Many people consume lutein, either as a supplement in in vegetables containing lutein, because it can provide protection from diseases of the eye. A recent study has shown that lutein can protect the heart as well. Researchers found some correlation between higher levels of lutein in the bloodstream and a lower risk of heart disease, stroke, and metabolic syndrome. Metabolic syndrome is a medical term for a group of conditions including abdominal obesity, high blood pressure, and high triglycerides. Lutein, a carotenoid, is found in dark, leafy green vegetables. Key Takeaways:
"Dr. Elizabeth Leermakers decided to look into “lutein’s positive effects against inflammation and oxidative stresses in the eyes,” and together with a team of researchers, she searched for links between the presence of lutein (or a lack of the carotenoid) and diseases caused by stressors like heart attack, metabolic syndrome, and stroke."

Why Involving Lutein In Your Diet Is Important The sense ofsight is very important because it allows us to see things and appreciate its beauty and we have our eyes to thank for that. Our eyes are being used every waking second of our lives so that we can see the world around us and be able to do things that we want to do. But the sad thing is that our eyes just like any other organ in our bodies get damaged if we do not take care of it properly. There are a lot of people who have regret their terrible sense of sight because of not taking care of it properly while others regret totally losing their sight. There are plenty of ways to take care of your eyesight and one of the most important things to do is to eat food that has the nutrient Lutein. Where is Lutein found? Lutein is a carotenoid that is normally found in fruits, vegetables or anything that comes from plants. 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.

1. Granulocytes such as eosinophils, basophils and neutrophils – half day to 3 days 2. Stomach and colon lining cells – 2 to 4 days 3. Sperm cells – 2 to 3 days 4. Epithelial cells of the small intestines – 5 to 7 days 5. Platelets – 10 days 6. Skin epidermal cells – 14 to 28 days 7. Lymphocytes, macrophages and endothelial cells – 2 months to a year, but may vary 8. Pancreatic cells – a year or more 9. Bone cells – 25 to 30 years As shown above, these human cells have an expected time of death. However, if the body is exposed to harmful toxins, their life span significantly decreases. As we know for a fact, the body undergoes many biological reactions almost every second. The reaction is called oxidation process which is essential to the body. However, such reaction has harmful by – products in the form of free radicals. Free radicals can cause the body significant damage. Free radicals can cause destruction and death of the healthy cells of the body and also affect the body’s cellular division. This kind of chemicals can potentially tamper DNA replication during cell division. Once cellular division is tampered, abnormal growths would likely happen. Aside from the naturally occurring free radicals, external stressors can also cause damage to the cells of the body. Some of these include pollutants, harmful chemicals and irritants. These harmful chemicals can potentially lead to the development of certain disease conditions such as heart diseases, stroke and cancer. Fortunately, there are many antioxidants which can greatly help in the prevention of free radical damage by protecting the cells of the body. Antioxidants are molecules which can effectively prevent the oxidation of other molecules. There are many natural antioxidants found among plants and animals. Some common antioxidants are glutathione, vitamin C and vitamin E. Other nutrients which have antioxidative property include beta – carotene, Lutein, lycopene, vitamin A and selenium. Fruits and vegetables are great sources of antioxidants. Nuts, grains, meat, poultry products and fish are also good sources of such cell – protecting chemicals. In addition, dietary supplements of antioxidants are also widely available in the market. However, health experts highly suggest that before supplementation of antioxidants, medical evaluation must be done first to be completely safe.

An Anti-Oxidant? A term that describes a large range of more about 600 pigments which give plants their red, orange or yellow colouring is carotenoid. Some of the most commonly known in a regular Western region diets are alpha-carotene, beta-carotene, Lutein, zeaxanthin, and lycopene. Attention has been paid most to alpha-carotene and beta-carotene since these are the ones that can be synthesized by our body to form vitamin A, one of the body’s very powerful antioxidants. Lycopene, in particular, is has even been credited with some of the many anti-oxidant functions previously credited to beta-carotene. Prostate Health Prostate cancer is most common among men over the age of 50. The cause of this type of cancer, like almost all other cancers, is unknown, but some studies indicate alteration in testosterone metabolism possibly plays a role in its development. Prostate cancer generally grows slowly and can be undetected until late in the stage of the decease since it does not show any symptoms in the early stages. Symptoms can include painful urination, a feeling of incomplete emptying of the bladder, or blood showing with the urine. According to some studies prostate cancer patients that supplement with lycopene in addition to surgical procedures to remove the testicles may experience, less bone pain, and live longer than those who does not supplement. It has also shown that groups of patient that were tested with lycopene supplementation has a higher survival rate after a time frame of two years and no adverse side effects were observed in these men as well. This is achieved through lycopenes proven role in keeping the pathways open between cells which is vital in allowing the immune system to hold off cancer cells in its early stages. Although more research is still required to iron out what exact amount of lycopene will be most effective, the current results are already encouraging. However eating a moderately sized tomato a day can approximately provide 4 mg of lycopene and other tomato products, like an 8-ounce tomato juice or tomato paste provides up to 15 mg of lycopene just to give all the men out there an estimate. These are small portions of the diet that could easily be added without any major adverse effect to weight or health and seems too small to ignore given the possible benefits and minimal negative effects if any. Additional Lycopene Benefits It also has been found that lycopene can possibly as important as beta-carotene in protecting against the process of oxidation of Low Density Lipids (LDLs), also known as the “bad cholesterol”, which is now held to be the main cause of atherosclerosis, or hardening of the arteries which leads to cardio-vascular diseases like stroke or heart attack.

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.

Date:
December 18, 2007 11:43 AM
Eggs have many health benefits, among them being the fact they can be an excellent source of omega-3 oils that can promote better health in those that take it as a supplement. Hens fed on flax seeds are particularly high in omega-3 fatty acids, although eggs have many health benefits other than omega-3. Most of the health benefits of Omega fatty acids are well known, although many more are being continually discovered as scientists research the uses to which the substances can be put in our bodies. Omega-3 fatty acids have long carbon chains that are polyunsaturated, i.e. contain multiple double bonds in the hydrocarbon chain. As opposed to saturated fatty acids with no double bonds. They are important components of our neurological systems and help to build up cell membranes, but are probably best known for their effect in protecting us from cardiovascular diseases. Omega-3 fatty acids can help us to maintain a healthy heart, and so enable us to live longer. The current western diet has been changing to reduce cholesterol intake and improve our lifestyle. However, this has not all been well advised, and the resultant diet is rich in vegetable oils as opposite to animal fats, the relative levels of omega fatty acids having changed in favor of omega-6 fatty acids. These omega-6 fats are not as healthy for us as omega-3, and can lead to a thrombogenic state that more easily leads to cardiovascular diseases and blood clots. Rather than a normal omega-6 to omega-3 ratio of around 2:1, this ‘improved’ diet has increased it to anything up to 50:1. The American Heart Association has been advocating a diet richer in omega-3 fatty acids since 1996, yet while research continues to favor omega-3, the increase in consumption of vegetable oils has continued to increase, and with it a reduction in the overall health of a nation. Omega-3 enriched eggs have been introduced as one means of redressing the balance. Hens fed on flax seeds lay eggs with a much higher proportion of omega-3 fatty acids than normal: up to and over 150mg per egg. Such eggs also have reduced cholesterol – over 15% less, and also are higher in vitamin E, a strong antioxidant, by up to 300%. Two of the components of omega-3 oils, linoleic acid and linolenic acid, are what are known as ‘essential’ fatty acids. The term means that they cannot be manufactured in your body, so must essentially be introduced through your diet. When the human body developed to what it is now, the consumption of fish and other oils rich in omega-3 fatty acids was a significant part of our diets, and allowed our bodies to develop the biochemistry and metabolism that it uses today. If we now upset that biochemistry by cutting our intake of unsaturated fatty acids, our metabolism will suffer and our general health decline. This is one reason why humans should interfere with their natural eating habits as little as possible, or if we do so excessively we should use supplements to replace what we are excluding from diets that have been natural to us for countless millennia. It is dangerous now for the human race to suddenly switch to a significantly different diet without suitable supplementation, because we do not know the long terms effects of doing so. One way to maintain a steady intake of the fatty acids our metabolism needs in order to ensure our survival is to eat eggs, and especially omega-3 enriched eggs. Of course, eggs have a lot more beneficial health effects than just omega-3. Take choline for example. This is a trimethylated compound that is important in the metabolism of fats. It is the newest official B vitamin, and is an essential component of cell membranes. It is particularly important for the maintenance of the health of your brain, and preventing many brain disorders. It is also important in methylation, an important biochemical process, and also in the biochemical synthesis of the neurotransmitter acetylcholine. This substance is used to pass messages between nerve cells and from nerve cells to muscles, and a deficiency can cause many health problems, including heart disease and diseases of the vascular system. Methylation is a very important biochemical reaction, being used particularly in messages between body cells and is used to switch genes on and off. Up to 90% of Americans are deficient in choline, and subject to many diseases because of it. Symptoms include insomnia, fatigue, excess fat concentrations in the blood and problems with your nerves and muscular control. It can cause liver problems and heart problems, and cause a number of brain disorders. Choline is available in the diet from lecithin and egg yolks, and also soya beans, flax seeds, peanuts and potatoes. The typical American diet is not conducive to an adequate choline intake, and increased egg consumption can help to redress this. This is particularly true of eggs from hens fed with flax seeds, or linseed, from which the triple benefits of choline, omega-3 fatty acids and vitamin E are obtained. Just two eggs will provide you with almost 50% of your daily requirement of choline. Some are wary about the cholesterol content of eggs, but studies have indicated that it not so much the amount of dietary cholesterol that is eaten, but saturated fats that cause the excess deposition of cholesterol in the arteries. Cholesterol is an essential part of human biochemistry, and without any we could not survive. In fact, studies have shown that eating two eggs daily can improve your cholesterol levels Eggs are also rich in Lutein, and contain more than vegetables such as spinach. Lutein is an important carotenoid that is believed to prevent age related macular degeneration, which can lead to blindness, and also prevents the development of cataracts. Eggs also appear to have anti-clotting properties on the blood, and so help to reduce the thrombogenesis of omega-6 fatty acids. Without a doubt, eating eggs is very good for your health, and especially so if they are rich is omega-3 fatty acids. They contain a wide variety of nutrients and truly are a complete food packaged by nature. Some may prefer to stay away from eggs and miss the omega-3 benefits so there is an alternative for diets that exclude eggs. Omega-3 is available in a supplement form that one can take on a daily basis to reap the benefits omega-3 presents.

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.

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.

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.

Goji berry possesses a unique combination of flavonoids, vitamins, minerals and polysaccharides that are thought to be responsible for the antioxidant and anti-aging properties attributed to Goji. Studies have been conducted which characterize some of these antioxidant nutrients and show possible beneficial effects of the berry and its extracts on various systems and organs. In a study published in 2004, scientists undertook an experiment to assess whether Goji berries contained compounds that would be known to exert potential beneficial effects on skin complexion and anti-aging properties. After analyzing the berry, leaf and roots of the Goji plant, they found that the Goji berry contained a unique analog of vitamin C known as 2-O-(beta-D-glucopyranosyl) ascorbic acid. They determined that this compound was unique to the berry and not found in the other parts of the plant. Furthermore, the vitamin C compound was present in levels equivalent to those found in citrus fruits such as lemons. However, the question remained as to whether this vitamin C analog served as a precursor to vitamin C when ingested in the body. A further experiment in rats was performed to determine the intestinal absorption and tissue uptake of this vitamin C analog. The results showed that some of the compound was indeed metabolized into vitamin C in the blood, while the rest was absorbed intact. These studies suggested that the compound was easily transported from the blood into cells and tissues, where it is activated to active vitamin C. Therefore, the vitamin C from Goji berries seems to be highly absorbable and targeted for delivery to the cells that utilize it.1 Zeaxanthin is a carotenoid that is widely distributed in fruits and vegetables and, along with Lutein, is present in significant amounts in the macula of the human eye. Studies suggest that the presence of zeaxanthin is highly desirable for healthy visual function. Goji berries are used in traditional Chinese herbalism to support eye health and are also known to contain a high level of zeaxanthin dipalmitate. Researchers compared the bioavailability of this naturally esterified zeaxanthin to that of an unesterified form in 12 individuals who underwent a 23-day study in which they received one form or the other, and then switched. Administration was done on day one followed by a three-week washout period. The individuals were then crossed over to get the other form on day 23 in a single administration. Analysis revealed that the esterified zeaxanthin from Goji berry caused a higher increase in plasma levels than the non-esterified form, indicating higher bioavailability.2 A second study confirmed these findings. In this study, fourteen individuals consumed 15 grams of whole Goji berries daily for 28 days. These individuals were compared to thirteen age and sex-matched controls who did not consume the berries. Fasting blood samples were taken for all individuals before and after the 28-day period. Results indicated that zeaxanthin plasma levels increased 2.5-fold in the group who consumed the berries daily, suggesting the high bioavailability of zeaxanthin from the berries.3 Goji berry was also studied on various measures of antioxidant activity. Researchers subjected three Chinese herbs, one of which was Goji berry, to various assays of reactive oxygen scavenging potential. The results indicated that all of the herbs had significant free radical scavenging properties; however, Goji berries showed the most potent scavenging effect in the assays. Goji berry was especially strong at inhibiting the formation of superoxide anion and scavenging free radicals. The researchers concluded that among these herbs, Goji could be considered the best antioxidant to promote healthy aging.4 An interesting study was performed in human skin cultures to determine the mechanism of the potentially protective effect of Goji berry extracts. Researchers found that bathing human skin cultures with an extract from Goji berry impacted the function of several enzymes that promote skin aging. This provides evidence of an anti-aging and antioxidant effect of Goji berry extract in these human skin cultures. Researchers also noted that when these skin cultures were subjected to suboptimal growth conditions (lack of adequate nutrients), supplementing the medium with this Goji berry extract allowed the skin to maintain normal metabolic functions.5 Goji berry extract contains numerous compounds that confer potent antioxidant protection to various tissues.*

"PHYTONUTRIENT ANTIOXIDANT" Astaxanthin
Carotenoids are a class of lipid-soluble natural pigments found in plants, as well as in phytoplankton and certain fungi and bacteria. The red, orange and yellow colors seen in fruits and vegetables are from carotenoids. When various aquatic animals such as salmon and shrimp eat plants containing some of the over 700 compounds that make up the carotenoid class, those animals are also decorated with the same brilliant colors. However, carotenoids do more than provide color - they’re powerful phytonutrient antioxidants. Beta carotene, Lutein, and lycopene are some of the more well-known carotenoids, but the most powerful found to date is astaxanthin. Astaxanthin is a fat-soluble carotenoid with a unique molecular structure that makes it an extremely effective antioxidant. The PDR® Medical Dictionary 2nd Edition defines an antioxidant as, “An agent that inhibits oxidation; any of numerous chemical substances, including certain natural body products and nutrients, that can neutralize the oxidant effect of free radicals and other substances.” Not only is astaxanthin a potent free radical scavenger, but it also can protect against oxidation, which limits the number of free radicals produced. Additionally, it’s very effective at quenching a molecule called singlet oxygen, a harmful reactive oxygen species formed through normal biological processes. Singlet oxygen possesses a high amount of excess energy that must be released to keep it from damaging other cells. Astaxanthin absorbs this energy and dissipates it as heat, and in the process returns the singlet oxygen to a grounded state. A growing body of research is showing that astaxanthin is the creme de la creme of phytonutrient antioxidants. Studies comparing astaxanthin to other carotenoids have shown it to possess antioxidant activity up to 10 times stronger than that of beta carotene, canthaxanthin, Lutein and zeaxanthin.4 A study published in 1990 conducted by Kurashige and associates compared the effectiveness of vitamin E and astaxanthin for the prevention of lipid peroxidation. The results showed that astaxanthin is 100-500 times more effective in preventing lipid peroxidation in vivo than vitamin E.5 Astaxanthin in algae provides protection against the effects of ultraviolet (UV) light exposure, and studies are showing that this protective effect is also imparted with dietary astaxanthin. Scientists believe that astaxanthin effectively scavenges the oxygen radicals produced through photo-oxidation caused by UV exposure. A 1995 study by Savoure and associates studied the protective effects of astaxanthin, beta carotene and retinol against UVinduced photo-oxidative stress. The results showed that astaxanthin is extremely effective in preventing increases of certain polyamines created through photo-oxidation, which damages skin. A particular polyamine was found to increase only 1.5-fold in subjects fed astaxanthin, whereas subjects in the control group experienced a significant 4.1- fold increase. It was concluded that astaxanthin works through a particular enzyme, increasing this enzyme’s consumption of polyamines in response to irradiation. Research has shown that astaxanthin also offers cardioprotective effects through its ability to decrease oxidation of HDL (“good” cholesterol), which is a cholesterol transporter in the blood. It‘s well established that high levels of HDL and low levels of LDL (“bad” cholesterol) are desirable for healthy cardiovascular function, so protecting HDL from oxidation means there’s more circulating in the bloodstream. In a 1992 study by Murillo, subjects were fed dietary astaxanthin for 30 days. HDL cholesterol increased 57mg/dL, compared to the control diet (42.4 mg/dL). LDL cholesterol decreased from 12.5 mg/dL to 9.6 mg/dL. Clearly, astaxanthin exhibited an influence on the ratio of these two lipoproteins. We can thank the lobster for the discovery of astaxanthin. Researchers working with an extract of the lobster Homarus astacus first characterized astaxanthin in 1938. It was soon discovered that astaxanthin is abundant in nature, although mostly in very low concentrations. The greatest source found is in green algae called Haematococcus pluvialis, which also contains other carotenoids such as beta carotene and Lutein. NOW® Foods Astaxanthin supplies 4mg of this effective phytonutrient antioxidant and is an excellent source of this outstanding member of the carotenoid family. The astaxanthin used for our product is BioAstin® supplied by the Cyanotech Corporation, one of the premier suppliers of highquality astaxanthin taken from Haematococcus pluvialis, the richest natural source discovered. In addition to Astaxanthin, NOW® offers other carotenoids, including Lutein, Beta Carotene and Lycopene. Research continues to support the inclusion of carotenoids in the diet to support overall health. This is even truer for those with less than perfect diets and for those who smoke or spend any time with someone who does.

Your Cells Supercharge Your CellsThe differences between aging and growing old are poles apart. Sure, they may sound similar in nature. But when you think about it, the two are as different as night and day. Growing old is about retirement and travel and enjoying what you’ve worked an entire life for. Aging, on the other hand, summons images of wrinkled skin, brittle joints, cloudy minds and medicine cabinets full of prescriptions. It’s safe to assume that the majority of us want to look, live, and feel better as we grow old. Not the opposite. Many of us are on the right track - committed to a healthy lifestyle that includes regular exercise and a well-balanced diet. And yes, these do serve as a solid foundation for good health during our golden years. It is our cells, however, that ultimately determine who grows old, and who just ages. Still, slowing the proverbial hands of time is not all about health clubs and organic produce. If you want to grow old gracefully, you must nurture the ten trillion cells that defi ne you physically. Why? Because these cells are constantly under attack by free radicals - unstable molecules that either lack, or have an unpaired number of electrons. They scour the body in search of stable cells, and do whatever they can to rob them of their electrons, a process more formally known as oxidation. Considering that it’s environmentally impossible to completely avoid contact with the billions of airborne toxins that cause free radicals, the only other option is to safeguard your healthy cells. Making the commitment to a healthy lifestyle is the fi rst step in the process, and can be accomplished by eating healthier foods, exercising on a regular basis, and paying close attention to what you are exposed to environmentally. The next step is to nourish and protect your cells. The best way to do this is to consume foods that are rich in antioxidants and other cell-friendly nutrients. Unfortunately, this task is often much easier said than done. Today’s average adult is busier than ever, making it far more diffi cult to consume fresh, unprocessed meals 100% of the time. This does not, however, imply that all hope is lost. Over the years, the nutritional sciences have made stunning advances that afford you the opportunity to live your life while still safeguarding the integrity of your most basic building blocks. Here are a few of the best. Antioxidants Antioxidants work at the cellular level to paralyze the free radicals that cause oxidation throughout the body. Some of today’s most popular nutrients and dietary supplements fall into this category. They include vitamins A, E, and C, Selenium, Zinc, Alpha Lipoic Acid, Lycopene, Lutein, CoQ10, in addition to a host of others. And though similar in function, each of these free radical fi ghters has a unique role within the body. Take CoQ10 for example. It’s present in every cell of the body, and is especially important for cardiovascular support. Lutein has been used extensively to prevent oxidation in the macular regions of the eyes. Zinc is a powerful immune system booster that has become extremely popular during cold and fl u season. Alpha Lipoic Acid is both fat and water soluble, and is commonly referred to as the “universal” antioxidant based on its ability to quench free radicals anywhere in the body. Immune Boosting Herbs Herbs such as Astragalus, Olive Leaf, Rhodiola, Echinacea, Panax Ginseng and Ashwaganda have been used for centuries to help support healthy cells and strong, responsive immune systems. They’ve also been shown to exhibit natural synergistic effects when used together. Today, they remain one of the most popular ways to naturally promote all-around wellbeing. When it comes to supporting healthy cells, NOW is pleased to offer one of the best selections of antioxidants, herbs and immune support formulas. Be sure to look for these and other great products at fi ne health food retailers, nationwide.* OPCs OPCs (proanthocyanidins) are high-powered polyphenol antioxidants that belong to the fl avonoid family. Grape seed extract, pine bark extracts such as pycnogenol and enzogenol, bilberry, gingko biloba, resveratrol and others all fall into this category. Research continues to suggest that OPCs work in the same manner that traditional antioxidants do, however their ability to eradicate free radicals is much greater and more versatile. Equally appealing, OPCs can easily cross the blood barrier of the brain to help protect brain and neural tissues from the damage caused by oxidative stress. Mushroom Extracts Throughout history, many civilizations have relied on organic mushroom extracts to encourage wellness. What we know now is that mushrooms such as Shiitake, Maitake, Reishi and others are rich in 1,3 Beta-glucans - soluble fi ber compounds that help support both innate and adaptive immunity. In addition, the active compounds in some mushrooms have been shown to stimulate the production of microphages, T cells, and other natural killer cells. These biological warriors serve at the front line when it comes to responding to bacterial attacks. They are of immeasurable value to the immune system, though drastically lacking in today’s average diet. In just the past few years, more and more healthconscious individuals have learned fi rst-hand how benefi cial they can be in the preservation of healthy cells.

Vitaberry Plus +™ Super Fruit AntioxidantBy Nilesh Patel, NOW Quality Assurance, April 20, 2005 Why are FRUITS AND VEGETABLES important? “Diets rich in FRUITS AND VEGETABLES may reduce the risk of some types of cancer and other chronic diseases.”- National Cancer Institute. OXYGEN AND ANTIOXIDANTS As we all know, “Oxygen is critical to life,” but is itself a double-edged sword. While oxygen is necessary to sustain life and for natural defense against microbes, too much oxygen in our cells can lead to the production of “free radicals” (mitochondrial respiratory chain) or ROS (Reactive Oxygen Species). Free radicals come in many forms - singlet oxygen, hydrogen peroxide, superoxideperoxynitrite, to name a few - but all have one commonality. Each has an unpaired (unbalanced) electron, a situation it remedies by stealing an electron from a stable molecule. This sets off a domino effect of oxidation, a chain reaction that usually ends up damaging cellular integrity and compromising overall health. Nature has a defense system in place to protect these processes in the form of antioxidants. Whether endogenous (produced by the body, such as liver enzymes, SOD, coenzymes and sulfur-containing compounds) or exogenous (obtained through the diet, such as vitamins C & E, bioflavonoids, carotenes, etc.), antioxidants “quench” free radicals by donating an electron to stabilize a molecule, thus controling the chain reaction and stopping the oxidation “domino effect”. ANTIOXIDANT-RICH FOODS Research suggests that eating plenty of foods high in antioxidants helps to slow the processes associated with aging and protect against many chronic diseases. Maximizing one’s antioxidant power will enhance overall health. Fruit and vegetables contain both nutritive and non-nutritive factors that can affect oxidative damage and enzymatic defense and might contribute to redox (antioxidant and prooxidant) actions. A new “6-a-day” study looked into the effects of fruits and vegetables on markers of oxidative stress and antioxidative defense in healthy nonsmokers by The Danish Institute for Food and Veterinary Research in Denmark. The study found that fruits and vegetables increase erythrocyte glutathione peroxidase activity and resistance of plasma lipoproteins to oxidation more efficiently than do the nutritive factors (vitamins and minerals) that the fruits and vegetables are also known to contain. Certain berries, such as blackberries, also contain salicylates, which are also linked to heart health and prevention of atherosclerosis. The protective effects of fruits and vegetables intake on both heart disease death and deaths in general have previously been demonstrated but researchers at the Human Nutrition Research Center on Aging at Tufts University, Boston. Quercetin is an anti-oxidizing flavonoid found in many berries (such as cranberries, bilberries, blueberries, strawberries, etc.) and can prevent CVDs (coronary vascular diseases), according to a recent Finnish study. All these natural plant polyphenols are responsible for the colors of many red and purple berries, fruits, vegetables and flowers. GOVERNMENT GUIDELINES The new federal guidelines released earlier this year by the U.S. Department of Health and Human Services (HHS) and U.S. Department of Agriculture (USDA) recommend eating more fruits and vegetables, combined, than any other food group -- five cups or about 10 servings a day for most adults. The amount of fruits and vegetables recommended has increased for men and women of every age. “Fruits and vegetables are the "good news" story of the new Dietary Guidelines for Americans for food-loving consumers, the industry and America's public health”, stated the Produce for Better Health Foundation (PBH). Eating a variety of colorful phytochemical-rich fruits and vegetables has been associated with lower risk of some chronic diseases such as cancer and heart disease. Many authoritative organizations such as the National Cancer Institute and The American Heart Association recommend getting phytochemicals from whole foods, such as fruits and vegetables, rather than from individual component supplements. The Scottish government is promoting healthy eating through a scheme designed to increase purchasing of fruit and nutritional foods. Scottish health minister Andy Kerr said, "This initiative shows that healthy eating can be good for customers and good for business." Scottish women are said to have the highest rates of death from lung cancer in the world as well as the highest rates in Europe for coronary heart disease. They also have low consumption of fruits and vegetables, shown in studies to help protect against some cancers and benefit heart health. ROS (Reactive Oxygen Species) Free radicals and oxygen free radicals play an important role in the development and progression of many brain disorders such as brain injury, neurodegenerative disease, and Down syndrome. Oxidative stress is an important factor in the etiology and pathogenesis of diabetes & is also linked to other host of degenerative health conditions. Fortunately, antioxidants are available to support the body’s defense and fight disease and aging. Examples of “Fast acting antioxidants” in the body (serum) are: uric acid (polyphenols), ascorbate, bilirubin, vitamin E (the later two are lipid soluble). Examples of “Slow acting antioxidants” are glucose, urea nitrogen etc. In short, free radicals, reactive oxygen species (ROS) and reactive nitrogen species (RNS) are generated as by-products of normal cellular metabolism. Their deleterious effects are minimized in vivo (in the body) by the presence of antioxidant systems. How do Antioxidants work? Antioxidants are substances in plants that help maintain health. Antioxidants protect against damage to cells caused by too many “free oxygen radicals,” which form because of the effects of oxidation. Smoking, sunlight, heavy exercise, and pollution all increase oxidation in the body. Most people would benefit by eating more (five to nine or more servings) fruits and vegetables & colorful plant foods, such as purple, dark green, yellow, orange, blue, and red ones, each day. These have healthful pigments along with antioxidant nutrients such as vitamin C, carotenoids, beta-carotene, lycopene, Lutein, zeaxanthin, vitamin E, selenium, flavonoids, and other beneficial substances. There are numerous ways in which these antioxidants affect, but can be explained in two groups: Alpha (a) Effects: This refers to the scavenging or neutralizing of free radicals. These effects do not change the way humans (or animals) feel. There are also no noticeable health, psychological or emotional benefits. While there are no obvious changes, increased total antioxidant intakes are associated with decreased tumor rates, prevention of heart attacks and increased longevity. Beta (ß) Effects: These are the changes on health, psychological or emotional state that you or others will notice. In this case, the antioxidant is affecting metabolic processes (enzymes) with consequent changes in the physical (improvement in joint movements, improved skin condition, tissue damage recovery), emotional (better ability to cope with stress) or psychological state (increased alertness). The ORAC value Because most of the active nutritional components in fruits and vegetables are antioxidants, accurate measurement of antioxidant activity serves as a good indicator of potential health benefit. Scientific opinion runs high that ORAC (Oxygen Radical Absorption Capacity) will eventually become a government standard of reference for overall daily fruits and vegetables intake. ORAC units are a measurement of the ability of food to stop oxidation. It is most generally expressed in terms of Trolox equivalent per gram (µmole Trolox equivalents (TE)/g). POPULATION DATA A survey done by the National Research Council indicates that only 10% of the US population consumes the recommended five servings of fruits and vegetables per day. The equivalent to eating 5 mixed servings of fruits and vegetables per day is about 1,670 ORAC units. Based on scientific evidence it is suggested that daily antioxidant intake should be increased to between 3,000 and 5,000 ORAC units per day, per human subject, in order to reach a significant antioxidant capacity in blood plasma and other tissues. WHAT IS NOW DOING TO HELP? In accord with our mission, “To provide value in products and services that empower people to lead healthier lives,” NOW® Foods is introducing an ALL-FRUIT-DERIVED antioxidant product called VitaBerry Plus +™ Super Fruit Antioxidant Vcaps (vegetarian capsules) (product number #3336). At time of manufacture this product provides an ORAC value of at least 2,500 units per serving from a full-spectrum antioxidant blend of fruits containing phytochemicals and phenolic compounds such as anthocyanins, proanthocyanins, chlorogenic acid, ellagic acid, quinic acid, resveratrol , many organic acids, resveratrol and vitamin C. VitaBerry Plus +™ is formulated with VitaBerry™ Hi-ORAC Fruit Blend [a proprietary blend of fruit extracts & concentrated powders containing Wild Blueberry (Vaccinium angustifolium) extract, Grape (Vitis vinifera) & Grape seed extract, Raspberry (Rubus idaeus) & Raspberry seed extract, Cranberry (Vaccinium macrocarpon), Prune (Prunus domestica), Tart Cherry (Prunus cerasus), Wild Bilberry (Vaccinium myrtillus) extract & Strawberry (Fragaria virginia)], Hi-Active™ Orange (Citrus sinensis) and Pomegranate (Punica granatum) min. 40% ellagic acid fruit extract. One gram of VitaBerry™ Hi-ORAC Fruit Blend provides at least 6,000 ORAC units (i.e., µmole Trolox equivalents (TE)/g). (Also watch for an upcoming antioxidant product from NOW called Enzogenol® (Pinus radiata bark extract from New Zealand) with Rutin (a flavonoid from South American fruit of Dimorphandra mollis) and Grapeseed extract. IS IT EFFECTIVE? Total ORAC value includes both lipophilic and hydrophilic components. VitaBerry Plus +™ contains only water/hydroethanol based extracts and concentrated (100:1 to 125:1) freeze-dried fresh fruit blends, so the lipophilic ORAC value is mere 2-4% of the total ORAC value. Glutathione peroxidase is a selenium-containing enzyme that decreases cell death from brain injuries. It also acts as a critical first-line antioxidant defense on the airway (respiratory) epithelial surface against ROS and RNS (reactive nitrogen species. Genetics research has found that the glutathione S-transferase gene controls the onset of Alzheimer’s, Parkinson’s disease etc. Taking glutathione (GSH) itself as a supplement does not boost cellular glutathione levels, since it breaks down in the digestive tract before it reaches the cells. So glutathione precursor dietary supplements (such as NAC and GliSODin), along with fruits and vegetables, are effective in boosting intracellular levels of GSH. The lungs have a defense system against the ROS oxidants consisting of low molecular weight antioxidants such as GSH and intracellular enzymes such as SOD, catalase and glutathione peroxidase to protect against the toxic effects of oxidants generated within the cells. Some of the primary effects of VitaBerry Plus +™ against the common reactive free-radical species or ROS are as follows: - Superoxide dismutase-SOD (destroys Superoxide radicals),- Catalase (neutralizes peroxides), - Functions similar to reduced Glutathione (GSH), - Glutathione peroxidase enzyme (detoxifies peroxides, using GSH as a reducing agent), - Functions similar to Glutathione S-transferase (GST), - Nullifies Superoxide-generating NADH/NADPH oxidase system In conclusion More concentrated than fresh berries, with over 6000 ORAC units per gram, VitaBerry Plus +™ provides consumers with the antioxidant power of almost 15 servings per day of FRUITS AND VEGETABLES ina convenient vegetarian capsule form! VitaBerry™ PLUS +™ (# 3336) provides a powerful, convenient way to supplement diets that do not include sufficient fruit and vegetable antioxidants Selected References: USDA/HHS guidelines report at: etaryguidelines/dga2005/document/

Benefits of Total Daily Formula All fruits and vegetables contain carotenes, the plant pigments responsible for the rich variety of colors we enjoy in the natural world. Beta carotene is the most familiar member of the carotene family. But beta carotene never exists by itself; it is always found with other carotenes in foods. We need more than just beta carotene alone. Carotenes are powerful antioxidants, which means they help reduce the body's free radical burden. Research suggests that carotenes work as a team to keep us healthy.5 Total Daily Formula provides beta carotene, alpha carotene, Lutein, lycopene, zeaxanthin and cryptoxanthin from natural sources such as algal extracts, carrot oil, marigold and tomatoes (Caromix®). Total Daily Formula uses only corn-free vitamin C (ascorbic acid). The full daily intake of 6 tablets provides an exceptionally generous 800 mg of vitamin C. Total Daily Formula supplies ample amounts of all essential B vitamins. Vitamin B3 is given as niacin plus an extra helping of niacinamide, the non-flush form of this important vitamin. The body uses pantothenic acid (vitamin B5) to deal with stress, so the formula provides 150 mg, which is 15 times the RDA. Vitamin B6 is another B vitamin people may run short of, so 60 mg -- 30 times the RDA -- is supplied. The formula contains 800 mcg of folic acid, the vitamin now recognized by the FDA as essential for prevention of neural tube defects in unborn babies. Folic acid also helps prevent accumulation in the body of homocysteine, a metabolite of the amino acid methionine.6 A high blood homocysteine level is now considered to be a risk factor for heart disease.7 Flavonoids, also known as "bioflavonoids." are plant pigments widely distributed throughout the plant kingdom.8 Previously known as "Vitamin P," because they help reduce capillary permeability (leakiness) flavonoids are now regarded as "semi-essential" non-vitamin nutrients that benefit health in a variety of ways.9 In addition to maintaining the structure of blood vessels, flavonoids function as versatile antioxidants. Flavonoids protect vitamin C from destruction by free-radicals, helping to preserve the body's vitamin C supply.10 Total Daily Formula provides 100 mg of pure flavonoids from 112 mg of citrus extract. Three superior sources of Calcium Total Daily Formula contains three of the best absorbed and most effective forms of calcium available. MCHC (microcrystalline hydroxyapatite concentrate) is a naturally-derived compound composed of calcium, plus all the minerals and organic factors in living bone tissue. MCHC has been clinically shown to benefit bone health.11 Calcium citrate malate is a very well-absorbed form of supplemental calcium shown in recent research to be helpful for postmenopausal women.12,13 Calcium glycinate is chelated with the amino acid glycine, one of the most efficient mineral carriers for effective absorption.14,15 Magnesium is essential for strong bones and healthy hearts. This versatile mineral also regulates nerve function, keeps muscles relaxed and coordinates activity of over 300 enzymes in the body.16 Total Daily Formula contains 100 percent magnesium glycinate for exceptional absorption and gentleness on the intestinal tract.17 Magnesium glycinate has been clinically tested on people with severe malabsorption with excellent results.18 Total Daily Formula provides - in addition to zinc, chromium, selenium and iodine - vanadium and molybdenum. Vanadium helps maintain normal blood sugar.19 Molybdenum works as a co-factor for enzymes that help detoxify and eliminate foreign substances from the body.20 Bioperine® for Enhanced Absorption Bioperine® is a natural extract derived from black pepper that enhances nutrient absorption. Preliminary trials on humans have shown significant increases in the absorption of nutrients consumed along with Bioperine®. 21 Betaine HCL - supplies HCL (hydrochloric acid) to assist digestion. All natural tablet coating made of vegetable concentrate and beta carotene.

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.

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.

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.

And now, based on the latest scientific research, we have improved the formula by adding even more antioxidants and other cutting-edge ingredients. According to Lyle MacWilliam, “Source Naturals made a top ranked multiple even better!” And based on Lyle’s analysis of the new formula, LIFE FORCE is now the highest rated multiple of any evaluated in the current edition of this guide, scoring a 100% rating. Bio-Align™ Yourself with Life Force LIFE FORCE MULTIPLE was chosen as one of America’s most elite and comprehensive multiples, as reported in the Comparative Guide to Dietary Supplements by Lyle MacWilliam, 3rd ed. LIFE FORCE received this acknowledgement by nutrition experts because it is uniquely effective. This Bio-Aligned Formula™ goes beyond ordinary multiples that simply replace nutrients missing from the diet. LIFE FORCE provides key organ-specific nutrients to support your body’s energy generation, heart, brain, immune system, musculoskeletal system, skin, liver, eyes, and more. When all your body systems function in harmony, everything in life comes together. Your mood is positive, your mind is clear, you’ve got energy in your step—that’s your LIFE FORCE working for you. Get Ahead with Activated Energy and a Healthy Metabolism Your metabolism determines how much you weigh, how energetic you feel, and the effective functioning of all your systems. LIFE FORCE is a rarity – a unique multiple containing an incredible number of nutrients at the potency levels that truly support your healthy metabolic function. For example, it contains coenzyme Q10, which plays a crucial role in cellular energy production. CoQ10 is a vital intermediate in the electron transport chain, one of the body’s energy production cycles, which converts glucose, or blood sugar, into ATP (Adenosine Triphosphate), a high energy molecule that is the body’s “energy currency.” LIFE FORCE also supplies alpha-lipoic acid and the potent R-lipoic acid form of lipoic acid, which are both referred to as the universal antioxidants and important intermediaries in the Krebs cycle, another energy production cycle. LIFE FORCE also contains tyrosine and iodine, both precursors to thyroid hormones. These hormones regulate key metabolic functions like heart rate, digestive function, weight management and energy levels. No discussion of metabolism would be complete without mentioning the B vitamins and their coenzymated forms, such as thiamin cocarboxylase, riboflavin mononucleotide, and the methylcobalamin form of vitamin B- 12. These critical vitamins and their immediately bioavailable coenzymated forms are formulated to play critical roles in thousands of enzyme reactions that promote carbohydrate metabolism, energy production, and the mental functions that invigorate and activate you as you move through your busy days. And now green tea extract with EGCG (Epigallocatechin Gallate) has been added to the formula for added metabolic support. Protect Your Heart and Circulatory System The amazing muscular organ that is your heart beats more than 100,000 times a day, 365 days a year, promoting vitality and alertness by constantly oxygenating our tissues. LIFE FORCE supports your cardiovascular system with antioxidant coenzyme Q10, which helps support heart muscle metabolism. LIFE FORCE also contains the minerals potassium and magnesium, electrolytes vital for healthy heartbeat and heart function, and the herb hawthorn, a rich source of antioxidant flavonoids, which has traditionally been used as a heart tonic. LIFE FORCE also supplies vitamins B-6, B-12 and folic acid to help maintain healthy homocysteine levels and vitamin K to support healthy circulation. Unlike common multiples, it supports cholesterol wellness, circulatory health and antioxidant cardiovascular protection, with both the typical d-alpha form of vitamin E but and the more potent and effective gamma-tocopherol and similarly structured tocotrienols. Skin and Musculoskeletal Support LIFE FORCE furnishes nutrients to build healthy bones, muscles and skin. We all know that calcium and magnesium are crucial for bone health, but many people don't know that there are a variety of nutritional cofactors that help build bone, such as vitamin D (which enhances calcium absorption and utilization), boron, manganese and copper. LIFE FORCE also supplies vitamin C and copper, necessary nutrients for collagen production (collagen is a key constituent of connective tissue in joints, skin and other areas), and the cutting-edge nutrient methylsulfonylmethane (MSM), an assimilable form of the mineral sulfur, used by the body to build and maintain connective tissues, including joint cartilage, hair, skin and nails. Additional nutraceuticals to support healthy skin include DMAE bitartrate, CoQ10, and alpha lipoic acid. LIFE FORCE also now includes rutin, quercetin, green tea extract and 65% more turmeric extract for your joint comfort. Brain and Nerves Nutrition The hectic pace and constant demands of life can keep our pulse racing, our nerves jangling and our temples throbbing. Our nervous systems are crying out, “Help!” LIFE FORCE provides that help. LIFE FORCE supplies the most highly bioavailable and bioactive forms of the amino acid tyrosine – the N-acetyl form and the acetyl-L form. Tyrosine is an important precursor to epinephrine and norepinephrine (collectively known as the catecholamines), which helps you respond to stress. It also contains high doses of vitamins C and B-6, required by the adrenal glands to produce the catecholamines. In addition, LIFE FORCE delivers the full spectrum of B vitamins, all important for healthy nervous system function. Now LIFE FORCE also contains a more bio-available form of tyrosine, acetyl-L-Tyrosine. And LIFE FORCE contains Neuroceutical® nutrients that support healthy brain function by furnishing DMAE and choline. Both are precursors to the important neurotransmitter acetylcholine and are important for memory focus and muscular movement. Choline is also a precursor to phosphatidylcholine, an important constituent of the cellular membranes that surround and protect our brain cells. In addition, LIFE FORCE contains the renowned herb Ginkgo biloba and now even more grape seed extract, both effective antioxidants that can prevent lipid peroxidation, which is critically important for the high amounts of fatty tissue in the brain. LIFE FORCE—good food for the brain. Immune Defense LIFE FORCE MULTIPLE supports your immune system, so you can feel your best through the seasons. LIFE FORCE contains the immunosupportive nutrient vitamin A, which fosters cell-mediated immunity and protects the epithelial linings of the respiratory and digestive tracts. Two forms of vitamin A are supplied: preformed vitamin A and its precursor, the potent antioxidant betacarotene. Other immuno-supportive nutrients in LIFE FORCE include vitamin B-6, vitamin C and zinc, which is fundamental for proper functioning of our T-cells, the “seek and destroy” cells of our immune system. LIFE FORCE also now includes 40% more lipoic acid, including the highly bioavailable alpha and R-isomer forms. Lipoic acid along with the B vitamins and CoQ10 promote building the energy reserves needed when the immune system needs to kick into high gear. Powerful Liver Support Your liver is responsible for converting many nutrients into their metabolically active forms before your body can use them. After activation, these nutrients travel through the blood stream to target organs where they perform their metabolic functions. Not only does the liver activate nutrients, but it also plays a crucial role in a variety of other metabolic functions, from fat digestion and cholesterol production to blood sugar regulation to the processing and elimination of toxins, an important role in today’s increasingly polluted world. For all these reasons, nourishing the liver is crucial. And LIFE FORCE does just that. LIFE FORCE contains alpha-lipoic acid, turmeric, silymarin and N-acetyl cysteine (NAC) – all potent antioxidants that support healthy liver function. NAC and alpha-lipoic acid both help produce glutathione, one of the liver’s primary detoxifying molecules. Silymarin, the active flavonoid complex of the herb milk thistle, as well as coenzyme Q10, have been shown in vitro to inhibit lipid peroxidation of cell membranes. Turmeric extract promotes bile flow and is a rich source of the antioxidant, curcumin. LIFE FORCE also contains choline and inositol, vitamin- like molecules which act as lipotropics, unique substances that prevent the deposition of fat in the liver. Since the liver is naturally high in fats, LIFE FORCE is one of the only multiples that contains the fat-soluble form of vitamin C, ascorbyl palmitate, for antioxidant protection. Complete Antioxidant Defense Oxidative stress is the primary cause of accelerated aging. This and other forms of free radical damage are constantly threatening your body. Whether it is from pollution, ultraviolet light, food additives, or from other sources, it is more critical than ever to protect your body with antioxidants. LIFE FORCE contains 24 of the most powerful antioxidants known to science, including eight new antioxidants based on the latest research. It contains antioxidants that are water soluble, such as quercetin and rutin, and ones that are fat soluble, such as alpha-lipoic acid and lycopene. There are antioxidants that are especially protective of specific body systems, such as Lutein to protect the macula in your eye, lycopene to protect your prostate gland, and tocotrienols to protect your arteries. Cutting-Edge Vision Nutrition The structure and functions of your eyes are very complex. LIFE FORCE contains nutrients to help support and maintain healthy eye tissue, which is particularly susceptible to oxidative stress from free radicals. To support your healthy macula, aqueous tissue and optical nerve signals, LIFE FORCE includes ingredients such as Lutein, astaxanthin, beta carotene, bilberry, zinc, lipoic acid and quercetin. Life Force Replenishes Essential Nutrients to Support Your Low Carb Lifestyle LIFE FORCE contains optimal levels of many nutrients that might be deficient in low carb meals. Counting carbs can lead to restrictions of nutrient-dense foods, such as dairy products, grains, fruits and vegetables. LIFE FORCE contains many of the same protective antioxidants, vitamins and minerals as fruits and vegetables, including betacarotene, vitamin C, vitamin E, flavinols, magnesium and selenium. It also contains high levels of the same vitamins found in grains, including all of the B vitamins, to support your body’s healthy energy metabolism. And it contains nutrients found in dairy products, such as calcium, potassium, vitamin A and vitamin D. Support Healthy Fat and Protein Consumption with Life Force Low carb lifestyles mean higher consumption of proteins and fats. Unfortunately, there are artery, heart, colon and many other health concerns associated with meals that are high in fat and protein and low in fiber and produce. However, the nutrients in LIFE FORCE can help you better process these foods when eating this way. LIFE FORCE contains high levels of protective fat-soluble antioxidants such as alpha lipoic acid, ascorbyl palmitate (vitamin C ester) and vitamin E to protect your body from the free radicals generated by consuming more fats. It also contains many nutrients for liver health, such as silymarin, CoQ10, NAcetyl Cysteine and turmeric to help support the fat metabolism your liver is responsible for. LIFE FORCE also contains a high level of the B vitamin biotin, which aids in fat, protein and energy metabolism. Complete Energizing Nutrition LIFE FORCE is the only multiple to target organ systems with specific nutrients and bio-botanicals, antioxidants and Neuroceuticals® for total body harmony and energy activation, system by system. Only this dedication to going deep to the cellular root of system imbalances can produce a multiple so effective that it is acknowledged in a prestigious scientific review, the Comparative Guide to Nutritional Supplements. A nutritional program with LIFE FORCE at its center can be an easy first step in joining the Wellness Revolution. The goal of this revolution is a long, healthy and fulfilling life. Allow yourself to feel your best, to achieve mental and physical harmony, to radiate energy and vitality. Feel your LIFE FORCE!

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

Date:
June 03, 2005 10:51 AM
It’s hard to imagine that the ancestor of the beefsteak tomato was a tiny yellow fruit first harvested by the Incas. Tomatoes have come a long way since their origin in the Andes, becoming more popular than any other fruit or vegetable in America. (Botanically, the tomato is really a fruit, despite the Supreme Court’s 1893 ruling that it’s a vegetable.) Today, our appreciation of this dietary staple is entering a new chapter. Modern nutrition science has delved into the biochemistry of the tomato and discovered unique phytonutrients with powerful influences on the human body. Utilizing this research, Source Naturals has introduced a concentrated form of the tomato’s most vital nutritional compound: Lycopene. Tomatoes and their Healthy Red Color Lycopene is the pigment that gives tomatoes, watermelons and some grapefruits their healthy red color. Found most abundantly in tomatoes (Lycopersicon esulentum), lycopene is a member of the carotenoid family. This group of phytonutrients are major contributors to the health of the human race. (Phyto is derived from the Greek word for plant.) Over 500 different carotenoids have been identified by science, and almost 10% of them are found in human blood and tissue. Best known is beta-carotene, whose important benefits have been well-documented. Other familiar phytonutrients include allicin from garlic, and capsaicin from chili peppers. Lycopene, Lutein, alpha-carotene and betacarotene are the most abundant of the carotenoids present in human blood and tissues. Human breast milk has been found to contain 19 carotenoids, including lycopene. Like many carotenoids, lycopene has evolved as an integral part of human biochemistry, with many benefits to our well-being. Since mammals cannot synthesize it, lycopene must be obtained from the diet. Lycopene and Prostate Function One of the most interesting aspects of the way phytonutrients 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 lycopene, it’s the most plentiful carotenoid in the prostate gland. Studies have explored the link between diets high in lycopene and proper prostate function. Lycopene Protects Cells Research has shown that lycopene may protect DNA by its powerful antioxidant activity against singlet oxygen free radicals, dangerous forerunners to cellular damage. Lycopene was found to be the most efficient biological carotenoid to neutralize singlet oxygen – almost 3 times more powerful than beta-carotene. Also, lycopene has a “sparing effect” for beta-carotene: lycopene sacrifices itself to free radicals so that beta-carotene can be reserved for conversion to vitamin A. Lycopene has another ability that has excited further investigation. It increases gap junctional intercellular communication, which is the chemical and electrical coupling between neighboring cells. This enables a healthy exchange of the signals that regulate normal growth – thereby offering a protective influence on cellular reproduction. Getting the Most From Tomatoes Until recently, lycopene was not commercially available, and hasn’t been studied as extensively as has beta-carotene. But now, thanks to a unique (non-chemical) proprietary process, lycopene can be obtained from specially bred and cultivated tomato varieties that are rich in lycopene, and very red. Source Naturals LYCOPENE is standardized to 5% lycopene in a base of vegetable oil. It also contains small amounts of other carotenoids, naturally present in tomatoes. While it’s important to continue eating fruits and vegetables, we can also benefit from the fruits of nutritional research. This is especially important since so much of our food supply has become denatured, lacking the traditional nutrition our bodies require. Source Naturals LYCOPENE is a significant step toward reclaiming the nutrients we need to help create a life of health and vitality. Get a taste of the 21st Century – Source Naturals LYCOPENE.

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.

The human body is composed of many different cells. These cells have varying functions as well as life span. The human cells, in general, are very complex. Some cells may last only within a day while others may be for life. Like for example, one blood component known as neutrophil lasts only within 24 hours. On the other hand, another blood component which is red blood cell has a life span of 120 days. One human cell which lasts for a lifetime is the stem cell. Stem cells are undifferentiated cells which are the source of blood cells. They supply the body throughout life both with red and white blood cells. Here is a brief outline of some cells of the human body with their corresponding life spans. 
Lycopene is a bright red carotenoid pigment and phytochemical found in tomatoes and other red fruits and veggies, like red carrots, watermelons and papayas however not strawberries. Although most chemical carotenes has vitamin A activity, lycopene does not. Lycopene is an essential intermediate in the biosynthesis of many carotenoids and in algae, plants, and other photosynthetic organisms.
