated immune response, but that DHA does not so this study concluded that the immune-suppressing effects of fish oil are mainly due to EPA, not DHA. Omega-3 fatty acids found in fish oil help lower triglycerides (fats in the blood), lower blood pressure, reduce the risk of blood clots, improve the health of arteries and reduce the amount of arterial plaque (which narrows arteries and causes heart disease). Many people believe that excessively high omega-6 rather than omega-3 in the modern diet is responsible for an increase in allergies and the need to take aspirin to reduce the risk of heart attack (myocardial infarction). Sunflower, safflower and corn oil are particularly rich sources of linoleic acid, which is at the root of the omega-6 fatty-acid family. The ability of enzymes to produce the omega-6 and omega-3 family of products of linoleic and alpha-linolenic acid declines with age this is why we need more omega 3 DHA in our diets. In fact, a high omega-3 fatty acid diet increases the alpha-tocopherol content of heart muscle membranes by five times, and this effect is most prominently associated with DHA because the heart muscle prefers DHA as its raw materials to manufacture and strengthen its membranes. Dietary DHA may reduce the risk of heart disease by reducing the level of blood triglycerides in humans. Low levels of DHA result in reduction of brain serotonin levels and have been associated with ADHD, Alzheimer's disease, and depression, among other diseases, and there is mounting evidence that DHA supplementation may be effective in combating inflammatory bowel disease as well. Dietary changes in the past century have lowered the consumption of omega-3 to a state of subclinical deficiency that is epidemiologically related to cardiovascular disease, inflammatory disorders, mental and psychiatric diseases and suboptimal neurodevelopment. Decreases in DHA in the brain are associated with cognitive decline during aging and with onset of sporadic Alzheimer disease. DHA has a positive effect on diseases such as hypertension, arthritis, atherosclerosis,, adult-onset diabetes, mellitus, thrombosis, and some cancers.
In conclusion, if consuming DHA through your diet is impossible, you can purchase DHA as a supplement in two common forms: Fish oil capsules or DHA extracted from algae. Consuming DHA may help support body tissues in which DHA is prevalent — especially the brain, nervous system, heart, retinas, and colon. Staying healthy is important, have you had your DHA today?

Antioxidants are the body’s main defense against free radicals as they work against the substances that create oxidants and the reactive substances that result from oxidation and reduction. Antioxidants neutralize free radicals by supplying the missing electron so that the molecule may be stabilized. There are many different types of antioxidants ranging from dietary antioxidants to those that the body produces itself. The four major antioxidant nutrients are vitamin A (beta carotene), vitamin C, vitamin E, and selenium. Vitamin A, the first vitamin to ever be isolated, is essential for the proper function of the eyes and maintenance of the skin. It is found in the retina of all mammals as well as the liver. Vitamin A works to increase our resistance to infections by keeping all the linings in the body healthy. It is necessary for the health and moisture of the skin and the specialized cells lining the eyes, nose, mouth, throat, lungs, esophagus, stomach intestines, and urinary tract. When these cells don’t have sufficient vitamin A, they thicken and harden, which is extremely detrimental to health and makes us more susceptible to infection. Vitamin A also protects the body from cardiovascular disease and cancer, and is necessary for new cell growth, something that is extremely important in slowing the aging process. Beta carotene is the best known of the two carotenoids that form vitamin A, being composed of two vitamin A molecules that are split apart by liver enzymes when the body is low in vitamin A. If body levels are sufficient, the enzymes remain inactive and beta carotene does not divide, making it a safe source of vitamin A, without producing the toxic effects that come with high levels of vitamin A itself. If excess beta carotene is consumed it is stored in fat tissue or circulated in the blood. Beta carotene is one of the most powerful antioxidant nutrients as it can prevent free radical formation and inactivate existing free radicals. Once free radicals have been formed, it traps them and breaks the chain reaction that occurs. Vitamin C holds a crucial role in many body processes that are necessary for life, among these being its role in collagen formation. Collagen is important in the every structure of the body, as it works like glue to bind cells together to form tissues. The integrity of collagen depends on vitamin C. Vitamin C also functions as one of the most powerful free radicals to prevent the damage that contributes to aging and age-related diseases. It also works against pollution and toxins that damage cells and cause mutations, possibly even reducing some food carcinogens and protecting lung lining fluids against damage by air pollution. Vitamin C is important in the immune system and it also increases immunity to infectious diseases, lowers total cholesterol, enhances the effect of vitamin E, promotes wound healing, growth, tissue repair, and helps with the utilization of iron. Vitamin E prevents aging by prolonging the useful life of cells found in the body. It also works to protect vitamin C and vitamin A from free radical activity so that they may remain potent. Vitamin E has the ability to stop a free radical chain reaction as it is happening and plays an extremely important role in preventing the per-oxidation of lipids (cholesterol). It protects the cell membrane, which in turn causes it to help protect the body from disease.
Selenium, one of the ten essential trace minerals, can be found in all tissues of the body. It is best known for its antioxidant role and its function in fighting cancer. It protects the liver from damage and works to stop lipid per-oxidation. Selenium is vital in maintaining the elasticity of body tissues and preventing the oxidation of fatty tissue, in turn combating the effects of aging. Selenium causes the skin to be healthier, muscle mass and tone are more easily maintained, and the heart is strengthened. Selenium works along with vitamin E, enhancing the effects of each other. It is important to get our vitamins and minerals on a daily basis to maintain a health happier life.

Vitamin C is the most widely taken nutritional supplement on the market and is available in a variety of forms, including tablets, drink mixes, crystals in capsules or bulk powdered crystals. Vitamin C is present in mother's milk and, in lower amounts, in raw cow's milk, with pasteurized milk containing only trace amounts. This vitamin is most present in the liver and least present in the muscle but needed through out the body. Vitamin C is required for the synthesis of collagen, an important structural component of blood vessels, tendons, ligaments, skin, and bone. Vitamin C can regenerate other antioxidants such as vitamin E; in the body vitamin E can regenerate C as well. This vitamin is required for the growth and repair of tissues in all parts of your body. Relatively large doses of vitamin C may cause indigestion, particularly when taken on an empty stomach. It has been shown that smokers who have diets poor in vitamin C are at a higher risk of lung-borne diseases than those smokers who have higher concentrations of Vitamin C in the blood. Biological tissues that accumulate over 100 times the level in blood plasma of vitamin C are the adrenal glands, pituitary, thymus, corpus luteum, and retina. Studies suggest the presence of large quantities of sugar either in the intestines or in the blood can slow absorption of this vitamin. Several studies have demonstrated a blood pressure lowering effect of vitamin C supplementation. Also, when consumed in high doses it appears to interfere with the blood thinning effects of warfarin by lowering prothrombin time, as noted in case reports in the 1970s so consult your doctor if on medications.. In one Study, researchers instructed patients with documented coronary artery disease to take a single oral dose of either 2 g vitamin C or a placebo. Results, the researchers discovered that high doses of vitamin C can help prevent blood platelet sticking and fight cholesterol oxidation. Also, researchers discovered this vitamin can reduce the formation of potentially carcinogenic nitrogen-containing compounds in the stomach, offering protection from stomach cancer, researchers have reported. French and German researchers found that vitamin C appeared to keep cells in the blood vessel wall from dying. The researchers, who studied immune indicators, such as serum immunoglobulin and neutrophil phagocytosis (how well your white blood cells can engulf and digest foreign bodies), concluded that vitamin C exerts a remarkable immuno-modulating action, in other words, improved immune function in all those who consumed vitamin C on a regular basis. What are deficiency symptoms for vitamin C? Scurvy is a disease resulting from lack of vitamin C, since without this vitamin, the synthesized collagen is too unstable to perform its function. Scurvy was common among those with poor access to fresh fruit and vegetables, such as remote, isolated sailors and soldiers. The amount of vitamin C required to prevent “chronic disease” appears to be more than that required for prevention of scurvy which is 30 – 60 milligrams per day. Based on scientific research, vitamin C also appears to improve oral absorption of iron, which is good news for those that are anemic. Half of us in the United States will die from heart disease. The foundation of heart disease is atherosclerosis, the narrowing of our arteries with plaque. Treatment with vitamin C has consistently resulted in improved dilation of blood vessels in individuals with atherosclerosis as well as those with angina pectoris, congestive heart failure, high cholesterol, and high blood pressure. Researchers believe this protection from cell death could explain previous study findings which suggest that vitamin C benefits blood vessel function in people with congestive heart failure. Vitamin C supplements are also generally regarded as safe in most individuals in recommended amounts, although there are rarely reported side effects including nausea, vomiting, heartburn, abdominal cramps, and headache. In addition, this vitamin is required for the synthesis of l-Carnitine, a small amino acid that is essential for the transport of fat to cellular organelles called mitochondria, for conversion to energy. If you have chronic fatigue syndrome, vitamin C may help by boosting energy production through the mitochondria.
Therefore, as in many studies of vitamin C intake and cardiovascular disease risk, it is difficult to separate the effects of vitamin C on stroke risk from the effects of other components such as diet and the consumption of fruits and vegetables. As with all dietitians an emphasis on the benefits of a diet rich in fruits and vegetables is important to maintain a healthy cardiovascular system. If one can not consume fruits and vegetables on a daily basis then supplementation of vitamin C is need in either capsule of tablet to fight the risk of disease.

DHA is a fatty acid that is essential for many body processes and structures. Fatty acids are the building blocks that create lipids, which are important nutrients that make up 25 to 45 percent of total body energy for most of those who are living in industrialized countries. The majority of dietary fatty acids are made from dairy products, meat, margarine, and vegetable oils. Lipids are important because they store and transport energy from one part of the body to another and they also insulate and mechanically protect certain parts of the body. Any fat that is eaten is converted by the body into fatty acids, where it is then burned for energy, stored, or synthesized into other acids which are called prostaglandins. Some fatty acids are also vital structural components of cell membranes. DHA is part of a special class of highly concentrated, long-chained, polyunsaturated fatty acids called omega-3 fatty acids. Omega-3 fatty acids are looked at as one of the most fundamental molecules in the structure and activity of the membranes of all cells. They have a huge influence on the production of cellular regulatory compounds which are known as eicosanoids. They also are highly specialized in their function in neurological tissues, especially the retina of the eye. It is also very likely that omega-3s have specific and beneficial effects on the heart muscle, while they also influence the production of substances that control immune responses. Fatty acids are short-chained, medium-chained, or long chained. Short-chain fatty acids are water-soluble and absorbed directly from the intestine into the bloodstream. They are generally used for immediate energy and can be found most abundantly in dairy products. Long-chained fatty acids are more emphasized when it comes to health concerns as they are stored in cell membranes and have a huge affect on membrane protein function. Their behavior in tissue membrane is what makes them greatly influential in health. Besides the length of the chain, fatty acids are also described by their saturation. Saturation means how many hydrogen atoms the fatty acid carries. Fatty acids that carry as many hydrogen atoms as they can are called saturated fatty acids, while those that lose a pair of hydrogen atoms become unsaturated. This loss of hydrogen atoms creates a double bond between the two carbon atoms on either side of the missing hydrogen atoms. Those fatty acids that have one double bond are called monounsaturated fatty acids, while those with two or more double bonds are called polyunsaturated fatty acids. Most omega-3 fatty acids are highly unsaturated and have five or more double bonds.
EPA and alpha-linolenic acid are most commonly found in plant sources. DHA and EPA are made in phytoplankton, which is consumed by fish, mollusks, and crustaceans. The above reason is why these two essential fatty acids are found mainly in the aquatic food chain. LNA and EPA cannot substitute for DHA in all metabolic functions, even though DHA and EPA are more able to cover for each other in certain metabolic functions. It has been found that LNA is less effective than EPA which is less effective than DHA in enriching tissues, meaning that food sources such as vegetables and seed oils are not as good of sources than sea foods or other foods that are enriched with DHA and EPA. DHA in itself provides most of the health benefits displayed in research, to take essential oils that contain no DHA would limit the health benefits discussed above and from other sources.

Date:
April 12, 2008 11:06 AM
Bilberry extract is taken from the Vaccinium myrtillus, or bilberry, a small blue berry that has been used traditionally for the treatment of conditions now known to be due to inflammation and the action of free radicals on the body. Among these is atherosclerosis, or hardening of the arteries, caused by the free radical oxidation of the low density lipids that carry cholesterol around the bloodstream, and that cause deposition of fatty plaques on the arterial walls and eventually constricts them to a stage that can cause heart failure or a stroke, depending on whether the arteries are close to the heart or in the brain. However, additional to treating this condition, bilberry has also traditionally been used for the treatment of varicose veins and also for certain eye conditions. In fact it was during the Second World war that the Royal Air Force in Britain received reports from pilots that their night vision improved after eating bilberries. Not only their vision, but the restoration of night vision after exposure to glare. This was extremely important to war-time pilots who had to be able to rapidly adapt their vision to fly their plane after exposure to searchlights and explosive detonations. That is the reason for anything that appeared to promote this essential adaptation to be reported. The pharmacology of these effects have been found to be due to the anthocyanosides in which bilberries are particularly rich. Anthocyanosides consist of an anthocyanaidin backbone, to which one of either arabinose, galactose or glucose can be bound. Since bilberry contains five of these anthocyanadins, then there are fifteen different anthocyanosides in the fruit concentrate. The area of the retina that appears to control night vision, and the transition from day to night sight, is called the epithelium which is connected with purple vision. Anthocyanosides seem to have an affinity for this part of the retina, and in so doing plays an important part in this type of vision, specifically night vision although it is also beneficial in improving day vision. Although bilberry also contains vitamins A and C, hydroquinone and tannins, it is the anthocyanosides that provide it with its unique antioxidant properties, and also its effect upon collagen fibers. It can cross-link collagen fibers to help overcome weaknesses in the connective tissues such as cartilage, tendons and the walls of blood vessels. Its effect as an antioxidant is to prevent the cleavage of collagen by the cyzymes that are secreted by leukocytes generated by the immune system. By preventing histamine release, and release of prostaglandins and other proteins and cells mobilized during the immune inflammatory response to the detection of foreign invasion into human tissue, anthocyanosides can help to reduce inflammation and to protect against other extreme reactions of the immune system that can harm the organism it evolved to protect. The most powerful property of anthocyanosides are their antioxidant properties: perhaps even its only property once all of the conditions it helps to protect against are fully understood. An antioxidant combines with free radicals and destroys them. Free radicals are particularly vile chemical entities that require an electron to make them stable, and they take this electron from the nearest source. This can result in oxidation and destruction of many bodily tissues leading to premature aging, atherosclerosis, eye damage and many other problems that result from the destruction of body cells and tissue. The various constituents that make up bilberry act in concert to scavenge the free radicals and increase the supply of oxygen to the eye. The benefits of this are in helping to prevent cataracts and glaucoma, the latter due to the effect of the anthocyanoside cross-linking effect on the structure of the collagen in the eye. It can also help in cases of macular degeneration that affects the central area of the retina which might be due to the same property of there glucoside. Moving away from the eyes and back to the vascular system, the collagen cross-linking properties of the flavonoids, which is what anthocyanosides basically are, can help to repair damaged vein tissue by strengthening the vein walls themselves, and also by providing support for the cell membranes, or outer layers of the cells. This in turn builds up more strength in the vein tissue below the outside walls and contributes to an overall reduction in the weakness of the vein. This in turn enables it better to withstand the internal pressure put upon it by the failure of the valve that created the problem. In this way bilberries can be used to help repair the damage done by varicose veins and improve the function of the vein in returning blood to the heart from the extremities of the legs and also to help reduce the pain and swelling of varicose veins. In addition to these beneficial effects on the vascular system and the eyes, bilberry can also help to decrease the permeability of the blood-brain barrier to pollutants, drugs and other undesirable chemicals by improving the resistance of the capillaries in the brain to the transfer of such substances through their walls. It does so by preventing the collagen of the capillaries in the brain being degraded either by enzymes or other agents, Also, by helping to strengthen that collagen structure so that it becomes more impermeable to the larger molecules that form the pollutants. A lesser known constituent of bilberry is myrtillin, an anthocyanoside monoglucoside that is also available in all green plants, that possesses anti-glycemic properties. What this means is that it can reduce hyperglycemia and glycosurea, and so reduce blood sugar without reducing the blood sugar level to dangerously low levels. In other words it is an ideal insulin substitute. Native Americans used green plants for teas for centuries and were free from diabetes until the came into contact with Europeans and adopted their dietary habits. Although the case has to be proved, it appears highly likely that it was the myrtillin that kept them free from a condition that affects so many other races. Irrespective of that, however, it is for its powerful antioxidant effect that bilberry finds its best use, and also its effects on varicose veins. However, all of the above health benefits that bilberry provides, can likely be laid at the door of the combined antioxidant effect of its vitamin C content and the anthocyanosides – including the glucoside myrtillin.

Weakness of blood vessels is often seen during the aging process when blood vessels become fragile. Dark bilberry fruit has been shown to reduce blood vessel permeability, improve capillary resistance, and provide antioxidant properties, to scavenge free radicals. One way to fight the aging process of the body is to promote health in the vascular system by eating nourishing foods, exercising, and learning how to handle stress. Evidence shows that eating five servings or more a day of fruit and vegetables can reduce the risk of heart disease, cataracts, and some other disorders that related to blood vessel health. The dark pigment in fruits and vegetables has many health advantages. A lot of people think that the only way to improve blood vessel health is to reduce blood cholesterol, minimizing the risk of a heart attack. That is an essential goal, but blood vessels should also have strength and integrity to maintain their health in order to carry nutrients and oxygen through the body to feed the tissues. As we age, eye function begins to diminish and causes a lot of people to fear that they are losing their eyesight. The blood vessels decline in function, but there are other factors such as the reduction of arrestin and rhodopsin. Arrestin is a protein while rhodopsin is the light sensitive pigment that can be found in the retina. The dark pigment of fruits and vegetables is extremely important to blood vessels and the health of the structures and proteins of the eyes. Brilliant colored fruits and vegetables may prevent strokes, heart disease, and help long-term vision because they improve integrity of blood vessels. Bilberry fruit has been studied for over 40 years for its supportive effects on blood vessel health, blood circulation, and lymph flow. Blood vessels in the brain, heart, eyes, stomach, veins in the legs, and actually anywhere in the body have the potential to leak. In many regions bilberry extract has been used to support individuals with microcirculatory disorders including varicose veins, atherosclerosis, and degenerative retinal conditions including macular degeneration and cataracts. Diabetes, atherosclerosis, poor diet, lack of exercise, smoking, excess alcohol and an inability to handle stress can all contribute to blood vessel disorders and cause the capillary’s membrane to thicken, therefore, increasing capillary permeability causing edema and leaking of fluid. During the aging process, oxidative damage occurs by free radicals in the eyes, which then causes a loss in the transparency of the lens. Symptoms that occur because of this are blurred vision, increased sensitivity to glare, reduced visual acuity, color perception, and light sensitivity. When the eye structure begins to break down, vision impairment and cataract formation result. Bilberry extract has been shown to improve vision and twilight vision, helping the retina adapt to darkness and glare. With aging, a gradual degenerative process is experienced which is caused by free radical damage to our body’s genetic material, cell membranes, and tissues. Free radicals attack blood vessel endothelial cells, and they begin to rupture. Antioxidants help to prevent AMD and reduce the damage of the retina’s photo receptors. In summary, blood vessel health is an important part of age management. By improving diet, managing stress, exercising, and supplementing with bilberry extract, one can promote the health of blood vessels throughout the body, and therefore, support the eyes.

Date:
March 19, 2008 08:17 AM
The fact that beta carotene is stated to be a safe form of vitamin A suggests that vitamin A is in some way unsafe. In fact an overdose of vitamin A can lead to any one of a number of conditions, including nausea, jaundice, vomiting, abdominal pain and headaches. This vitamin is fat soluble, and so any excess is not easily washed out of the body but can build up in the tissues. Toxicity in the liver can occur at fairly low concentrations, and the toxicity of the vitamin is increased by excessive alcohol intake. However, toxicity only occurs with vitamin A already formed such as that obtained from liver. There are several forms of vitamin A, including the retinoid form originating from animal sources and the carotenoid forms that have a vegetable origin. Carotenoids are converted to vitamin A in the liver, but the higher the concentration of beta carotene in the body, the smaller the percentage that is converted to vitamin A, so beta carotene is a safer source of vitamin A than retinoids. It is only the finished form of vitamin A that is toxic, and beta carotene is therefore self-regulating in its production. This vitamin is stored in the body in the form of the alcohol (retinol) and of retinyl esters. Studies have indicated that as much as 95% if the stored vitamin is in the form of the ester. The liver is responsible for releasing vitamin A to the body as it is required. One of its better known effects is on vision, and the old wives tale that carrots help you to see in the dark has an element of truth in it. In order for it to aid vision, retinol is oxidized to the aldehyde, retinal, that forms a complex with a molecule of opsin, a light sensitive protein found in the retina. Rhodopsin, as the complex is called, is an essential component of the biochemical chain of events that lead to the perception of light. It is extremely sensitive, and enables you see in very low levels of light. In other words it is essential for good night vision, so carrots do help you to see in the dark! When a photon of light hits a molecule of rhodopsin, it leads eventually to an impulse being sent up the optic nerve to the brain. One of its properties is its reaction to white light. When rhodopsin is exposed to white light it loses its pigmentation, and hence its photoreceptor properties and can take 30 minutes to regenerate. That is why you lose your night sight if your retina is exposed to bright light. The more rhodopsin you can generate the quicker you develop night sight. The other biochemical processes of the vitamin include the synthesis of some glycoproteins and maintenance of normal bone density. Without vitamin A, calcium is not properly absorbed by the body and glycoproteins are involved in this process. A deficiency of vitamin A can lead to the abnormal development of bone and other health problems, so there are limits between the levels of vitamin A in the body that must be maintained: above or below these limits will lead to health problems, some of which can be extremely serious. Most of the biochemistry of vitamin A in the liver is initiated by the presence of alcohol, and otherwise it is though to passively store the vitamin until needed when it is released into the blood. There are several ways in which the presence of alcohol allows the liver to deplete its store of retinol, but generally there are a number of enzymes that, in the presence of ethanol, can render vitamin A into a water soluble form that is excreted by the urine. The benefits of vitamin A other than its effect on night sight and the healthy development of bone tissue, includes a powerful antioxidant effect that neutralizes free radicals that can destroy body cells. These free radicals are generated by the body’s metabolism in generating energy from blood glucose, and are also created through exposure to pollutants such as cigarette smoke and traffic fumes. They are electron deficient, so when they are generated they grab an electron from tissue close by which destroys the cells involved. This can lead not only to the appearance of premature aging as the skin cells are damaged but also to serious health problems such as atherosclerosis and some forms of cancer. Vitamin A helps to protect against these by destroying the free radicals before they can do damage. It also helps build up resistance against infections by supporting the immune system. Beta carotene is converted to vitamin A either by cleaving at the center of the molecule, or by breaking it down from one of the ends. This latter process is carried out in the small intestine, and the resultant vitamin stored in the liver in the ester form. Only a proportion of what you eat is converted to retinol ester in this way, and the more beta carotene you consume, the less is converted, so you can never suffer from an overdose of beta carotene-derived vitamin A. It might turn you yellow, but you won’t suffer from excess vitamin A since the excess beta carotene is stored in your body fat, including the subcutaneous fat reserves. Alpha carotene can also be used in the synthesis of vitamin A, but not as actively as beta carotene. The best natural sources are fruits and vegetables, especially the red, yellow and orange varieties such as carrots and apricots, and also the leafy green vegetables, although supplements are also a convenient way of maintaining your beta carotene uptake. It is a much safer supplement than straight vitamin A for the reasons explained earlier. The supplement is not useful just for its antioxidant effect, but also for its ability to protect you from excessive exposure to the sun. While not as effective as a good sun blocker, beta carotene does provide some protection. There is no doubt that beta carotene is a safer way to maintain an adequate vitamin A uptake due to the fact that you cannot take an overdose, since an overdose of beta carotene does not translate into the same dose of vitamin A, and the change is self-regulating. It is therefore safer to obtain your vitamin A needs from colored fruits and vegetables or beta carotene supplements than from eating liver, from which the retinol is in a form that can cause damage in the event of consuming an excess. The old adage that you should never eat polar bear livers is a true one, and certainly has a provable scientific basis, so use beta carotene as your main vitamin A source for maximum health benefits in the safest possible way.

Date:
October 23, 2007 10:00 AM
Lutein is a plant pigment, and protects protection from the sun needed to prevent damage to the skin and eyes from its strong ultra violet (UVB) radiation. Lutein is a carotenoid and strong antioxidant that is found in red, yellow, orange and dark green fruit and vegetables such as broccoli, curly and sea kale, spinach, carrots peppers and squashes. It is also available from egg yolks, corn and some fruits such as pomegranates. It is the colored pigments, especially the reds, yellows and oranges, in which lutein is most found. Lutein can also prevent cataracts and provide benefits for age related macular degeneration. However, before discussing the benefits, it is necessary to discuss exactly what these conditions are and what causes them. Let’s have a heads up on cataracts first. A cataract takes the form of a clouding of the lens of the eye that leads to blurred vision and eventual virtual blindness when the cloudiness is extreme. It is not blindness due to problems with the nerves of the eye, but due to the lens become cloudy, and scattering light entering the eye. It is not a film over the eye as many people believe, but a cloudiness of the lens, and cataracts can normally be treated by removing the whole lens and replacing it with a lens implant – or a synthetic lens. It is not fully understood how lutein can help cataracts, but studies have shown that those take a large quantity of lutein in there diet have up to 50% less chance of getting cataracts that those that do not. It has also been demonstrated that men who ate broccoli and spinach regularly had a 25% less chance of getting cataracts. The same is true of those that include a lutein supplement of around 6 mg daily, although up to 20 mg is considered an effective dose. However, it not only through its properties in protecting against cataracts that lutein can help to preserve the health of your eyes. It is also through its effect on macular degeneration. The macula is small part in the center of the retina that allows you to see central vision in high detail, especially close up when you use the center of your eye. Age-related macular degeneration, known as MD, affects your macula so that you can see fine round the edges, but your central vision is blurred. It is therefore difficult to drive, read or carry out tasks that need good central focus. You will find it next to impossible to thread a needle for example. It can come on very slowly, in fact so slowly that you never notice it because the change from day to day, or even week to week, is so small. It is not coincidence that lutein is concentrated in the macula, and that a lutein supplement can help to prevent macular degeneration. Lutein is believed to filter out some of the blue wavelengths of light, and it is the blue wavelengths that are though to cause free radical damage and oxidative stress to various organs of the body exposed to light, but specifically the eyes. That is why it is believed that lutein helps to prevent macular degeneration, and studies have indicated a good supplement to consist of up to 30 mg each day. It can also protect the skin from damage by UV radiation, and also prevents free radical damage to skin cells causing premature aging of the skin. The latter occurs through its antioxidant properties, while the former is because if its light filtering properties. It can not only filter out the blue light that can cause macular degeneration but also ultra-violet radiation that affects the skin and can cause skin cancer. There is a fine line between the blue and ultra violet wavelengths from sunlight, and both can contribute to certain medical conditions. However, the absorptive properties of lutein are such that it can absorb the more harmful of these. The antioxidant properties of lutein are important in their own right, and can help to reduce cholesterol deposition in arties and help to maintain a healthy arterial wall thickness. The same is true of any carotenoids that reduce heart problems, some cancers, especially of the cervix, stomach and lungs, and others that can be caused by free radical action and narrowed arteries such as strokes and brain hemorrhages. Although it is not one of those supplements considered essential, lutein is biologically essential in that it cannot be produced by the body. It has to be taken through the diet. There is no specific recommended daily allowance (RDA) because life can go on without it, but it does play a role in your everyday health. However, the average person has a lutein intake less than that needed to take advantage of its UV protection or antioxidant effect. As previously stated, the effective dose is considered to be 30 mg daily, and the average American intake is about 2 mg. That’s an awful lot of egg yolks or tomatoes you are going to have to eat! If you do intend to take your lutein from the natural source, then it much more easily assimilated into your body if not overcooked. Lightly steaming is the best way to prepare your vegetables for maximum nutritional effect. You can also take lutein as a supplement in the form of tablets, creams and drinks, and can also be found in other supplements that contain carotenoids such as lycopene and beta-carotene. Although not consider essential to life, do not underestimate the health benefits to be gained from a diet high in lutein, especially if you value the health of your eyes. All strong antioxidants provide you with health benefits due to their ability to destroy the free radicals that in turn destroy the DNA in your body cells, and disrupt the cells themselves. Combine that with their action as filters to the damaging rays of the sun and you have in lutein a plant product that is far reaching in the health benefits that it can provide you with. If you are looking for a lutein supplement, stop into your local or internet health food store for lutein is an over the counter supplement.

July 09, 2007 01:21 PM
A plant pigment provides sun protection from the inside out. Energy on earth begins with the sun’s rays, which spark the photosynthesis in plants that ultimately powers all life. (Petroleum is the residue of prehistoric plants crushed over eons into liquid form.) But the sun’s energy is not totally benign for us humans; excess exposure can cause skin to wrinkle and eyesight to dim. Enter lutein. This plant chemical, reddish-orange like the setting sun, has become a hot commodity over the past several years because of its ability to protect both eyes and skin against sun damage. A member of the carotenoid family of nutrients, lutein is generally paired with its partner, Zeaxanthin, in a wide variety of foods, including egg yolks, fruits, corn and leafy greens such as spinach (where its bright color is masked by the green of chlorophyll). That’s a good thing, since your body can’t make lutein and so needs to obtain it from your diet. Skin Shield The sun produces a whole spectrum of light rays, from the visible (red through violet) to the invisible or ultraviolet (UV). UV rays—both ultraviolet-A (UVA) and ultraviolet-B (UVB)—are troublemakers. They attack collagen, the protein that gives skin its shape, which leads to wrinkles and other signs of aging. What’s worse, UV is also capable of damaging skin cell DNA, a process that can promote cancer development. And UV isn’t the only culprit: The sun’s visible blue rays are believed to help create harmful molecules called free radicals within the skin. The clue to lutein’s importance in fending off skin damage lies in the fact that it is found throughout both the outer (epidermis) and inner (dermis) skin layers, where as an antioxidant it fights free radicals and as an orange pigment it soaks up blue light. In one study, using lutein both orally and topically produced improvements in skin hydration and suppleness (Skin Pharmacology and Physiology 4/19/07). Lutein has also shown an ability to counter the inflammation and immune system suppression associated with excess UV exposure (Journal of Investigative Dermatology 2/04). Lutein Gleanings What is it? A red orange carotenoid found in a number of fruits and vegetables, generally with a similar compound called Zeaxanthin. What does it do? This powerful antioxidant helps protect the eyes against both cataracts and age-related macular degeneration (AMD); it also appears to defend the skin against sun damage and has been associated with reduced arterial wall thickness, a measure of cardiovascular health. The Eyes Have It Your eyes, like your skin, are directly exposed to the sun’s UV rays. Such exposure can cloud the eye’s lens to create cataracts. It can also disrupt the retina at the back of the eye particularly the macula, the part of the retina responsible for clear central vision—which can result in age-related macular degeneration. Not surprisingly, the eye is yet another one of the body’s lutein hot spots. This pigment is especially concentrated in the macula; in fact, of the 600 or so carotenoids that exist in nature, only lutein and Zeaxanthin are found within this all important structure. So it also isn’t surprising to learn that they Eye Disease Case Control Study, one of the first large-scale investigations into carotenoids and eye health, found a link between reduced AMD risk and high levels of lutein and Zeaxanthin. Current research has focused on the use of supplemental lutein in AMD patients, with promising results. It isn’t only the outside of your body that may benefit from lutein. When oxidized by free radicals, LDL cholesterol settles into arterial walls. Lutein may help slow this process; in one study, people with the most lutein in their blood had 80% less vessel-wall thickening than those with the least (circulation 6/19/01). So enjoy some fun in the sun. But respect the power of those golden rays, and let lutein help make playtime a safe time. –Lisa James.

By now, the benefits of obtaining essential fatty acids have been well documented. Increased media coverage and vast improvements in the science used to manufacture and screen these precious oils have helped catapult the popularity of fish oil supplementation. As a result, consumers are constantly looking for safe and effective sources of fish oil, and cod liver oil is quickly becoming the product of choice for many. Derived from the livers of Norwegian cod, Cod liver oil is considered by many to be one of the richest and most effective sources of omega-3 essential fatty acids. Its high concentrations of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) offer a wide range of health benefits, including both cardiovascular and cognitive support. In addition, cod liver oil is an excellent source of the fat soluble vitamin A and vitamin D3. together, these four key nutritional constituents work within the body to help support some of the body’s most vital systems. The extensive nutritional benefits of Cod Liver Oil: EPA Eicosapentaenoic acid is a long chain polyunsaturated acid that serves as a precursor to prostaglandin-3, a lipid substance that the body relies on to support normal platelet activity. Over the years, a multitude of studies have showcased the ability of EPA to help support healthy cardiovascular function on a number of levels. Additionally, it has been presupposed that EPA may play an important role in supporting the body’s immune system response, growth and development, and weight management.* DHA Docosahexaenoic acid is one of the brain’s primary structural phospholipid components, with equally high concentrations being found in the retinal region of the eyes. Based on extensive research, we have learned the low levels of DHA can interfere with the body’s ability to produce adequate amounts of serotonin—a neurotransmitter that helps regulate mood, emotion, memory and learning capacity. It has also been shown to help regulate healthy triglyceride levels, an essential element in supporting a healthy cardiovascular system.* Vitamin A Vitamin A plays hundreds of biological roles throughout the body, ranging from healthy vision and skin, to proper cell development and supporting minor wound healing.* Vitamin D Famed for its role in the growth and maintenance of healthy bones, vitamin D has many benefits that often go overlooked. Recent research indicates that vitamin D may help support healthy cell development, cardiovascular function, skin metabolism, and nervous system function.* NOW Molecularly Distilled Lemon Flavored Cod Liver Oil is a potent fish oil supplement that contains naturally high concentrations of the essential fatty acids EPA and DHA, as well as the fat soluble vitamins A and D. The formula uses Cod from Norway, caught during the winter and early spring months – a time when their EPA and DHA levels are at their highest. The oil in this formula is molecularly distilled, cold-pressed, and manufactured in a pharmaceutical licensed facility in Norway, under the most strict quality control standards. It is tested to be free of potentially harmful levels of contaminants, such as mercury, heavy metals, PCBs, dioxins, and other contaminants.

Hyaluronic Acid has emerged as one of the most significant anti-aging supplements in the natural products industry. As a mucopolysaccharide that occurs naturally within the human body, the highest concentrations of Hyaluronic Acid are found in the skin, eyes, and articular cartilage. Hyaluronic acid works by absorbing water within the body, which in turn supports the formation of effectiveness of the gel-like matrix that protects healthy cell structures from dehydration and free radical damage. Ongoing studies continue to suggest that it may help support some of the body’s most vital functions.* Strong, Healthy Joints At birth and well into our youth, the human body produces ample amounts of Hyaluronic acid. These levels decline, however, based on our physical activity levels, dietary habits, and other hereditary and environmental factors. Hyaluronic acid is a key component of synovial fluid and cartilage, and serves as one of the body’s most vital natural lubricants. Joint structures lack blood vessels, and there for relay on Hyaluronic acid to transport fluids and nutrients. Many structural and articular challenges have been traced back to insufficient Hyaluronic levels. Wrinkles and Fine Lines Healthy, wrinkle-free skin requires a constant supply of water. Without enough, dermal cells located deep below the skin’s surface can becomes deprived of the compounds they need, thus leaving the skin dry and dehydrated. Hyaluronic acid attracts and binds large amounts of water at the cellular level to ensure that the skin has everything it needs to remain smooth, elastic, and youthful-looking. Some published reports suggest that a child’s ability to produce abundant amounts of Hyaluronic acid may explain why they heal so quickly, often without permanent scarring. Because of the many roles it plays within the body’s connective and epidermal tissues, Hyaluronic acid is becoming more and more accepted as a way to help encourage the body’s natural wound-healing processes. Vision and Eye Health In addition to cartilage and synovial fluid, the eyes contain some of the body’s highest concentrations of Hyaluronic acid. In fact, the vitreous humor (the Eye’s Core) is made up almost entirely of Hyaluronic acid. This gel-like structure absorbs shock, supports vision, and protects the retina from being damaged. It is believed that many common vision and ocular problems may be a result of poor Hyaluronic acid production during adulthood.* Each Vcap contains 100mg of Hyaluronic acid, along with Alpha Lipoic Acid, standardized Grape Seed Extract, and pharmaceutical grade L-Proline for support. Compare Now’s 100mg formula to some 50mg formulas that do not include supporting antioxidants for the same price, and the choice is clear!

Enjoy the Rainbow – the Color Wheel of Fruits and Vegetables
We’ve all heard the statistics, and have probably seen the signs in the produce section of our favorite grocery store: eating 5 servings of fruits and veggies a day is important,
Chances are also pretty good that we’ve also seen the newest food pyramid, encouraging Americans to “eat a rainbow of frits and vegetables.” That is, choose from the rich variety of colors for the best all-around health benefits.
In this Ask the Doctor, we’re going to look at the unique health components of different colored fruits and vegetables, and why they’re so important. Plus, we’ll learn about supplemental options, like fruit and vegetable drink mixes, for those days when our diets just aren’t that great.
Q. What’s the big deal about fruits and vegetables?
A. Well, for the main reason that they are whole foods – created by nature (or at least generations of farming) and are rich in a variety of nutrients. Processed foods can’t match the health benefits of strawberries or broccoli – items that have fiber, vitamins, and enzymes built right in.
Q. What does “eating a rainbow” of fruits and vegetables really mean?
A. This is simply an easy way of remembering to get as much color variety in your diet as possible to maximize your intake of a broad range of nutrients. The colors of fruits and vegetables are often a tangible clue to the unique vitamins and other healthy substances they contain. Getting a variety of colors, therefore, means getting a variety of the essential nutrients your body needs to stay healthy and strong.
Enjoying the Rainbow: Fruit and Vegetable Benefits:
Q. Can you tell me a little more about the healthy components of fruits and vegetables?
Let’s take a look at some of the most well-studied and important nutrients:
Quercetin is found in apples, onions and citrus fruits (also is hawthorn and other berries and apple-related fruits usually used in traditional herbal remedies and modern supplements). It prevents LSL cholesterol oxidation and helps the body cope with allergens and other lung and breathing problems.
Clinical studies show that quercetin’s main points of absorption in the body appear to be in the small intestine – about 50%. The rest – at least 47% is metabolized by the colonic micro flora – the beneficial bacteria such as Lactobacillus acidophilus and Bifidobacterium longum. You may consider adding these beneficial bacteria (found in yogurt) either through the diet or a supplemental form.
Ellagic Acid is a component of ellagitannins – dietary polyphenols with antioxidant (and possibly anticancer) properties. Polyphenols are the basic building blocks of many plant-based antioxidants. More complex phenolic compounds, such as flavonoids are created from these molecules.
Ellagic acid is found in many fruits and foods, namely raspberries, strawberries, pomegranates, and walnuts. Clinical studies suggest that ellagitannins and ellagic acid act as antioxidants and anticarcinogens in the gastrointestinal tract.
Ellagitannins are durable antioxidants, and happily, they do not appear to be diminished by processing, like freezing. This means the benefits are still strong, even in frozen packs of raspberries or strawberries, or some of the better multi-ingredient supplement drink mixes.
In scientific studies, ellagic acid also showed an anti-proliferative effect on cancer cells, decreasing their ATP (adenosine triphosphate) production. ATP is the molecule that provides the primary energy source for the cells in our bodies. In a sense, ellagic acid seems to deprive cancer cells of their fuel.
Beta-Carotene: Probably the best-known of the carotenoids, beta-carotene is converted by the body into vitamin A. Many vegetables, especially orange and yellow varieties, are rich in this nutrient. Think summer squash, yams and of course, carrots.
Beta-carotene has long been associated with better eyesight, but it has other benefits, too. In a scientific study, beta-carotene decreased cholesterol levels in the liver by 44% and reduces liver triglycerides by 40%.
Lycopene is a carotenoid mostly found in tomatoes, but also in smaller amounts in watermelon and other fruits. Clinical studies have shown that lycopene consumption may decrease the risk of prostate cancer. In fact, high intakes of lycopene are associated with a 30% to 40% reduced risk. And, as good as beta-carotene is, its cousin, lycopene, seems to be an even stronger nutrient, protecting not just against prostate cancer, but heart disease as well.
Lutein is found in many fruits and vegetables, including blueberries and members of the squash family. Lutein is important for healthy eyes, and in fact it is found in high concentrations naturally in the macular region of the retina – where we see fine detail. It is one of the only carotenoids, along with its close sibling zeaxanthin, that is found in the macula and lens of the eye.
Lutein also supports your heart, too. In a scientific study, lutein reduced atherosclerotic lesion size by 43%. In other words, high intakes of lutein may actually help prevent coronary artery disease!
Interestingly, as is the case with lycopene, cooking or processing foods with lutein may actually make it more easily absorbed.
In clinical studies, men with high intakes of lutein (and its close cousin, zeaxanthin, found in broccoli and spinach) had a 19% lower risk of cataract, and women had a 22% decreased risk, compared to those whose lutein intakes were much lower.
Vitamin C: One of the best-known nutrients out there, vitamin C keeps our immune system strong; speeds wound healing, and promote strong muscles and joints. A free-radical fighter, vitamin C prevents oxidative damage to tissues, builds strength in collagen and connective tissue, and even reduces joint pain.
Sources of vitamin C are scattered throughout the spectrum of fruits and vegetables.
Potassium: Most Americans are deficient in potassium. For the most part, it’s hard to get too much of this valuable mineral. Potassium does great things for our hearts. Higher intakes of dietary potassium from fruits and vegetables have been found in clinical research to lower blood pressure in only 4 weeks.
Many researchers believe that the typical American diet has led to a state of chronic, low-grade acidosis – too much acid in the body. Potassium helps change pH balance to a more alkaline environment in the body and increases bone density.
This was proven in the long-running Framingham Heart Study which showed that dietary potassium, (along with magnesium and fruit and vegetable intake) provided greater bone density in older individuals.
Fiber is another food component many just don’t get enough of – especially if they’re eating a “typical American diet.” Fruits, vegetables and whole grains are excellent sources of fiber. However, fiber from a good fruits and vegetable drink mix should be derived from inulin and chicory root. This soluble fiber source not only adds to the overall amount of fiber you need (25 to 38 grams a day), but also provides a nice “nesting ground” for the beneficial bacteria that populate the intestines. And, even though some fiber has a bad rap for inhibiting mineral absorption, inulin and chicory root are “bone building” fibers – they actually help the body absorb calcium.
Flavonoids are an overarching term that encompasses flavonols, anthocyanidins, and flavones, isoflavones, proanthocyanidins, Quercetin and more. They are almost everywhere: in fruits, vegetables, grains, herbs, nuts and seeds – even in the coffee, wine and tea we drink. Flavonoids are responsible for the colors in the skins of fruits and the leaves of trees and other plants.
Flavonoids have many health benefits. They can help stop the growth of tumor cells and are potent antioxidants. Additionally, flavonoids have also been studied for their ability to reduce inflammation.
Anthocyanins: High on the list of important “visible” nutrients are anthocyanins. They color fruits and vegetables blue and red.
Anthocyanins are members of this extended family of nutmeats, the flavonoids. Typically found in high amounts in berries, anthocyanins are readily absorbed in the stomach and small intestine.
As antioxidants, anthocyanins dive deep into cell membranes, protecting them from damage. IT may be one reason why the anthocyanins from blueberries are considered such an important component in battling neuronal decline, like Alzheimer’s. Blackberries, raspberries, and strawberries are also excellent sources of this flavonoids group.
SDG lignans, (short for secoisolariciresinol diglucoside) are polyphenolic components of flaxseed, pumpkin and other herbal sources. Much of the recent research surrounding lignans has focused on flaxseed. In scientific and clinical studies, lignans from flaxseed support hormonal balance and may have cancer-preventing abilities. In fact, in one study, flaxseed lignans reduced metastatic lung tumor by 82% compared to controls.
The lignans in pumpkin seed, also considered a major source, target 5-alpha reductase activity.
This enzyme catalyzes the conversion of testosterone into the more potent dihydrotestosterone (DHT). DHT, like testosterone, is a steroid hormone or androgen. Androgens are responsible for the development and maintenance of masculine sex characteristics in both men and women. Excess levels of DHT can cause serious problems with prostate or bladder health. That’s why modulation of the 5-alpha reductase enzyme is so important – it helps maintain healthy testosterone and DHT levels. By balancing the levels of these key hormones, pumpkin seed lignans provide protection for prostate and bladder cells.
In addition, pumpkin seed has been shown to modulate the enzyme aromatase. Aromatase is present in the estrogen-producing cells of the adrenal glands, ovaries, testicles, adipose tissue, and brain. Aromatase converts testosterone, an androgen, into estradiol, and estrogen.
Inhibition of the aromatase conversion can help maintain a balance of healthy testosterone levels in women, which has been shown to strengthen pelvic muscles and reduce incidence of incontinence.
In fact, a clinical study, involving a pumpkin extract in conjunction with soy, resulted in significant support for bladder health. After two weeks of supplementation, 23 of the 39 postmenopausal women enrolled in the study showed great improvement in urinary frequency and sleep. By the end of the six week study, 74.4 percent of participants found pumpkin extract safely and significantly improved “nocturnia,” that is, the need to urinate frequently at night. For individuals with 2 to 4 episodes of nocturnia prior to the stud, and 81.8% improvement was seen – also showing great improvement in sleep quality. After all, if you don’t have to wake up every couple of hours to go to the bathroom you’re bound to get better sleep.
Beta glucan: Mushrooms are intense immune-boosting powerhouses due to their beta-glucan content. Three well-studied power-house mushrooms that contribute beta glucan to the diet include maitake, reishi and shiitake.
The most significant constituents of mushrooms are long chain polysaccharides (molecules formed from many sugar units) known as beta-glucan. These huge molecules act as immunoregualtors in the human body, helping to stabilize and balance the immune system.
This includes specific support of white blood cells, or lymphocytes, the primary cells of the immune system. Lymphocytes fall broadly into three categories: T cells, B cells, and natural killer (NK) cells.
In one clinical study, 165 patients with various types of advanced cancer were given maitake mushroom compounds alone or with chemotherapy. Cancer regression or significant symptom improvement was observed in 58% of liver cancer patients, and 62% of lung cancer patients. Plus, when maitake was taken in addition to chemotherapy, the immune cell activities were enhanced 1.2 to 1.4 times, compared with chemotherapy alone.
In another clinical study, researchers determined that Reishi increased the number of cancer killing white blood cells and made them more deadly to cancer cells.
And, in a scientific study of human breast cancer and myeloma cancer and myeloma cancer cell lines, shiitake compounds provided a 51% antiproliferative effect on the cells – inducing “apoptosis’ – the programmed cell death that should occur naturally.
While beta-glucan are distributed throughout the mushroom body, the beta-glucan concentrations are significantly higher in the mycelium – the interwoven fibers or filaments that make up the “feeding structure” of the mushroom.
Bioflavonoids are commonly found in bright yellow citrus fruits, including lemons, limes and oranges. They are responsible for the bright pigment found in the skin of the fruit, and are considered a “companion” to vitamin C, seeming to extend the value of the nutrient within the body.
Hesperidin is just one of the valuable bioflavonoids found in citrus. Hesperidin appears to lower cholesterol levels, as well as support joint collagen in examples of rheumatoid arthritis.
Epigallocatechin gallate (EGCG):
Polyphenols, most notably EGCG, or epigallocatechin gallate, are well-studied and powerful components of tea. EGCG has been shown to reduce colon and breast cancer risk. Green tea also boosts the immune system and encourages T-cell formation – part of the front-line defense of our bodies against sickness and disease.
Q. I’ve been seeing articles about fruits, vegetables and supplements touting “high ORAC value.” What does this mean?
ORAC is an acronym for Oxygen Radical Absorption Capacity, and is simply a measurement of antioxidant activity of nutrients. Oxygen radicals, or free radicals, are unstable molecules. They grab electrons from other cells to use for themselves, and in the process can damage them. It is believed that free radical activity plays a role in the development of many diseases such as heart disease and cancer, and also plays a role in aging.
Antioxidants help prevent this damage by “loaning out” extra electrons to stabilize free radicals/ Consider any fruit or vegetable with a high ORAC rating as having a lot of “antioxidant power.”
I know I should eat more fruits and vegetables, but it just seems so hard to get five servings a day.
The number one excuse I hear for not buying frits and veggies is that “fruits and vegetables are too expensive.” But are they really? Certainly, fresh foods that aren’t in season and have to be shipped a distance can be a bit pricey. If anyone added up how much spend on fast food, or prepackaged or processed snacks, it would probably be shocking.
Luckily, there are many ways to get your “Daily 5”. For instance, frozen fruits and veggies retain much of their nutrient profile. They can be an excellent alternative when certain foods are out of season. So too, are fruit and vegetable drink mixes – excellent supplemental sources of some of the nutrients our bodies need most.
More recently, the American
Of course, for people not accustomed to the fiber in fruits and veggies, there is some reason to think it’ll increase gas. When cell walls break down, and fiber passes through the system, it can create flatulence. Folks who eat fruits and vegetables every day generally don’t have this problem. Their systems are already accustomed to it.
For those just starting out on a better diet, however, start slowly – it helps your body adapt. Cooking vegetables can help, too, because it begins breaking down the cell walls early on.
One thing is certain, however. The “Typical American Diet” and good health are mutually exclusive. The increase in type 2 diabetes, heart disease, high cholesterol, and hypertension all point to the abuse our bodies suffer by eating diets high in fatty meats, processed sugars, and refined grains.
Q. Can I just drink fruit and vegetables drinks in place of 5 servings of fruits and vegetables?
Green drinks and fruit and vegetable drink mixes aren’t meant to replace whole foods, but they can be an excellent substitute when you’re rushed or traveling or just trying to fill everyday nutritional gaps. Their whole food ingredients absorb very easily and gently in the gut, and many of these drink mixes contain healthy doses of fiber, too.
Green drink mixes and food-based drink mixes combine many colorful fruits and vegetables and sometimes grasses in a healthy, mixable supplement assortment. While there have been many advancements in the field of green drinks, there are only a few that take the primary reason we eat into consideration: taste!
Happily, there are some companies out there with great-tasting drink mixes that also formulate based on the color concept, ensuring you get the broadest assortment of nutrients from a full range of fruit and vegetable colors to promote optimal health.
High-quality fruit and vegetable drink mixes offer the best from nature’s color wheel in a convenient and great-tasting supplement. So, the next tie you feel like taking a coffee break – try a fruit and veggie break instead. Your body and spirit will thank you.

Controlling Diabetes with Nutritional Supplements Perhaps no other disease is as closely linked to nutrition as diabetes. Not only doe nutrition play a role in its development, nutrition is also one of the disease’s most powerful treatments. Because of this strong and critical connection to nutrition, researchers have carefully studied the use of nutritional supplements in the treatment of the disease. They found that many vitamins, such as vitamin C and the B vitamins, minerals such as chromium, as well as herbs like Gymnema sylvestre, can safely, effectively, and naturally lower blood sugars and help prevent diabetic complications. What is even more important, however, is that these vitamins, minerals, and herbs can be combined together in a scientifically validated diabetic formula to work synergistically. That means their combined effectiveness is even more powerful. Like a group of good friends, these vitamins, minerals, and herbs do their best work when they are all together. In this issue of Ask the Doctor, we will talk about powerful vitamins, minerals, and herbs combined in a scientifically validated formula that people with diabetes can use every day. But before we get into the specific formula, we need to first talk about diabetes. Q. What exactly is diabetes? A. When we eat, the process of digestion breaks down our food into nutrients. Most of the food we eat is broken down into sugar (also called glucose). The sugar enters the bloodstream for delivery throughout the body and is then called blood sugar. Insulin, a hormone that helps metabolize blood sugar, is made in the pancreas-a long, skinny gland located behind the stomach. Insulin takes blood sugar from the bloodstream and delivers it into the cells that make up the various organs in our body, such as our heart, lungs, and kidneys. The sugar provides energy to the cells to keep our hearts beating, our lungs breathing, and our kidneys excreting. Type 1 diabetes, sometimes called insulin-dependent or juvenile diabetes, most often starts in childhood. In this type of diabetes, the pancreas no longer makes insulin. The sugar stays in the blood instead of going into the cells where it is needed. Because of this, all people with Type 1 diabetes have to take at least one shot of insulin every day just to stay alive. Type 2 diabetes most often starts in adults and is also the most common kind. About 90 to 95 percent of all people with diabetes have Type 2. In Type 2 diabetes, the pancreas is usually producing enough insulin. However, the body does not use it effectively. The condition known as “insulin resistance” occurs when the cells do not respond to (resist) insulin’s attempt to enter with glucose. The pancreas responds by producing more and more insulin. When the cells do not respond, high levels of glucose build up in the blood, leading to Type 2 diabetes. Almost everyone with Type 2 diabetes also is insulin resistant. Because the insulin is left unused, the pancreas thinks it isn’t needed and may eventually stop making it. People with Type 2 diabetes often need to take prescription drugs to lower blood sugar levels if dietary and lifestyle changes are not enough to control the problem. In both types of diabetes, the sugar stays in the bloodstream instead of going into the cells where it is needed and belongs. When blood sugar builds up in the blood, it causes two problems. First, the cells become starved for energy. And, over a period of time, high blood sugar levels can damage the blood vessels, nerves, eyes, and kidneys. Q. What causes diabetes? A. While scientists aren’t exactly sure why Type 1 diabetes happens, they do know the immune system is involved. A healthy immune system protects us from diseases caused by infections, such as colds or the flu, as well as diseases that start in our own cells, such as cancer. For some reasons, in certain people, the immune system becomes confused and begins attacking and destroying the cells in the pancreas that makes insulin. Scientists aren’t exactly sure why Type 2 diabetes happens either; however, they have identified that it occurs most often in certain individuals. About 80 percent of people with type 2 diabetes are overweight, have high blood pressure, and have high cholesterol levels in their blood. Q. What are the symptoms of diabetes? A. Type 1 diabetes develops very quickly. The classic signs of diabetes include: -Frequent urination, because the body is trying to get rid of the excess sugar in the blood -Intense thirst, because the body needs to replace the fluid lost through the urine -Increased hunger, because the cells need nutrients -Weight loss, because without insulin, the body begins to starve The onset of Type 2 diabetes is often very gradual and may develop without any symptoms at all. Sadly, the diagnosis most often is made only after a complication of the disease happens. Q. What are the complications of diabetes? A. The complications of diabetes happen in both types of the disease. All diabetic complications are caused by chronically high blood sugars. The longer your blood sugar levels are elevated, the greater your chances are of having complications. Circulation problems High blood sugar damages blood vessels. When high levels of sugar are continuously in the blood, the blood vessels become thicker and less flexible, causing poor circulation. Poor circulation can impair healing, especially on the feet and lower legs. High blood sugar also causes higher levels of fat in the bloodstream. The fat clogs and narrows the blood vessels. Partial blockages deprive the heart of some necessary nutrients. A complete blockage can result in a heart attack, heart pain (called angina), or stroke. Nerve damage Nerve damage makes it hard for your nerves to send messages to the brain and other parts of the body. It may cause you to lose feeling in parts of your body or have a painful pins-and-needles-like feeling. While nerve damage most often affects the feet and legs, it can also affect other parts of the body. Eye problems Diabetes can damage and weaken the small blood vessels in the retina, the part of the eye that is sensitive to light and helps you see. When the blood vessels are weak, they can leak fluid, which causes swelling in the eye. The swelling blurs your vision. If the eye damage gets worse, your eye attempts to fix this damage by making new blood vessels over the retina. But because these blood vessels are fragile, they can break open easily and bleed into the eye. Scar tissue can then form. This may cause the retina to break away from the back of the eye, which can lead to visual impairment-even blindness. Kidney damage Diabetes can also damage the blood vessels in the kidney so it can’t filter out the body’s waste. High blood pressure is also associated with kidney damage. If you have diabetes and high blood pressure, it is important to keep them both under control as much as possible. The longer blood sugar levels are left uncontrolled, the greater the amount of kidney damage that can occur. If the kidney damage isn’t stopped, some individuals may progress to needing kidney transplants or dialysis machines. All of these complications, however, can almost always be prevented. Q. How can the complications of diabetes be prevented? A. Vitamins, minerals, and herbal supplements can provide powerful tools for preventing serious complications and keeping people with diabetes healthy. The best nutritional supplement contains powerful vitamins, minerals, and herbs in a synergistic formula that can effectively lower blood sugars and provide the specialized nutrients people with diabetes need. Q. Which vitamins, minerals, and herbs should be included in a nutritional supplement for people with diabetes? A. The vitamins, minerals, and herbs in a diabetic formula should work synergistically and be clinically demonstrated to help prevent the known complications of diabetes. To get the best results, it is very important that the right ingredients are in the diabetic formula you buy. Q. How often should I take a diabetic formula supplement? A. Read the label of the diabetic formula you are considering buying. Most quality products need to be taken twice a day. Keep in mind that you will still need to take a high quality multivitamin in addition to the diabetic formula supplement. A diabetic formula is complementary. That means that it is designed to be and addition to your multivitamin routine, not a replacement. Q. Could the diabetic formula lower my blood sugar level too much? A. In general, too low blood sugar levels should not be a problem. A high quality diabetic formula containing synergistic vitamins, minerals and herbs, most often lowers blood sugars to normal levels. However, these vitamins, minerals, and herbs will not excessively lower blood sugar levels that are already normal. Q. Do I need to continue monitoring my blood sugar when taking a diabetic formula supplement? A. Diabetes is a disease that requires active participation from you. You need to be aware of your problem and be in control of it as much as possible. If you use a home glucose monitor to check your blood sugars, you may feel more comfortable by checking your levels more frequently when you first take a diabetic formula supplement. You should always follow the recommendation of your doctor or a licensed health care practitioner regarding how often you should check your blood sugar levels. According to the American Diabetes Association (ADA) and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) (as well as most licensed health care practitioners), a good blood sugar range for most people with diabetes (before a meal) is from about 70 to 150. An ideal range is 70-120. Taking a nutritional supplement formulated especially for diabetics that contain vitamins, minerals, and herbs that work synergistically in a scientifically valid formula will help you keep your blood sugars right where the Q. Can’t I just take the diabetic formula supplement and not worry about my diet? A. Unfortunately, you cannot. Successful diabetes management means doing lost of positive things. First, you need to see your licensed health care practitioner often. You need to choose foods wisely and stay active to have a positive influence on your blood sugar levels and your health. And, taking a diabetic formula supplement every day can really help. However, the diabetic formula supplement is meant to be an addition to your healthy diet, not a substitute. Conclusion Having diabetes might make you feel overwhelmed. Restrictions on what you may and may not eat might make you feel deprived and unfairly burdened. The possibility of disease complications may make you feel anxious and scared-even angry. It is only natural to ask “Why me?” Taking control of your diabetes, instead of letting it control you, can help with these feelings. Eating wisely and exercising every day are two important ways to improve your health. And, taking a nutritional supplement formulated specifically for people with diabetes every day can give you the critical control you need to direct your health for years to come. Many healthy years to come.

Date:
November 03, 2006 12:16 PM
Pycnogenol (pronounced pic-nojen-all) is a natural plant extract originating from the bark of the maritime pine that grows along the coast of southwest France. Pycnogenol® consists of particularly bioactive flavonoid species and its purity is in strict accordance with the United States Pharmacopoeia. Pycnogenol® was initially developed 35 years ago in Europe. During the past years it evolved as one of the most thoroughly researched nutritional supplements, with over 200 studies published in peer-reviewed journals. Seventy of these studies were clinical with in total more than 4,000 patients. Pycnogenol® taken in dosages from 25mg to 300mg is well tolerated and Pycnogenol® was attributed “generally recognized as safe” (GRAS) by the FDA. Pycnogenol® supports healthy capillaries The “Career” of Pycnogenol® began in Europe, where it was first used to maintain vein and capillary health. Pycnogenol® has been shown to strengthen blood vessel walls, with 15 clinical trials showing fast relief from ankle and foot discomfort. A recent study with 200 passengers on long-haul flights showed that Pycnogenol® taken before departure and again during the flight supports foot comfort and healthy circulation. Travelers typically comment that with Pycnogenol® it is much easier to put shoes on again upon arrival. Clinicians in Germany discovered that Pycnogenol® also supports healthy capillaries in the eyes. Retinal capillaries may be affected by imbalanced blood sugar levels. In a multi-center field study with 1169 subjects Pycnogenol® supported healthy capillaries in the retina and improved visual acuity to some extent. Pycnogenol® benefits the cardiovascular system More detailed investigation of the interaction of Pycnogenol® with blood vessel walls at the University of Florida, Tampa led to an amazing discovery. Pycnogenol® stimulates an enzyme in blood vessel walls that is responsible for generating the most important vascular mediator, known as “nitric oxide” (NO). NO triggers relaxation of the arteries and supports clear blood flow. Hence, NO is the body’s mediator for maintaining healthy blood pressure levels and circulation. NO plays such an important function for cardiovascular health that Dr. Louis Ignarro (UCLA) and his co-workers received the Nobel Prize for this discovery in 1987. A number of factors, including aging, can interfere with the body’s efficient production of NO. Supplementation with Pycnogenol® for four weeks was shown to restore NO production and improve blood supply to the fingertips of elderly people in a Japanese study. Microscopic evaluation of blood vessel diameter at the root of fingernails showed an increased diameter of capillaries allowing better blood perfusion. Specific sensors applied to the legs showed increased oxygen and decreased carbon dioxide presence. Better blood, nutrient and oxygen supply with Pycnogenol® benefits everybody. Italian researchers were able to show that regular intake of Pycnogenol® helps defy muscle cramps and minor pain in athletes. The relaxation of arteries has a favorable effect on blood pressure. In two clinical studies Pycnogenol® taken for at least eight weeks was found to significantly support normal blood pressure. Pycnogenol® stimulated NO generation directly translates into clear blood flow. This was first demonstrated at the University of Arizona, Tucson in smokers. Pycnogenol® dose-dependently, starting at a single dose of 25mg, countered the typical effects of cigarette smoking on the blood. Also, Italian vascular specialists found that Pycnogenol® supported the circulation of individuals on flights between New York and London. Pycnogenol® supports healthy blood sugar levels Pycnogenol® can support normal glucose levels when taken as part of a healthy diet and lifestyle plan. A clinical investigation has confirmed the significant glucose-lowering effect of Pycnogenol®. It was noted that Pycnogenol® did not affect insulin levels. Pycnogenol® appears to facilitate previously insulin-resistant cells to uptake sugar from the blood stream by yet unknown mechanisms. Pycnogenol® limits cellular irritation Two clinical studies carried out in Germany this year with student volunteers demonstrated that Pycnogenol® has a potent effect in preventing cellular irritation. Pycnogenol® inhibits a molecular “main-switch” in immune cells that triggers the onset of cellular irritation in any part of the body. Moreover, Pycnogenol® was found to inhibit so-called COX enzymes, which are involved with minor pain-sensation related to cellular irritation. Pycnogenol® sooths menstrual pain Japanese gynecologists discovered in 1999 that regular supplementation with Pycnogenol® soothes the normal discomfort of menstrual pain, particularly during cramping. Another clinical investigation of 47 women in year 2004 confirmed the effect of Pycnogenol® in addressing menstrual pain. This year a double-blind, placebo-controlled, multi-center field study with 116 women again confirmed these results. Pycnogenol® is not suitable for on-demand relief during menstruation. The studies show that Pycnogenol® reached highest efficacy when taken regularly for months. Pycnogenol® helps to support respiratory health Challenges to normal respiratory function may result from incidents the immune system perceives as harmful. Pycnogenol® offers valuable help in supporting respiration due to its immune-modulating effect and its ability to limit cellular irritation. A study at the University of Arizona found that Pycnogenol® supports clear breathing and lowers mediators of cellular irritation in the blood stream. More recently, a placebo-controlled clinical study at the University of California, Loma Linda described how Pycnogenol® supported healthy respiration in 60 children aged 6-18 years. Pycnogenol® needs to be taken continuously for prolonged periods of time for maximum benefit to the respiratory system. Pycnogenol® is investigated in clinical trials all over the world. New findings are posted on the website www.pycnogenol.com. Frank Schonlau Ph.D. is a biochemist who has spent nine years in medical research at the University Clinic of Munster Germany. His area of expertise covers vascular disorders, inflammation and dermatology. He has published more than 20 studies and review articles in the medical literature. Since entering the dietary field in 1999 he was involved in numerous studies on Pycnogenol® and communication of new health discoveries.

Date:
August 11, 2006 01:50 PM
A recent study supported by Kemin Food Asia and conducted at the College of Medicine, Catholic University of Korea suggested that lutein protects the retina from cellular damage caused by eye conditions, including diabetic retinopathy and age-related macular degeneration. The researchers injected rats with lutein prior to retinal ischemia, or reduced blood flow to the retina caused by obstruction of the blood vessels. Results showed the lutein inhibited retinal degeneration, which is marked by reduced expression levels of neuronal nitric oxide synthase and Cyclo-oxygenase-2, or COX-2. In addition, the reduction of these proteins appeared to be dose-dependent, which would imply benefit from increased exposure to this carotenoid. According to the lead author of the study, “These results suggest that a lutein supplement may protect against ischemia mediated cell death in the retina."

INTRODUCTION:
Cholesterol, the soft, waxy substance present among the lipids (fats) in the bloodstream and in all cells, is important for wide variety of physiological functions. It is essential for the formation of cellular membranes, necessary for the production of bile salts, and also plays a role in the synthesis of certain hormones.3-5
Cholesterol is both produced by the body and obtained from food. Endogenous cholesterol is formed by human cells, particularly liver cells, whereas exogenous cholesterol is absorbed through the gastrointestinal tract from food.3,4
Because cholesterol can not be metabolized for energy, it must be removed from the body once it has served its function. The major route of removal is through the liver, where it is processed and subsequently excreted from the body.3,4
Types of Cholesterol
Cholesterol is lipophilic (“fat loving” or water insoluble) by nature. It can not be dissolved in the blood, and must, therefore, be transported by carriers known as lipoproteins. These carriers are classified by density, with LDL (low density lipoproteins) and HDL (high density lipoproteins) being the most common.4,5
LDL is often referred to as “bad” cholesterol. LDLs carry cholesterol throughout the body. Conversely, HDL, or “good” cholesterol, is responsible for carrying cholesterol away from the arteries to the liver where it is eventually processed and eliminated from the body.3,4,6
Scientific studies have shown that both types of cholesterol are important indicators of cardiovascular health. But recent research, focusing on the beneficial subtypes of HDL, has found that certain fractions of HDL may be more supportive of cardiovascular health than others. The two most notably supportive HDL fractions are HDL-2 and HDL-3.7
The smaller HDL-3 is synthesized by the liver and intestines. This form, which is known as “free cholesterol-rich” HDL, scavenges or “scoops up” free cholesterol. The cholesterol is then chemically altered by the addition of an ester group. When sufficient cholesterol is esterified, HDL-3 becomes HDL-2, which is therefore referred to as “cholesterol ester-rich” HDL. HDL-2 is larger in size and has been shown to be more cardiosupportive than HDL-3.*7
HOW IT WORKS:
HDL is known to possess antioxidant activity and to help balance the body’s natural anti-inflammatory response, both of which are important for cardiovascular health, but its most important function is the role it plays in cholesterol transport.6,8 High levels of HDL cholesterol are also associated with reduced platelet activity, another key indicator of arterial and venous health.9
Both HDL and LDL levels are important indicators of healthy cardiovascular function.* Therefore, supplements that increase the level of good cholesterol can profoundly impact heart health.* In 2002, an open label pilot study was conducted at

Date:
February 27, 2006 05:53 PM
Lutein: The Antiordinary Antioxidant Lutein belongs to a class of compounds known as carotenoids. Carotenoids in general are yellow, orange, or red pigments responsible for many of the colors of the foods we consume each day. To date, over 600 carotenoids have been identified in nature, but are only produced by plants, algae and bacteria leaving humans and animals to consume carotenoids in the diet. Forty to fifty carotenoids are consumed in the typical US diet, but only 14 have been detected in the blood, indicating a selective use of specific carotenoids by the body. Lutein is one of these carotenoids found in the blood and has been increasingly associated with eye health over the last decade. Lutein’s role in eye health In the human eye, lutein is concentrated in the center of the retina in an area known as the macula. Lutein is deposited in the macula through the lutein we consume in out diet or through supplements. This area is responsible for human central vision and is colored intensely yellow due to high concentrations of lutein. Lutein is thought to be beneficial for eye health by reducing damage in the eye in two ways: 1) by absorbing blue light (blue light is thought to increase free radical formation in the eye) and 2) by acting as an antioxidant, reducing damage in the eye caused by free radicals. Leading carotenoid researchers believe these functions may lead to a reduced risk of age-related macular degeneration (AMD) and cataracts. Age-related macular degeneration Macular degeneration is the leading cause of blindness in the USA in those over 65. twenty-five and thirty million people are afflicted worldwide and currently there are no effective treatments for the disease. The disease has two forms known as dry and wet AMD. Ninety percent of AMD cases diagnosed are the dry form. In dry AMD, also referred to as early AMD, debris deposits under the center of the retina (known as the macula) interfering with its normal function. Parts of the macula atrophy, causing the central vision to slowly become dimmer or more blurry. Wet age-related macular degeneration, also known as late AMD, often develops in areas where dry AMD exists. Abnormal blood vessels grow and leak blood and fluid under the macula, causing scarring, which leads to rapid loss of central vision. Dr. Joanna Seddon published one of the first studies demonstrating a link between lutein intake and AMD risk in 1994 (1). This epidemiological study compared the risk of developing AMD to nutrient intake and showed a significant reduction in risk for developing AMD as lutein intake reached 6mg per day (57% reduction in risk). Since the Seddon study, researchers have shown that increasing dietary lutein intake raises blood levels of lutein as well as levels of lutein in the eye (2). Bone et al. demonstrated that eyes with higher levels of lutein were less likely to be afflicted with AMD (3). The latest clinical trial that investigated lutein’s role in AMD is known as the lutein antioxidant supplementation trial (L.A.S.T) (4). This study evaluated the effects of lutein supplementation for one year in 90 veterans diagnosed with dry AMD. Supplementation with lutein in these subjects significantly increased the concentration of lutein in the macula. Improvements in visual function were also detected with lutein supplementation. Glare recovery, visual acuity, and contrast sensitivity were all improved. This study continues to build on clinical evidence that the dry form of AMD may be responsive to changes in nutrition. Cataracts A cataract is a natural clouding of the lens, the area of the eye responsible for focusing light and producing clear, sharp images. For most people, cataracts are a natural result of aging. Currently in the US, cataracts are the second leading cause of blindness in the elderly behind AMD. Lutein is the major carotenoid that has been identified in the human lens asn is thought to provide similar benefits to the leans that are seen in the retina. Two large epidemiological studies consisting of >70,000 women (age 45-71) and >30,000 men (age 45-75) compared the risk of cataract extraction to nutrient intake (5,6). Similar to AMD, a significant reduction in risk of cataract extraction was associated with lutein intakes of 6mg per day (20% reduction in risk). Besides cataract extraction, higher levels of lutein consumption have been associated with a decreased risk of cataract development and improvements in visual acuity and glare sensitivity in people with age-related cataracts. Lutein consumption The richest source of free lutein in the typical US diet are dark green leafy vegetables, with the highest concentration found in kale followed by spinach. The average daily lutein intake is low, average between 1-2 mg/day. Currently there is no recommendations of the dietary guidelines for Americans 2005 (9 servings of fruits and vegetables every day) you would consume between 4 and 8 mg of lutein a day (7). Epidemiological evidence, animal models, and clinical data have indicated levels of 6-10 mg a day may be necessary to realize the health benefits associated with lutein consumption. By continuing to increase our intake of lutein, we begin to ensure the optimal health of our eyes. References: Seddon et al.

According to a study published in the April 2004 edition of Optometry: The Journal of the American Optometric Association, the lutein antioxidant supplementation trial (LAST) concluded that visual function of study participants with symptoms of age-related macular degeneration (ARMD) improved with the intake of lutein alone or lutein together with other nutrients, such as antioxidants, vitamins, and minerals. Lutein and Zeaxanthin are fat soluble, yellow colored carotenoids found naturally in green leafy vegetables like spinach, egg yolks, corn, peaches and marigolds. Though these carotenoids are found in fatty tissues throughout the body, by far the highest concentration is found in the macula and retina of the eye. These fat-soluble antioxidants have been found to stop free radical reactions specifically the photo-reactive oxygen species that are particularly damaging to eye and skin tissues. What role do some of the other key ingredients play? Beta-Carotene is another antioxidant carotenoid found naturally in dark green and orange-yellow vegetables and fruit. Unlike Lutein however Beta-carotene can be converted to Vitamin A as needed by the body. Vitamin A is necessary for proper eye function and may reduce cataract formation. Bilberry, Green Tea, Ginkgo Biloba and Grapeseed extracts contribute compounds called Polyphenols and Anthocyanidins. These antioxidant compounds protect blood vessels that supply needed blood flow to the eyes and peripheral tissues. Rutin and the other Bioflavonoids stabilize the collagen matrix and maintain the integrity of the vital blood vessels that carry oxygen and nutrients to the eyes. Vitamins C and E are antioxidants that inhibit free radical damage and are used by the body to prevent some of the degenerative patterns related to the aging process. Vitamin C may protect the eye from UV rays that can damage the lens and cause cataracts. Taurine is a sulfur containing amino acid that is the most abundant amino acid in the retina of the eye and plays a role in healthy vision. Selenium and Zinc are minerals that help the body to produce the important cellular antioxidants Glutathione and SOD that protect eye tissue from oxidative damage.

Zeaxanthin with Lutein The clearly-seen benefits of advanced eye protection In the U.S. and other developed nations, the worst enemy of eyesight is not disease, it is the natural aging process. But even if the advance of years is unstoppable, new research shows that eyesight can be protected as we age. Two little-known carotenoids have been found to protect eyesight and combat the effects of aging upon the retina. Zeaxanthin and lutein, naturally found in many fruits and vegetables, form a natural filter on the retina, protecting the delicate photoreceptor cells from the damaging effects of blue-wave light and the UV radiation of sunlight. The two nutrients have also been found to be a natural antioxidant, further protecting the retina from the oxidation that arises from normal body functions as well as exposure to cigarette smoke, air pollutants, radiation, and environmental toxins. Source Naturals unites the benefits of both of these nutrients in ZEAXANTHIN WITH LUTEIN, offering one of the most advanced approaches to eye protection available.
Key to Healthy Vision
Vision-Specific Nutrients
Pigment Density A Harvard-led study found that eating lutein-rich foods five days per week meant subjects were eight times more likely to have healthy macular pigment density than those who consumed the same foods just once a month. Another study at the University of Florida found that diets rich in lutein and zeaxanthin could substantially (82%) protect the macula. A number of companies offer either lutein or zeaxanthin, Source Naturals combines the benefits of both, just as both are used in the eye.

Date:
August 02, 2005 03:52 PM
Benefits Benfotiamine raises the blood level of thiamine pyrophosphate (TPP), the biologically active co-enzyme of thiamine.4 Thiamine and its Co-enzyme, TPP Thiamine (vitamin B1) plays an essential part in the metabolism of glucose, through actions of it co-enzyme TPP (thiamine pyrophosphate). TPP is formed by the enzymatically-catalyzed addition of two phosphate groups donated by ATP to thiamine. TPP also goes by the name "thiamine diphosphate." In the cytoplasm of the cell, glucose, a 6-carbon sugar, is metabolized to pyruvic acid, which is converted into acetyl-CoA, otherwise known as "active acetate." Acetyl CoA enters the mitochondrion, where it serves as the starting substrate in the Kreb’s cycle (citric acid cycle). The Krebs cycle is the primary source of cellular metabolic energy. TPP, along with other co-enzymes, is essential for the removal of CO2 from pyruvic acid, which in turn is a key step in the conversion of pyruvic acid to acetyl CoA. CO2 removal from pyruvic acid is called "oxidative decarboxylation," and for this reason, TPP was originally referred to as "cocarboxylase." TPP is thus vital to the cell’s energy supply. Benfotiamine helps maintain healthy cells in the presence of blood glucose. Acting as a biochemical "super-thiamin," it does this through several different cellular mechanisms, as discussed below. Benfotiamine and Glucose Metabolism Benfotiamine normalizes cellular processes fueled by glucose metabolites. As long as glucose remains at normal levels, excess glucose metabolites do not accumulate within the cell. The bulk of the cell’s glucose supply is converted to pyruvic acid, which serves as substrate for production of acetyl CoA, the primary fuel for the Krebs cycle. Of the total amount of metabolic energy (in the form of ATP) released from food, the Krebs cycle generates about 90 percent.5 In the presence of elevated glucose levels, the electron transport chain, the final ATP-generating system in the mitochondrion, produces larger than normal amounts of the oxygen free radical "superoxide." This excess superoxide inhibits glyceraldehyde phosphate dehydrogenase (GAPDH), as key enzyme in the conversion of glucose to pyruvic acid, resulting in an excess of intermediate metabolites known as "triosephosphates." Increase triosephophate levels trigger several cellular mechanisms that result in potential damage to vascular tissue. Cells particularly vulnerable to this biochemical dysfunction are found in the retina, kidneys and nerves. Benfotiamine has been shown to block three of these mechanisms: the hexosamine pathway, the diaglycerol-protein kinease C pathway and the formation of Advanced Glycation End-poducts. As discussed below, benfotiamine does this by activating transketolase, a key thiamin-dependent enzyme.6 Benfotiamine stimulates tranketolase, a cellular enzyme essential for maintenance of normal glucose metabolic pathways.* Transketolase diverts the excess fructose-6-phosphate and glyceraldehydes-3-phosphate, (formed by the inhibition of GAPDH, as mentioned above), into production of pentose-5-phosphates and erythrose-4-phosphate and away from the damaging pathways. Benfotiamine activates transketolase activity in bovine aortic endothelial cells incubated in glucose.6 To test benfotiamine’s ability to counteract these metabolic abnormalities caused by elevated blood glucose, studies have been done in diabetic rats. Benfotiamine increases transketolase activity in the retinas of diabetic rats, while concomitantly decreasing hexosamine pathway activity, protein kinase C activity and AGE formation.6 Benfotiamine and Protein glycation Benfotiamine controls formation of Advanced Glycation End-products (AGEs). AGEs have an affinity for proteins such as collagen, the major structural protein in connective tissue. AGEs are formed through abnormal linkages between proteins and glucose. This occurs via a non-enzymatic glycosylation reaction similar to the "browning reaction" that takes place in stored food.7 At high glucose concentrations, glucose attaches to lysine, forming a Schiff base, which in turn forms "early glycosylation products." Once blood glucose levels return to normal levels, the amount of these early glycosylation products decreases, and they are not particularly harmful to most tissue proteins. On long-lived proteins such as collagen, however, early glycosylation products are chemically rearranged into the damaging Advanced Glycation End-products. AGE formation on the collagen in coronary arteries causes increased vascular permeability. This vessel "leakiness" allows for abnormal cross-linking between plasma proteins and other proteins in the vessel wall, comprising vascular function and potentially occluding the vessel lumen. A number of other potentially harmful events may also occur, including production of cytokines that further increase vascular permeability. Endothelin-1, a strong vasoconstrictor, is over produced, increasing the possibility of thrombosis and generation of oxygen free radicals is stimulated.8 It is vitally important to support normal glucose metabolic pathways so that formation of AGEs is minimized. Benfotiamine, in the test tube (in vitro) prevents AGE formation in endothelial cells cultured in high glucose by decreasing the glucose metabolites that produce AGEs.9 Endothelial cells make up the membranes that line the inner walls of organs and blood vessels. In a rat study comparing the effects of Benfotiamine with water-soluble thiamin, Benfotiamine inhibited AGE formation in diabetic rats while completely preventing formation of "glycooxidation products," which are toxic by products of chronic elevated blood glucose. AGE levels were not significantly altered by thiamin.10 Benfotiamine also normalized nerve function in the animals. After three months of administration, "nerve conduction velocity (NCV)," a measure of nerve function, was increased by both benfotiamine and thiamin; at six months, NCV was normalized by benfotiamine, whereas thiamin produced no further increases in this parameter. Dysfunctional glucose metabolic pathways leading to AGE formation occurs in endothelial cells of the kidneys. In a recent animal study, benfotiamine was administered to rats with elevated glucose levels. Benfotiamine increased transketolase activity in the kidney filtration system of these rats, while at the same time shifting triosephophates into the pentose pathway and preventing protein leakage.11 Safety Benfotiamine has an excellent tolerability profile and can be taken for long periods without adverse effects.3,12 The statements in this fact sheet have not been evaluated by the Food and Drug Administration.

July 27, 2005 11:54 AM
Benefits It has been well established that lutein is present in high concentrations in the retinal tissue of the human eye. However, a study was conducted in human volunteers to determine whether taking lutein in supplement form actually increased the density of the carotenoid pigments present in the macula. In this study of eight individuals, researchers estimated the density of the macular pigments prior to having each individual take 10 mg of lutein daily in supplement form for 12 weeks. Plasma lutein concentrations were measured at 4-week intervals. During the course of the study, plasma levels increased five-fold from pre-supplement measures. It was also shown that macular pigment density increased by an average of 5.3% after 4 weeks due to increased deposition of lutein in optical tissues.1 A second study compared the oral bioavailability of esterified lutein, the form in Best Lutein, versus non-esterified lutein in 18 human volunteers. Serum levels of lutein were measured at particular timepoints after consumption of a single dose of lutein. Researchers found that in these individuals, the lutein ester formulation was nearly 62% more bioavailable than non-esterified lutein, as determined by a higher mean area under the curve (AUC) and higher serum concentrations.2 A study was also conducted to investigate the possible role of specific nutrients in protecting the lens of the eye against aging, a risk factor for compromised visual function. The study was comprised of 376 individuals aged from 18 to 75. Of the nutrients measured, it was found that the lenses of individuals with higher concentrations of lutein and zeaxanthin showed less of an effect from the aging process. The investigators concluded that these carotenoids may play a protective role in supporting the maintenance of healthy vision.3 In addition, a double-blind placebo controlled trial was performed in ninety individuals who had signs of compromised visual function. Individuals were divided into three groups and received either 10 mg lutein, 10 mg lutein plus a multivitamin/multimineral formulation, or placebo for 12 months. In both the lutein and lutein plus other nutrients groups, improvements were seen in mean eye macular pigment optical density, visual acuity and contrast sensitivity. No improvements were noted in the placebo group.4 These results demonstrate lutein’s beneficial effect on maintaining healthy visual function. • Potent Antioxidant Protection* Most of the beneficial effects of lutein are ascribed to its potent free radical scavenging abilities. It is well-known that lutein is a carotenoid related to beta-carotene and possesses antioxidant activity against a number of reactive oxygen species.5 More direct evidence for the free radical scavenging activity of lutein is found in studies of its effects on human lens epithelial cells. Cell cultures were exposed to ultraviolet light after pretreatment with lutein or alpha-tocopherol. Both nutrients were found to reduce ultraviolet-induced damage to lens epithelial cells. However, lutein was shown to have significantly higher photoprotective activity than alpha-tocopherol6, demonstrating its potential as a high-powered antioxidant. A further review of the mechanisms of lutein in conferring a protective role reveals evidence for its antioxidant activity in various body tissues. Lutein has been shown to be an effective antioxidant in vitro as well as in experimental models of a number of body systems.7 • Diverse clinical benefits* Evidence from various experimental trials suggests that lutein may play a protective role on the circulatory and cardiovascular systems. Its antioxidant activity may also extend to the heart, skin, lungs and blood vessels, making it a nutrient with diverse clinical benefits. Lutein possesses the ability to promote the health of many body tissues.8 Safety Suggested Adult Use: One capsule daily, or as directed by a health care professional. Take with or without food.

Specific actions associated with Pycnogenol include:
PYCNOGENOL SPECIFICALLY TARGETS: SKIN AND ELASTICITY Testing has suggested that Pycnogenol flavonoids exhibited an anti-enzyme effect which prevented the break down of collagen and elastin, the very compounds which keep skin firm and inhibit the formation of wrinkles.7 TUMOR RELATED DISEASES Unquestionably, studies have shown that Pycnogenol has the ability to inhibit cellular mutations.8 The implications of this finding for anyone suffering from tumor related disease which originates from cellular malfunctions should not be underestimated. CARDIOVASCULAR CONDITIONS The potential of Pycnogenol to pr e vent cellular deterioration or uncontrolled growth is profound to say the least. Several investigations have shown that if it is taken on a daily basis, Pycnogenol benefits people suffering from cardiovascular diseases and breast tumors.9 In addition, double blind placebo controlled studies have indicated that patients suffering from circulatory insufficiencies and diseases of the lymph system showed significant improvement in pain control and vessel elasticity after taking these flavonoids.10 VISION Subsequent experiments concluded that the family of bioflavonoids contained in Pycnogenol is capable of improving night vision and initialing “a rapid and marked improvement of visual performances after glare in comparison with control group.”11 WATER RETENTION AND EDEMA Pycnogenol is particularly valuable for anyone who suffers from water retention and edema. Studies at the Institute of Physiology at the Bulgarian Academy of Sciences confirm that this biofl avonoid compound stabilized capillary walls, which decreased fluid leakage into tissues which causes swelling and pressure.12 WHAT PATHOLOGICAL CONDITIONS RESPOND TO PYCNOGENOL? The bioflavonoids found in Pycnogenol have been clinically indicated in the following pathological conditions:
PYCNOGENOL HAS THERAPEUTIC VALUE FOR THE FOLLOWING CONDITIONS:
PYCNOGENOL CAN CROSS THE BLOOD-BRAIN BARRIER One of the most significant advantages of this flavonoid compound is its ability to cross the blood-brain barrier. Consequently, it acts as an invaluable therapeutic agent in treating depression, chronic fatigue, insomnia or loss of memory. ANTI-ULCER FORMING PROPERTIES Other scientific tests have indicated that proanthocyanidins also posses anti-ulcer properties and may work to prevent the formation of undesirable chemicals in the stomach.13

Antioxidants By Ellen J. Kamhi, Ph. D. with Dorie Greenblatt Antioxidants. A term we hear often, but do we really pay attention to the enormous role these substances play in our systems? And what are they exactly anyhow? Where do they come from and how do they work? Antioxidants are a group of naturally occurring vitamins, minerals and enzymes found in plant foods. These vital substances help to protect our cells from free radicals, the culprits responsible for causing damage to our bodies very quickly. Free radicals are groups of unstable atoms looking to obtain electrons in order to become stable themselves. They can pull electrons off cell membranes, causing the cell membranes to have free radical activity as well. This unleashes a vicious cycle of cell destruction, known as a “free radical cascade.” Free radical damage is linked to a plethora of diseases. Luckily there are literally thousands of antioxidants to help us win the “free radical battle”. Antioxidants can be differentiated by their colors. Those of a red, orange or yellowish color fall into the group known as carotenoids, while those with a blue, purple, black color are from the phenolic family. Of course, there are also some yellow green phenolics too, like the polyphenols from Green Tea. The carotenoid group of antioxidants are fat-soluble and therefore offer protection for the fat containing parts of the body. This is especially useful in protecting our lipid containing cell membranes. These carotenoids hang out in our membranes, thereby protecting them from free radical damage. What’s even more important is the ability of carotenoids to enhance the activity of other fat-soluble antioxidants such as vitamins A, E and Co Q-10. Some of the best carotenoid sources are lycopene, curcumin and lutein. Lycopene, a red carotenoid derived from tomatoes, has been shown to contain strong protection capabilities against free radical damage. Curcumin, a yellow carotenoid from turmeric, displays a more protective antioxidant activity than that of Vitamin E or Vitamin A in protecting DNA breakdown (by free oxygen). It also serves as a potent anti-inflammatory agent. Lutein, another carotenoid antioxidant, is a primary component of the retina and macula areas of the eye. Lutein’s antioxidant properties may help protect the macula from light induced free radicals. Evidence shows it may help reduce the risk of age related macular degeneration as well. The phenolic groups are the water-soluble antioxidants. This group protects the blood, lymph and other bodily fluids, as well as the organs containing those fluids. Some of the best phenolic antioxidants are those found in Green Tea, particularly a group known as catechins. Catechins have proven to have immune- enhancing benefits. Another family of important phenolic antioxidants are those called anthocyanins. These too have proven to act to protect the immune system. Finally, we can’t forget one of the best-known water-soluble antioxidants: Vitamin C ! The need for antioxidants is widespread. We normally think of smokers as the primary group who would most benefit from antioxidants, but the truth is that anyone under stress is a prime candidate for taking antioxidants. In addition, anyone who carries a strenuous physical or mental work load or who exercises often needs the protection of antioxidants, since free radical levels are increased by an active metabolism. And, of course, those individuals who don’t consume enough fruits and vegetables in their diet should also consider using a well-rounded antioxidant formula. Nature’s Answer offers an outstanding selection of antioxidant formulas available in liquid and/or capsule form. These include Lycopene and Green Tea Extracts (liquid, softgel and vegetarian capsule), Bio-Flavonoids & Rose Hips (low organic alcohol liquid herbal extract) and Grape Seed Extract (vegetarian capsule). For a well-balanced potent antioxidant blend, try Antioxidant Supreme™, a standardized herbal extract formula containing the best of the carotenoid and phenolic antioxidants in one convenient vegetarian capsule. This formula, in particular, provides concentrated natural sources of antioxidants for “supreme” overall protection.

Diabetic Retinopathy and Ginkgo There is evidence to suggest that ginkgo extract may be beneficial for people with diabetes who risk damage to their optic nerves. Frequently, diabetes causes the membranes of capillaries located in the retina to thicken, there by obstructing blood flow and reducing vision. The retina is particularly susceptible to free radical damage. Apparently, ginkgo helps protect against that damage by reducing the amount of lipoperoxidation which can cause permanent vision loss. Laboratory studies using rats found that ginkgo may be able to prevent the impairment of visual function caused by free radicals, which can increase when blood sugar levels are high, and by inhibiting the formation of blood clots in the eye.

Circulatory System Enhancer An article by Frank Murray in the April 1989 issue of Better Nutrition says, “Dr. Huber and Kidd concur with other researchers that ginkgo biloba dilates the blood vessels, allowing greater blood flow to the tissues. It also provides better drainage of waste products, especially through arteries that have been partially blocked because of atherosclerosis.” The article goes on to discuss the fact that ginkgo also inhibits the clumping of blood platelets, which can contribute to heart and artery problems. When circulating platelets stick together on worn are as found on the walls of aging vessels, clots and blockages can form. Anytime this happens, heart attack and stroke are possibilities. Ginkgolides are unique twenty-carbon terpenes which inhibit PA F (platelet activating factor), which controls the formation of clots. PAF also plays an important role in other disorders such as asthma, shock, anaphylaxis, renal disease, graft rejection, CNS disorders and a number of inflammatory conditions. A Natural Vasodilator Ginkgo affects the lining of the blood vessels and acts to dilate them through a chemical constituent which stimulates the release of a certain factor. Tests have shown that ginkgo extract promotes better venous tone, which helps to clear the blood of toxic metabolites that collect when blood flow is diminished. Apparently Oriental herbalists used the ginkgo leaf for arterial circulatory problems. Blood vessels can constrict in cases of diabetes, Raynaud’s disease, gangrene, angina, and intermittent claudication. Ginkgo can help to relieve leg cramping by facilitating better circulation to the limbs. In addition, it increases the circulation of blood to the retina and can help to prevent macular degeneration. Concerning heart function, some studies suggest that ginkgo can help normalize heartbeat. Research has shown that ginkolide contained in ginkgo can be as effective as some pharmaceutical drugs in treating severely irregular heartbeats.8 Because ginkgo can effectively reduce blood cell clumping, it can help prevent some heart - related disorders such as congestive heart disease. Circulatory impairment is at “the heart” of cardiovascular disease and ginkgo specifically acts to enhance circulation. Se veral laboratory tests have found that ginkgo helps the heart contract more effectively after times of stress by reducing the formation of oxygen free radicals. This protective effect can help prevent damage to heart muscle which may become oxygen deprived.

Date:
June 24, 2005 05:34 PM
The average American’s life expectancy has risen dramatically over the last 100 years. Ideally those extra years will be quality ones. High levels of stress and exposure to environmental and dietary toxins can deplete our antioxidant stores, leaving us more susceptible to chronic health challenges. When we are young and healthy the body unleashes its own antioxidants, but as we age this internal antioxidant producing system declines and the body needs help. Free radicals cause oxidative stress, which is a major cause of accelerated aging. Source Naturals presents the science of RENEWAL ANTIOXIDANTS. This Bio-Aligned Formula™ is a significant advancement over other products currently available. No other formula provides the broad range of high potency, established and newly discovered water and fat-soluble antioxidants that RENEWAL ANTIOXIDANTS delivers. Bio-Aligned Antioxidant Support RENEWAL ANTIOXIDANTS™ supports multiple body systems with a balanced spectrum of plantioxidants™ (botanical extracts with unparalleled ability to combat free radicals), vitamins and specialty nutrients that have powerful antioxidant properties. Research suggests dietary antioxidants help balance and modulate free radical activity and help maintain structure and function of important components of cells such as lipids, proteins, and DNA. Oxygen is required by your cells to generate energy, but it also contributes to oxidative stress or free radical damage, which is one of the primary causes of age-related damage to cells and tissues. Free radicals are unpaired electrons that can damage cells and compromise the function of tissues and organs. Antioxidants make free radicals stable by providing them with an additional electron. Unfortunately, now the antioxidant is missing an electron so, ironically, it becomes a free radical, which requires another antioxidant to donate an electron. Because this process starts a cascade of free radicals, scientists strongly recommend a broad range of lipid and water soluble antioxidants to minimize this negative effect. No other antioxidant formula follows the science better than RENEWAL ANTIOXIDANTS to defend against the widest spectrum of destructive free radicals, including peroxyl, hydroxyl, and superoxide radicals, and singlet oxygen. Healthy Heart Antioxidants neutralize destructive free radicals and support cardiovascular health by halting the oxidation of cholesterol. Cholesterol is only harmful to us if it becomes oxidized. Oxidized cholesterol is an unstable molecule that damages arteries. RENEWAL ANTIOXIDANTS contains hearthealthy antioxidants including gamma E and tocotrienols, which are major lipid-soluble antioxidants that help maintain the integrity of cell membranes by preventing lipid oxidation. The formula includes hawthorn berry and grape seed, CoQ10, lycopene and other powerful antioxidants for heart support. Nourishing the Brain Antioxidants are critical for brain and nerve tissue because the brain is mostly composed of fats, which are very sensitive to free radical damage. Research has shown that stress can directly set in motion mechanisms that promote aging, which affects brain and nerve tissue. Ginkgo has been shown to increase memory performance and learning capacity as well as improve blood flow. It is also a free radical scavenger. RENEWAL ANTIOXIDANTS also contains DMAE, bilberry, CoQ10, grape seed, lipoic acid, vitamin B-2 and lutein for broad spectrum support. Liver Support Powerful antioxidants help minimize stress damage to liver cells and tissues, thereby supporting detoxification. N-acetyl cysteine is a powerful antioxidant. It is also a precursor to glutathione, a critical antioxidant and detoxifying substance produced in the liver. Silymarin is known for supporting the regeneration of the liver. Since the liver is prone to fat incursion, which makes it vulnerable to oxidative damage, the following fat soluble antioxidants provide critical protection: CoQ10, lipoic acid, ascorbyl palmitate, and gamma E. Immune Defense The immune system is unlike other body systems in that it is not a group of physical structures but a system of complex interactions involving many different organs. White blood cells generate enormous amounts of destructive free radicals in order to kill invading organisms. Vitamin C, a free radical scavenger, is concentrated in these white blood cells at a much higher level than in surrounding fluid. This extends their life and effectiveness by providing them with a built in defense mechanism against their own free radicals. RENEWAL ANTIOXIDANTS provides water and fat-soluble vitamin C (ascorbyl palmitate and ascorbic acid) along with vitamin A, beta carotene, CoQ10, lipoic acid, quercetin, selenium, gamma vitamin E, tocotrienols, zinc and turmeric, for added immune defense. Skin & Connective Tissue Skin is rich in lipids, proteins, and DNA, which are extremely sensitive to oxidation. Age-related changes due to oxidation, loss of elastic fibers and thickening of collagen fibers, cause skin to become fragile and less supple. A broad array of antioxidants protects skin and helps maintain its structure and tone. These include beta carotene, vitamin C, vitamin E, grape seed, zinc, amla (Phylanthus emblica), quercetin, DMAE, manganese and myricetin. Amla is a very effective herbal tonic. It is rich in polyphenols and vitamin C. Clear Vision Eye tissue is particularly prone to the effect of free radicals. Vision involves light being focused through the lens onto the retina. The macula, or center of the retina, receives the most light. However, sunlight is a powerful free radical generator. Lutein, a potent, fatsoluble antioxidant concentrated in the macula, helps maintain the integrity of the macula and the blood vessels that supply the macular region. The eye also has aqueous tissue that is better protected by water-soluble antioxidants, such as bilberry and grape seed. RENEWAL ANTIOXIDANTS provides these ingredients, along with lycopene, zeaxanthin, lipoic acid, vitamin A, beta carotene and ascorbyl palmitate to support healthy eyes. Energy Generation Mitochondria, the tiny energy factories within the cells, are the major source of free radicals produced by our own bodies. These components of cells produce ATP (the energy molecule) and provide energy for all cellular activity; therefore, antioxidants are crucial to keep the levels of oxidants they produce in check. RENEWAL ANTIOXIDANTS provides the antioxidant power of green tea, lipoic acid, zinc, vitamin B-2, CoQ10 and Mega H-, a source of electron rich hydrogen ions. Coenzyme Q10 is fat-soluble and its primary functions include activity as an antioxidant and as a cofactor in many metabolic pathways, particularly in the production of ATP in oxidative respiration. DNA Protection DNA, the blueprint for all molecules in the body, can be altered or damaged by oxidation. Protecting DNA is important for optimal health of all cells and tissues. According to invitro research, certain compounds, such as curcumin (from turmeric) and quercetin, can directly protect against strand-breakage and base oxidation. RENEWAL ANTIOXIDANTS contains these ingredients along with rosemary, pomegranate, raspberry, blueberry leaf, and carnosine. In in-vitro studies, L-carnosine reduced glycation, a process in which DNA and protein are damaged by glucose. Living Longer, Living Better Strategies for Wellness

Vision Quest by Phyllis D. Light, RH Energy Times, February 11, 2004 Since your eyes are in constant use every day, exposed to the damaging energy of sunlight and pollutants that waft through the air, these delicate orbs are often in danger of wearing out. To keep this vital part of your anatomy functioning as you age, you have to feed and care for your eyes properly. Otherwise, you are in real danger of losing your vision and independence. Your vision may be in danger. Experts estimate that 8 million Americans over the age of 55 are at serious risk of blindness linked to a condition called age-related macular degeneration (AMD). AMD can wipe out your central vision and is the primary cause of blindness in Western society. While AMD causes no pain, it blurs the sharp, central vision necessary for driving, reading and other activities where you need to see either up close or straight ahead. During AMD, the macula, the part of the eye that allows you to pick out fine detail, is destroyed. The macula sits at the center of your retina, the nerve center at the back of your eye that senses light and sends optic signals to the brain. Age is not the only risk factor for AMD. Scientists have isolated a genetic defect that can lead to some forms of macular degeneration (Nature Genetics 2001; 27:89-93). Smoking and excessive exposure to sunlight are other hazards best avoided if you want to save your sight. In many cases, AMD progresses so slowly that victims of this condition don't even notice that their vision is deteriorating until much of it is irrevocably gone. Dry and Wet AMD Wet AMD occurs when blood vessels in back of the retina start to overgrow and leak blood. As this occurs, blood and other fluids push on the macula and quickly damage its sensitive nerve endings. When wet AMD occurs, you lose your central vision rapidly. If straight lines appear wavy to you, you may be suffering from wet AMD. If you notice this or other unusual vision changes, contact an eye care specialist as soon as possible. You need what is called a comprehensive dilated eye exam that can uncover signs of AMD. Dry AMD strikes the eye when light-sensitive cells in the macula slowly deteriorate, gradually blurring central vision in the affected eye. As dry AMD progresses, a blurry spot in the center of your vision may appear. Eventually, as more of the macula becomes dysfunctional, the central vision in the eye can gradually disappear. The most common sign of dry AMD is slightly blurry vision. This can make it hard to recognize faces and also make it harder to read without very bright light. Dry AMD generally attacks both eyes, but vision can be lost in one eye while the other eye stays normal. In the early stages of dry AMD, drusen, yellow deposits that gather under the retina, may form. Dry AMD progresses in three stages:
Vitamins and Minerals for AMD Fortunately, scientists have found ways to combat AMD: An analysis of a study called the national Age-Related Eye Disease Study (AREDS) shows that more than 300,000 Americans could avoid losing their sight to AMD if they took daily supplements of antioxidant nutrients and zinc. This conclusion, reached by scientists at Johns Hopkins' Wilmer Eye Institute, is based on research involving more than 4,500 adults suffering various stages of AMD. The study demonstrated that people who already had some AMD could lower their risk of the more advanced form of this condition by 25% when they took vitamin C, natural vitamin E and beta carotene along with zinc. Those suffering from advanced AMD lowered their chances of losing vision by about 19%. (Supplements did not affect the risk of cataracts or the chances of some vision loss for people in the early stages of AMD.) " Without treatment to reduce their risk, we estimate that 1.3 million adults would develop the advanced stage of AMD," says Neil M. Bressler, MD, professor of ophthalmology at Johns Hopkins and author of the current study, published in Archives of Ophthalmology (11/03). According to Dr. Bressler and the other researchers, people who now have intermediate AMD (some vision loss) in one eye have about a 1 in 16 chance of having their vision deteriorate until they have advanced AMD. They also calculate that about 1 in 4 of those with intermediate AMD in both eyes and 43% of those with advanced AMD in one eye will develop advanced AMD in five years without treatment. In their view, older people at risk of AMD blindness should take daily supplements of 500 milligrams of vitamin C, 400 milligrams of natural vitamin E, 15 milligrams of beta carotene, 80 milligrams of zinc as zinc oxide and 2 milligrams of copper as cupric oxide. Evidence also exists that a diet which is high in fat can cause AMD to progress to an advanced stage. The exceptions: The healthy fats found in fish and nuts (Archives of Ophthalmology 2003; 121:1728-37). Lutein Protection Oddly enough, some of the same pigments that color vegetables and other foods also color your eyes. And scientists believe that those pigments, which are classified as carotenoids, help protect the eyes by helping them fight off the negative effects of caustic molecules called free radicals. Free radicals are formed when the energy from sunlight strikes the eyes and disrupts the composition of natural chemicals found there. When scientists compared healthy eyes with eyes suffering from AMD, they found that AMD eyes contained lower levels of lutein and zeaxanthin, carotenoid pigments contained in egg yolk, spinach, broccoli and other dark green vegetables (Ophthalmology 2003; 109:1780). Furthermore, they found that levels of these chemicals generally decline as you grow older. " This research is a major step toward large-scale clinical studies to prove the extent to which lutein and zeaxanthin protect against age-related macular degeneration," says Paul S. Bernstein, MD, PhD, at the University of Utah School of Medicine at Salt Lake. "We know that these carotenoids are specifically concentrated in the macula of the human eye." Dr. Bernstein adds that, as you age, taking supplements containing lutein and other antioxidants may lower your AMD risk. In his investigation, people with AMD who did not take lutein had one-third less lutein in their eyes than older people whose vision was normal. Avoiding Cataracts Another eyesight hazard is cataracts, in which the eye's lens-the part that focuses incoming light onto the retina-becomes cloudy. Cataracts form when the proteins found in the normally clear lens become damaged; signs include progressively blurred vision (especially outdoors), focusing problems, seeing streaks of light from headlights and stoplights, and colors that look faded. Cataract is the leading cause of blindness worldwide, according to the World Health Organization. One of every six Americans 40 and older suffers from some degree of cataract; it affects half of all Americans who reach age 80. Nuclear cataracts, the most common form of this disorder, develop in the center of the lens and tend to grow slowly. Cataracts may also develop at the back of the lens; this form is linked to eye trauma and long-term use of certain medications, including steroids. Like AMD, cataracts become more common as people age. Up to 40% of individuals between the ages of 75 and 85 have them, compared with only 5% to 10% of those folks under the age of 65. And like AMD, sunlight exposure and smoking increase the risk of developing cataracts, as does the presence of diabetes. Lutein and zeaxanthin, the carotenoids that are so plentiful in the macula, are also found in the lens (although in lower concentrations), leading many researchers to believe that these nutrients may help drop your risk of cataract development. Early studies indicate that an increased intake of lutein and zeaxanthin reduces one's chances of needing cataract surgery, the most common surgery in the United States (American Journal of Clinical Nutrition 1999; 70(4):509-16; 517-24). Antioxidants and the Lens Scientists believe that free-radical damage is a leading cause of cataracts, and so it isn't surprising that antioxidants have proved useful in preventing this problem. Almost 500 women filled out diet questionnaires as part of a very large research effort called the Nurses' Health Study; those who had taken vitamin C supplements for 10 years or longer enjoyed the lowest rates of nuclear cataracts (Archives of Ophthalmology 2001; 119:1009-19). So the answer to lowering your risk of eye problems is clear, whether you are already in your mature years or plan to be someday: Lead a healthy, eye-friendly lifestyle, eating a diet filled with colorful fruits and vegetables. Take frequent walks and jogs around the block. And yes, when you kick back and take your just-as-frequent doses of antioxidant supplements, you're allowed to take your sunglasses off and see the world clearly.

The A Team by Gregory Meade Energy Times, October 11, 2004 Want the A Team playing to improve your health? When you accumulate enough antioxidants to help you attack the molecular marauders out to mar your well-being, you improve your chances of avoiding illness. Nowadays you hear plenty of talk about the benefits of antioxidant nutrients. Antioxidants are the ammunition the body uses to fight off internal damage. They offer the body the means to fight against disease but, at the same time, your body must be in the position to use them optimally. That means getting enough sleep, consistently exercising and avoiding overly processed foods. Those lifestyle habits allow your body to garner its resources and effectively implement antioxidants in its quest for well-being. Your body has a love-hate relationship with oxidation: Can't live without it, often has trouble living with it. For instance, the production of energy in your cells requires oxidation. But the byproducts of that process, problematic molecules called free radicals, have to be chemically changed or eliminated to avoid the damage that results when they interact with other parts of the cell. Left unchecked, these molecular troublemakers can wreak havoc, oxidizing and punching holes in cell membranes and damaging other structures they contact. Antioxidant nutrients are used to defend against oxidation, quell these harmful destroyers and limit the potential harm they can cause. For a quick glimpse of one of your basic antioxidant defenses, look in the mirror. The color in your eyes represents antioxidant protection against oxidative injury from the ultraviolet rays in sunlight. Sunlight's energy sets loose free radicals every time it enters the lenses in your eyes. Pigments absorb this radiation and, in most cases, render it harmless. As part of your vision's defenses, two of the antioxidant pigments in your food, lutein and zeaxanthin, are deposited by your body in certain areas of your eyes-in a section called the macula as well as the lens (BJ Opthalmol 1998; 82:907-10). Lutein and zeaxanthin are classified as carotenoids, chemical relatives of beta carotene, the antioxidant pigment that makes carrots orange, and lycopene, the anticancer red coloring found in tomatoes. These fat-soluble nutrients are also present in algae. In both your eyes and plants, these nutrients absorb the destructive ultraviolet rays that give birth to free radicals. Blindness Protection Studies show that consuming large amounts of these pigments lowers your risk of a common form of blindness called age-related macular degeneration (ARMD) and drops your chances of age-related cataracts. (More than 30 million people worldwide suffer from ARMD, and cataracts is the leading cause of blindness across the globe.) When the sun's rays enter the eye, lutein and zeaxanthin absorb and filter out dangerous radiation before it can injure the macula. The macula is the central part of the retina that allows us to see very fine detail. Otherwise, over time, as the macula deteriorates, our vision worsens. In addition, some researchers believe these nutrients help lower your chances of cancer. Lutein and zeaxanthin are found in spinach, Brussels sprouts, corn, collard greens, green beans, egg yolks, broccoli, cabbage, kale, lettuce, kiwi and honeydew melons. The petals of yellow flowers like marigolds and nettles are also rich in these antioxidant nutrients. Broccoli Protection You can also increase your chances of better sight as you age by consuming sulphoraphane, an antioxidant found in broccoli. Researchers at Johns Hopkins University have found that sulphoraphane takes part in the body's efforts to shield eye cells from free radicals generated by ultraviolet light (Proc Natl Acad Sci 2004; 101(28):10446-51). The researchers who performed this study believe that unlike the antioxidant nutrients vitamin C and natural vitamin E, sulphoraphane acts as an "indirect" antioxidant. That means that while those two vitamins are used by the body to directly defuse the harmful oxidative force of free radicals (and then must be replaced or regenerated in the cells), sulphoraphane acts indirectly, boosting the body's immunity defenses. Because of that indirect action, researchers point out, sulphoraphane lasts longer in the body and may produce a more profound, long-term antioxidant effect. In other laboratory tests, researchers have discovered that sulphoraphane can kill Helicobacter pylori, a bacterium recognized 20 years ago as the cause of debilitating stomach ulcers and often-fatal stomach cancers (Proc Natl Acad of Sci 5/28/02). This research shows that sulphoraphane is even effective against antibiotic-resistant Helicobacter. Adding to its benefits, sulphoraphane can help kill bacteria both inside and outside stomach cells; when this bacteria hides inside of cells it is particularly difficult to fight. " We've known for some time that sulforaphane had modest antibiotic activity," says Jed Fahey, a plant physiologist at Hopkins. "However, its potency against Helicobacter, even those strains resistant to conventional antibiotics, was a pleasant surprise." Looking for Mr. Good Diet For the biggest bang for your antioxidant buck, combine antioxidants with good lifestyle habits. A laboratory study of the heart-healthy effects of taking supplements of the antioxidant vitamins C and natural E along with L-arginine (an amino acid) found that exercise magnifies benefits (Proceedings of the National Academy of Sciences 5/24/04, online). The scientists who performed this study recommend exercise along with antioxidants to boost your nutritional advantage. The box score shows that when playing with the A Team you've got the best chance of hitting an antioxidant home run.

Diabetes by , February 5, 2002 Lack of exercise and being overweight boosts your chances of developing diabetes. So, as America's epidemic of obesity grows, the number of people afflicted with the condition called type II diabetes is expected to soar. If you follow the typical US pattern of not getting enough exercise while indulging in a diet of too many calories from cookies, cakes, fast food and saturated fat as your waistline gradually expands, your chances of encountering this health menace grow every day. According to the most recent estimate by health researchers, "more than half of all US adults are considered overweight or obese"(JAMA, 10/27/99). Those same researchers, who examined the health history and weights of more than 16,000 Americans, confirmed a fact well-understood by health practitioners who understand the chemistry of blood sugar: being overweight greatly increases your chances of not only diabetes but also high blood pressure, gall bladder disease, coronary heart disease, high cholesterol and arthritis. (If you suffer or think you suffer from diabetes, or any of these conditions, consult a knowledgeable health practitioner.) Insulin Insurrection While Type I diabetes is a relatively infrequent disease that often strikes kids, Type II diabetes is a much more widespread (and increasing) health problem experienced by 9 out of 10 adults with what is now called adult-onset diabetes. The popular image of someone with diabetes is, ironically, often of someone who is suffering with Type I. In simplistic terms, Type I diabetes occurs when your pancreas stops producing insulin, a hormone-like substance that, among its several tasks, helps deliver sugar from the bloodstream into the body's cells. When your body is functioning normally, insulin helps steady blood sugar levels and keeps tissues fed with nutrients. People with Type I diabetes often have to inject themselves with insulin. Otherwise, a lack of insulin causes dangerously increased blood sugar levels, cellular damage to blood vessels and nerves plus a high risk of heart attack, blindness, kidney failure and serious damage to your extremities that may, in the long-term, lead to amputation. Insulin Resistance On the other hand, someone beginning to suffer Type II diabetes usually has plenty of insulin being produced by the pancreas, but may be insulin resistant: for a variety of physiological reasons, the hormone is unable to do its job. That allows blood glucose to reach levels where it can wreak metabolic havoc. When you gain weight, drastically increase the amount of your bodyfat and lead a sedentary, couch potato existence without engaging in very much exercise, you boost your risk of becoming insulin resistant. Consequently you also boost the chances of eventually suffering Type II diabetes. However, a consistent exercise program (and losing weight) can alleviate or moderate some of the blood sugar problems brought on by diabetes or insulin resistance. When you exercise, your working muscles may take in more glucose from the bloodstream and stabilize your blood sugar level. That is one reason physical exercise helps to modify your body's response to blood sugar. (Of course, if you have diabetes or have not exercised in a long time, be sure to consult your health practitioner before engaging in strenuous physical activity.) Supplemental Help One of the most useful supplements employed to help control diabetes is chromium, a mineral that plays an integral role in the body's metabolism of sugar. In the Natural Health Bible, Steven Bratman, MD, and David Kroll, PhD, discuss a study in China of 180 people with Type II diabetes. In that study, those who took chromium enjoyed better blood sugar levels than the people who took no supplements (Diabetes 46(11): 1786-1791, 1997). In addition, a double-blind study of chromium found that the supplement could reduce the necessary oral medication by more than half in many cases (Harefuah 125(5-6): 142-145, 1993). In this study, women seemed to benefit from chromium more than men. Relief with Alpha Lipoic Acid Alpha lipoic acid, an antioxidant nutrient, helps defend nerve cells against painful damage-a condition called neuropathy-that can result from diabetes. Consequently, in Germany, doctors have been prescribing lipoic acid to people with diabetes for more than two decades. According to Dr. Bratman and Dr. Kroll, studies show that lipoic acid may be particularly helpful when taken with gamma-linolenic acid (GLA), a fatty acid found in evening primrose oil and borage oil. Studies of GLA have found that this fat can soothe numbness and pain and slow nerve injuries (Diabetes Care 16(1):8-15, 1993). Taken together, GLA and lipoic acid may synergistically improve nerve function (Diabetologia 41(4): 390-399, 1998). Blood sugar control may also improve. Healthy Mouth Two signs that you may be suffering diabetes are excessive thirst and a dry mouth. This missing liquid, especially in the mouth when the flow of saliva slows, can lead to a lack of lactoferrin, a naturally-occurring protein that fights infection in the mouth by binding iron (Jrnl of Diab Comp 7, 57-62). Lactoferrin's iron-binding ability destroys harmful micro-organisms like bacteria. In addition, lactoferrin stimulates the body's production of a substance called secretory IgA, which keeps disease-causing organisms out of the body and helps stabilize blood sugar (colostrum also produces this effect). Spice Health Fenugreek, a spice, has had long use as a medicine and food ingredient in the Middle East and Asia. And now modern science has begun to accumulate evidence supporting its traditional use: Several studies have shown that this seed can benefit blood sugar levels and keep blood cholesterol down. In laboratory animals, researchers found that fenugreek kept blood sugar levels under control and also increased HDL (good cholesterol) while dropping triglycerides, blood fats that increase the risk of heart disease (Eur Jrnl Clin Nut 44 (1990):301-306). Fortuitously, studies on people have supported fenugreek's benefits. In people with Type I diabetes, studies show that fasting blood sugar levels were reduced and glucose tolerance tests (measures of how well the body handles sugar) were closer to normal (Eur Jrnl Clin Nut 42 (1988):51-54). Bilberry for Eye Health Retinopathy, eye damage resulting from diabetes, is a serious complication of this disease and can cause blindness. Bilberry, a botanical that has been used as a folk treatment for eye health for centuries, may be able to lower the risk of this kind of vision destruction. Bilberry, a dark berry that grows in Europe, has been shown in a collection of laboratory tests to hold down blood sugar levels (Quart Jrnl Cr Drug Res 17(1979):139-196). Bilberry has traditionally been used to protect eyesight. According to the Encyclopedia of Natural Medicine (Prima), natural substances called flavonoids, found in bilberry, "have been shown to increase intracellular vitamin C levels, decrease the leakiness and breakage of small blood vessels, prevent easy bruising and exert potent antioxidant effects." Apparently, the body uses these flavonoids to protect the eyes' blood vessels and to keep the retina (central part of the eye crucial to preserving sight) functioning normally (Arch Med Int 37 (1985):29-35). Consequently, bilberry has been used by health practitioners in France to treat diabetic retinopathy ever since the 1940s. Diabetes Research As medical researchers look more closely into how insulin functions throughout the body, much more light will be thrown on how supplemental nutrients and your diet interact to promote the healthiest blood sugar levels. But, today, what we already know about how the body functions can help you: a low-fat, high fiber diet, moderate, consistent exercise and healthy doses of insulin-friendly supplements may help keep your blood sugar under control. And keep those pounds from accumulating around your waist. That way, you can keep from singing that nasty old, down and dirty, blood sugar, syncopated ragtime blues.

Date:
June 09, 2005 09:27 AM
In 1912, Casimir Funk coined the term 'vitamine' to refer to a 'vital factor' he proposed was an essential component present in foods. His conjecture dovetailed with other research, leading to the isolation in the 1930's and 40's of the compounds we now call vitamins. Vitamins are chemical substances which play a variety of roles in the human body. They are core components of any nutritional supplementation program. While many people are aware of vitamins as necessary substances for good nutrition, few have a grasp of the extraordinary complexity of the roles they play in our bodies. As you'll see below, vitamins are involved in trillions of biochemical interactions every minute to keep us alive and functioning. For example, B-vitamins are converted into coenzymes which are directly necessary for the production of ATP energy from food, a process that goes on continuously in every cell in the body and which in turn fuels myriad physiological events such as muscle contraction, brain activity or tissue repair. Source Naturals offers a full line of vitamins in bioactive forms, allowing you to tailor a nutritional supplementation plan to your individual needs.
VITAMIN A and CAROTENOIDS Vitamin A Vitamin A is a generic term for a class of fat-soluble substances called retinoids, which can either be consumed preformed or synthesized by the liver from plant pigments called carotenoids (see 'Carotenoids', below). An essential nutrient, vitamin A is perhaps best known for its role in vision. The outer segments of the rods, a type of light-sensitive cell in the retina of the eye, contain a pigment called rhodopsin (or 'visual purple') that mediates vision in dim light. Cone cells mediate color vision via three additional pigments. Both rods and cones are surrounded by pigmented epithelial cells that store vitamin A. Rhodopsin is formed from a protein called opsin and a vitamin A-dependent compound called 11-cis retinal. As light strikes the rods and cones it is absorbed by the pigment molecules, and retinal is split off from opsin. This chemical change allows an electrical impulse to be sent to the optic nerve and thus to the brain. The pigment must then be regenerated from opsin and retinal. Repeated small losses of retinal during this process require a constant replenishment of vitamin A to the eyes. Vitamin A also plays an extremely important role in epithelial cell differentiation. Cell differentiation is the process by which a cell undergoes a change to a specialized cell type, allowing it to perform particular functions in the body. It is not yet understood precisely how vitamin A is involved in this process. One hypothesis is that it directly affects gene expression through its interaction with chromatin, a complex of DNA, RNA and protein in the cell nucleus. These interactions affect the process of transcription of DNA to messenger RNA, leading to synthesis of a specific group of cellular proteins. Each one of us carries in our DNA a unique genetic blueprint. This genetic material is the same in every cell of our bodies. It is only because of this mysterious and magical process of differentiation that we have specialized cell types - and therefore eyes, ears, lungs and hearts. Vitamin A is necessary, either directly or indirectly, for the healthy growth and functioning of many of our tissues and organ systems, including the eyes, the skin, the bones, the reproductive system, and the natural defenses. It is not yet known whether this requirement is due to the role of vitamin A in cell differentiation or whether there are other physiological processes for which vitamin A is essential. Carotenoids Vitamin A is related to a class of nutrients called carotenoids, including alpha and beta carotene, lycopene and lutein. Carotenoids are botanical pigments whose colors range from red to orange to yellow. Some carotenoids, particularly beta carotene, can be converted into vitamin A predominantly in the intestinal mucosa and to some extent in the liver. Carotenoids are completely non-toxic; their conversion into vitamin A is well-regulated by the body, making them extremely safe sources of this essential nutrient. In addition to their role as safe sources of vitamin A, carotenoids are powerful nutrients in their own right. Their primary claim to fame is their powerful antioxidant action, particularly against singlet oxygen. Singlet oxygen is an 'excited' ion of oxygen which, while not technically a free radical, is nonetheless highly reactive. It causes 'oxidative' reactions which can impair or destroy membranes, enzymes and DNA. It can also lead to the formation of free radicals which can cause additional damage. Certain carotenoids such as beta carotene, because of their chemical structure, can neutralize singlet oxygen by absorbing its extra energy and dissipating it throughout the carotenoid molecule, releasing the energy as heat and converting the singlet oxygen back to 'normal' oxygen. One molecule of beta carotene can quench up to 1000 molecules of singlet oxygen. In addition to their role as singlet oxygen quenchers, carotenes provide antioxidant protection against free radicals as well. In nature, they protect plants from photo-oxidative reactions; in humans, certain carotenoids, notably beta carotene, may help protect the skin from such reactions. Other carotenoids may provide more localized protection to particular organs. Lutein and zeaxanthin, for example, are selectively concentrated in the retina of the eye. Along with vitamins C and E, carotenes are among the most important nutrient antioxidants in the human body.

Date:
June 02, 2005 01:39 PM
One of the more surprising discoveries of modern nutritional science is that the very pigments which give brilliant color to our fruits and vegetables are powerful nutrients which can protect us from the rigors of time and environment. Lutein is one of the most recent discoveries in this field. In our diets, it’s found most abundantly in dark green leafy vegetables such as spinach, collards and kale. Like beta-carotene, lutein is a powerful antioxidant which studies show can contribute to the protection of cells. But the most promising application of lutein may be its beneficial influence on the eyes, particularly in regard to macular degeneration. Source Naturals LUTEIN is a concentrated source of this important natural nutrient. Like the beta-carotene that makes carrots orange and the lycopene that makes tomatoes red, lutein is a carotenoid. It is the pigment that makes corn yellow, and gives marigolds their brilliant golden color. One of the most interesting aspects of the way carotenoids interact with the human body – beyond their broad spectrum antioxidant activity – is their tendency to be “organ specific.” Different carotenoids have an affinity for different organs in the body. In the case of lutein, it is found concentrated in the structure of our eyes. Vision and Macular Health The process of vision involves light being focused through the lens and onto the retina, the paper-thin tissue lining the back of the eyeball. The central portion of the retina, called the macula, receives the most light. Its millions of cells produce the sharp vision needed to read and see objects clearly. With age, tiny blood vessels grow over this area, causing a gradual distortion and loss of vision. This degeneration of the macular region of the retina is the leading cause of irreversible visual impairment in the USA today. It affects almost 20% of people past the age of 65. Research has shown that these people have lower than normal amounts of macular pigment, which suggests the protective role played by these pigments. In fact, the latest research suggests that low levels of macular pigment is a cause, rather than a result, of macular deterioration. Lutein – The Eyes Have It Lutein and another carotenoid called zeaxanthin are the most dominant pigments in the macular region of the retina. (Source Naturals LUTEIN contains 5-7% zeaxanthin.) Their antioxidant properties help maintain the integrity of the blood vessels that supply the macular region of the retina: providing protection from photo-oxidation, the result of light striking the fatty acids in the retina. It seems that lutein is particularly active against the blue part of the spectrum, which can be the most damaging to our eyes. One study using lutein supplements resulted in a 15% increase in macular pigment levels after 72 days. In another study, people who consumed the equivalent of 6 mg of lutein per day were 40% less likely to experience macular problems. Another study using sets of identical twins demonstrated that macular lutein concentrations were related to dietary lutein. After consumption, lutein is found in significant quantities in blood serum, suggesting high bioavailability. Our Connection with Plants In this era of biochemistry, we’re rediscovering our vital connection with plant life. Although research into phytonutrients is relatively new, many plant compounds are being found in significant concentrations in the human body. Their presence in our blood serum, organs, and mothers’ milk suggests they play an important role in our body chemistry, and perhaps explains why we’ve appreciated them as foods throughout history. Like many carotenoids, lutein has evolved as an integral part of human biochemistry, with many benefits to our well-being. Since mammals cannot synthesize it, lutein must be obtained from the diet. Source Naturals LUTEIN is extracted from specially grown marigold flowers high in Lutein, and purified by an exclusive patented process. So the next time you bathe your eyes in a golden bouquet of marigolds, remember their beauty really is in the eye of the beholder.

Date:
June 01, 2005 11:59 AM
In today’s society, “fat” has become a bad word. Our quest for good health has influenced many of us to drastically reduce our intake of fatty foods. But this dietary change has brought unintended consequences. As we’ve cut back on unhealthy saturated fats, we’ve also reduced certain “good” fats essential to our well-being. Few people realize how important fats are to a healthy brain. In fact, our brains are primarily fat, 60% by dry weight! And DHA, the most plentiful fatty acid in the brain, is crucial to brain health, from infancy to old age. Now DHA is available in a vegetarian source compatible with today’s trimmed-down lifestyle. Introducing: Source Naturals NEUROMINS DHA. The Building Block of the Brain DHA is shorthand for docosahexaenoic acid. This omega-3 long chain fatty acid is the primary building block of the brain and retina of the eye. The brain is 60% fat, and DHA is the most abundant fatty acid in the brain, comprising 25-35%. DHA is found in even greater concentrations - 50- 60% - in the retina. DHA is critical for infant development. Compelling research links DHA to the rapid cerebral and eye development that occurs during pregnancy and in the first few months after birth. DHA passes through the placenta to the fetus during pregnancy, and to the nursing baby through breast milk. Optimal levels of DHA in the bloodstream of pregnant women and the breast milk of nursing mothers are crucial to babies. In fact, DHA’s presence in breast milk may explain why breast-fed babies have demonstrable IQ advantages over babies fed formula without DHA. An emerging body of research led an expert committee of the U.N.’s Food and Agriculture Organization/World Health Organization to recommend that DHA be included in infant formulas at levels comparable to those of mothers’ milk. Yet DHA levels in the breast milk of American women rank among the lowest in the world, and DHA is still not available in U.S. infant formulas. Supporting a Healthy Nervous System DHA’s benefits are not limited to infant development. Supplementation may be helpful to anyone with a low DHA intake, especially for supporting a healthy nervous system. DHA has been associated with optimal memory function, visual acuity, and maintaining a positive mental state. DHA is an integral component of all membranes with electrical activity. The cells in our brain, retina and other parts of the nervous system have a complex network of connecting arms that transport electrical messages throughout the body. DHA’s presence in nerve cell membranes is critical because this is where messages are transmitted. It is at the membrane that nerve cells generate the electrical impulses that are the basis of all communication in the nervous system. Without the necessary fatty acids, this communication system can break down or become less effective. DHA supplementation may be especially important as we grow older. The body’s ability to synthesize DHA, which is very limited in all human beings, may decline even further with age. Research suggests that aging interferes with the activity of delta-6-desaturase, the enzyme involved in the conversion of omega-3 fatty acids into DHA. Elderly people with inadequate or DHAdeficient diets may benefit from a supplementary source of DHA. Insufficient in Today’s Diet Because human beings cannot adequately synthesize DHA, most of it is obtained from our diets. The richest sources are red meats, animal organs and eggs - among the first foods to be eliminated by people concerned about fat intake. Today, the average American is getting less DHA from food, and vegetarians, vegans, and people on lowfat diets are especially at risk. Fish are a good dietary source, but must be eaten several times a week to provide enough DHA for optimal brain function. Fish obtain their DHA from microalgae – the nutritional basis of NEUROMINS. Neuromins: a Pure, Safe Source Source Naturals DHA is obtained from NEUROMINS, a dietary supplement derived from algae in a base of sunflower oil. NEUROMINS DHA is a highly purified form of DHA, produced under tightly controlled manufacturing conditions. Unlike fish oil, which used to be the main supplemental source of DHA, NEUROMINS does not contain the fatty acid eicosapentaenoic acid (EPA), which is not recommended for infants or children. Source Naturals NEUROMINS DHA is available in bottles of 30, 60 and 120 softgels, in both 100 and 200 mg dosages. Pure, safe DHA in the 200 mg dosage may be especially beneficial for pregnant or nursing women.

It is an integral component of all membranes with electrical activity, including the cells in our brain and nervous system. ARCTICPURE DHA contains 50% DHA, or 250 mg, in each softgel. ARCTICPURE EPA™ EPA is another omega-3 fatty acid, which has been associated with many potential health benefits. Epidemiological and animal studies have shown that EPA can support a healthy cardiovascular system. It is important for healthy skin and is a precursor of prostaglandins, thromboxanes and leukotrienes. These chemical mediators help regulate a variety of physiological processes, including blood pressure and blood clotting. ARCTICPURE EPA supplies 45% (450 mg) of EPA—one of the highest concentrations available. ARCTICPURE EFA™ ARCTICPURE EFA is a source of EPA, DHA, and also GLA (gamma-linolenic acid) from borage oil, and additional omega-3 fatty acids including ALA. GLA is an essential polyunsaturated fatty acid. It is used by most cells to produce the soothing, intracellular, hormonelike messengers known as series 1 prostaglandins (PGE1), which help maintain the balance of many functions in the body. GLA supports the immune system and helps maintain healthy skin and circulation. This essential nutrient is incorporated into our cell membranes, where it helps to maintain fluidity and permeability. Stabilized for Freshness ARCTICPURE oils are enhanced with antioxidants such as lecithin, ascorbyl palmitate, vitamin E and rosemary oil, for extended shelf life.

Macular degeneration is a medical condition that affects older adults in most cases which results in a loss of sight or vision just in the center of the visual field due to damage of the retina. This is a very serious condition of the eye and it progresses over the years and in case left untreated may lead to further loss of sight. It has been found to be a major cause of older adults being visually impaired and usually age range is 50 years or older. Macular degeneration makes it hard or impossible to read or recognize faces, even though enough peripheral vision remains to make daily life activities remain doable.

In the past decade, ginkgo has received much attention. It has been revered throughout China and other areas of Asia for thousands of years. However, its popularity increased in Western countries. An increase in sales can be attributed to interest in the benefits of ginkgo on conditions that are associated with aging like Alzheimer’s, memory loss, dementia, and circulatory disorders. Often, gingko is used to increase the blood flow to the brain, which improves memory problems like Alzheimer’s, to prevent strokes, and to increase blood circulation through vasodialation. The improved circulation is also thought to improve ear conditions, help blood flow to the retina, aid in preventing muscular degeneration, reduce frequency of asthma attacks, and help transplant recipients avoid rejection. 
Ginkgo has also been found to be effective in treating migraine headaches. In one study that took place in 1975, ginkgo extract was given to individuals who were suffering from migraines. Results concluded that eighty percent of the patients showed improvement or were cured of the condition. 
This is extremely helpful in conditions like retinopathy, cataracts and macular degeneration. The central nervous system possesses fat lipids in the cell membranes that are typically attracted by free radicals. Ginkgo can help protect these cell membranes and prevent condition which can occur in the brain and nervous system that are often associated with aging, like memory loss.
