What is Bakuchiol? Bakuchiol is a plant-based compound that has been used medicinally for centuries. It is extracted from the seeds and leaves of the babchi plant, also known as Psoralea corylifolia. Bakuchiol has traditionally been used to treat a variety of skin conditions, such as eczema, psoriasis, and acne. More recently, it has gained popularity for its anti-aging properties. How Does Bakuchiol Work? Bakuchiol works by mimicking the effects of Retinol, a vitamin A derivative that is commonly used in anti-aging products. Retinol works by stimulating collagen production and cell turnover, which helps to reduce the appearance of fine lines and wrinkles. However, Retinol can also cause irritation, redness, and dryness, especially if you have sensitive skin. That's where bakuchiol comes in! Bakuchiol has been shown to provide many of the same benefits as Retinol without causing irritation. What are the Benefits of Bakuchiol? In addition to reducing the appearance of fine lines and wrinkles, bakuchiol has also been shown to improve skin elasticity and firmness. It can also help to even out skin tone and texture. If you're looking for an anti-aging product that won't irritate your skin, bakuchiol is a great option! The Now Foods Bakuchiol Skin Renewal Serum contains clinically-tested bakuchiol along with other naturally derived ingredients to help reduce the appearance of fine lines and wrinkles.

Retinol, which is a form of vitamin A, has become one of the most widely celebrated anti-aging products. This is because it works within cells to help slow breakdown of collagen and stimulate quicker growth of new collagen. This leads to smoother skin with less spots and wrinkles. One of the most important things to remember is that Retinol works best when applied at night. Sunlight can cause it to irritate the skin. The Woda skin care line currently has one of the most hailed products due to its addition of antioxidants to the formula. Key Takeaways:

Beta carotene: There are basically two kinds of vitamin A . Experts say that Retinol is a body fat soluble vitamin discovered mostly in liver, egg yolks, as well as the fats element of dairy products . Retinol vitamin A is furthermore referred to as pre-formed which is utilized instantly by the system rather than the provitamin vitamin A, also referred to as beta-carotene, that is transformed inside the body into Vitamin A . Experts also described this form as the water-soluble pro vitamin, beta-carotene, originating from plants. Beta carotene, in almost any serving, is not related to birth defects. Fruits for example carrots, tomatoes, kale and also spinach are pretty decent options for this vitamin. Advantages: Vitamin A palmitate is produced in synthetic kind for usage in cosmetics to deal with skin conditions as well as acne as well as wrinkles. Other employs for vitamin A palmitate incorporate treatment of eye issues for example Bitot’s spot, dry vision as well as retinitis pigmentosa. Disadvantages: Nutritional vitamin A signed up to palmitic acid. Vitamin A palmitate is the type accustomed to improve foods as well as pores and skin moisturizers.Vitamin A in their organic kind of Retinol is a common ingredient in topical ointments promoted as wrinkle reducers or even acne medications. In higher doses taken by mouth, it brings about dry, itchy or even peeling skin on the lip area and palms.

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

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

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

Supplement labels can be confusing!
The list of ingredients on some supplement labels can tax the mind of even a Ph.D. in nutrition! What’s worse, although labeling laws exist to counter misleading and non-uniform labeling, confusing and deceptive labeling, confusing and deceptive labeling practices continue to abound. Here’s some help to aid you in making better sense of supplement labels.
1.Begin at the Bottom
The supplement facts panel on the label of every nutitional supplement sold in the
2.Directions, Dose & Value
Directions: Though not required on labels, directions tell how and when to take supplements. This is important because timing your doses can affect absorption. In general:
· Vitamins are best absorbed when taken with food, and in divided doses throughout the day.
· Fat-soluble vitamins (A,D,E,K) require dietary fat for absorption, so are best taken with meals.
· Many minerals can be absorbed effectively at any time.
· Most herbs, probiotics, amino acids & proteolytic enzymes (not digestive enzymes, which should be taken with meals) are best taken on an empty stomach.
1. Serving size: SERVING SIZE is required on labels. It recommends the number of tablets, capsules, spoonfuls, ect. Taken at one time. Be ware that a serving is not necessarily the total recommended daily amount.
2. Cost-Effectiveness: To determine, first find the SERVING SIZE. Then read the directions to see how much servings are suggested daily. Finally, divide the number of servings needed into the number of SERVINGS PER CONTAINER.
Example: Assuming the two bottles above have the same ingredients and cost. The product on right offers more servings, and is a better buy. Product on left just has less nutritive ingredients, or more filler, in each pill.
3. % DV (Daily Value): The daily value of a nutrient represents the amount expected to meet the daily needs of an “average” healthy person. On labels, % DV indicates provided by one serving. DVs have not been established for herbs, essential fatty acids and other nutrients.
Note: Many experts in nutrition think that suggested DV levels for some nutrients are far too low to optimize health. This is why certain ingredients may be present at greater than 100% DV levels.
3.Games Labels Play
There is no free lunch in the world of supplements. A bottle that costs less probably contains less – either fewer nutrients, or less effective forms of nutrients. Educate yourself; compare ingredient amounts, forms and sources, and watch out for labeling tricks such as these.
“Padding” the label
“padding” the label is a common way for supplement marketers to make their ingredients list look more complete and beneficial than it really is. Padding methods include:
Example: CoQ10 useful range is 30mg to 400mg (milligrams.) product on left provides 1000mcg (microgram) of CoQ10, the equivalent of just one mg! product on right provides a beneficial 50mg.
Example: Whole grains such as oats are part of a heart healthy diet, but the product on left provides less than a pinch 20mg of oat bran. Product on right includes no irrelevant ingredients in useless amounts.
Example: Fiber and flavonoids are part of oats, not more ingredients.
The “Name’s the Same” Game
A common trick is to provide unproven, weak or useless forms of familiar, good ingredients. Buyer beware!
Example: Studies suggest that Pygeum bark standardized extract helps support prostate health. Product on left uses unresearched powdered bark.
Proprietary Blend = “It’s a Secret”
Some companies may hide the quantity and quality of their ingredients by calling their formula a “Proprietary Blend.” This term may allow manufacturers to use a lot of nutrient from a cheap source and very little from a good source without disclosing how much of each you are actually getting.
This deceptive practice is legal—as long as the secret blend:
· Is labeled “Proprietary Blend” (or fanciful trademark name)
· Lists individual nutrients in descending order by weight
· Lists the total weight per serving
When you see the word “Proprietary,” ask: “how relevant is the first or second ingredient?” Sometimes, the most abundant ingredients are either fillers, or inexpensive, less effective forms.
Example: Legally, product on left could contain 99% alfalfa filler and only 1% of all the other herbs together! The Good Label tells all.
Hiding Outside the Box
Another clever way to hide the quality of ingredients is by listing them outside the Supplement Facts box, in the Other Ingredients section located beneath the box. This section is usually intended for listing agents used in the tableting or encapsulation process.
Example: Agents used in supplement manufacture (i.e. cellulose and stearates) should be listed under Other Ingredients. Product on left also uses this section to list catchy sounding spirulina, lycopene, and grape seeds. With no amounts listed, assume these ingredients are present in low levels that provide little value. A supplement maker who is proud of a product’s nutritive ingredients will fully disclose amounts within the Supplement Facts box not list these ingredients along with manufacturing agents in the Other Ingredient section.
4.Understanding Herbs
Herb Forms: Powders, Tinctures, Extracts
The form, preparation and concentration of an herb affects its potency and influences the herb’s potential for therapeutic effectiveness. the potency of all herb forms except standardized extracts are uncertain and depends on factors invisible to the consumer (i.e. soil quality, rainfall, seasonal climate, harvesting methods, storage methods and age).
Know Your Plant Parts: Medicinal plants often have specific parts that are most effective therapeutically, such as the root for goldenseal, the leaf for raspberry, and the blossom for clover. Products using irrelevant plant parts may cost less, but offer little or no benefit!
Powdered Herb
Often encapsulated or used as tea, powdered herbs are more likely than other forms to lose potency when exposed to air. Fresh, high quality powdered herb may add therapeutic or nutritional value to a supplement. Low quality powders may provide little benefit. Look for expiration or “use by” dates.
Example: If the label doesn’t say otherwise, assume the form of herb is powdered. Better labels specify plant part and latin name (genus and species). Sometimes a less effective species of a plant is used to save money. Check to see if other related species may be equally effective.
Tinctures and Fluid Extracts
Tinctures contain the soluble parts of dried or fresh herbs, often extracted in a mixture of alcohol and water, vinegar or glycerin. Tinctures are usually dispensed by drops. This form is more stable and thus has longer shelf life than powdered herb.
Example: Better labels specify tincture strength as a ratio. Regular tinctures are made using 1 or 2 parts herb to 10 parts solvent, yielding strength ratio of 1:10 or 1:5. higher potency tinctures (also known as fluid extracts) use more herb in less solvent, yielding stronger 1:3, 1:2, or even high strength 1:1 ratios.
Concentrated and standardized extracts
Concentrated or standardized extracts (solid, powdered, liquid) are generally prepared from evaporated herbal tinctures or teas.
Example: A better label tells you the concentration strength by noting the ratio of herb to extract. This is often appears after the plant name.
Example: Standardized extracts provide a set percentage of an herb’s researched nutritive ingredient. Useless this percentage is noted on the label, the term “Standardized” is meaningless.
5.Beware of False Claims
Is it science of is it marketing? To avoid being misled, question all claims on supplement labels as well as in advertisements. Although government guidelines restrict the types of claims that manufacturers can legally use to promote their products, not all companies comply. Many promises mount to little more than marketing hype.
Use common sense to decide if a claim seems realistic. Be aware of emotionally charged, misleading language in advertising.
When doubt, contact the company and request information to support a claim. Unbiased research and human studies are most relevant. If the science seems legitimate, verify that the form and dose used in product match form and dose showing benefit in studies.

"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.

Helps maintain a healthy prostate gland. Supports normal urinary function. Comprehensive Prostate Formula-the Clinical Studies Saw palmetto extract is one of the world's leading herbal products for prostate support. Widely-cited clinical studies conducted over the last fifteen years suggest Saw palmetto extract can produce major improvements in prostate-related urinary function. In clinical studies, Saw palmetto extract has produced measurable improvements in urinary functions and prostate size. Quality of life scores have also improved. The results with Saw palmetto extract have been duplicated in open trials and controlled, double-blind studies.11,12,13 For example, in a large open trial, 505 men took 320 mg of Saw palmetto extract daily for three months.1 The results were evaluated with various measurements such as the International Prostate Symptom Score, the quality of life score, urinary flow rates, residual urinary volume, and prostate size. After 45 days these parameters improved significantly. After 90 days of treatment nearly ninety percent of both the doctors and patients regarded Saw palmetto extract as effective as therapy for the prostate. The changes in prostate health that accompany middle age are related to the hormone DHT, or dihydrotestosterone, a metabolite of testosterone. DHT levels rise, and DHT binds to prostate cells, accelerating growth of prostate tissue. Saw palmetto extract has been shown to inhibit 5 alpha-reductase, an enzyme that controls conversion of testosterone to DHT.14 Experimental evidence suggests Saw palmetto extract blocks the binding of DHT to prostate cells.15 The fatty acids and sterols in Saw palmetto are believed to be responsible for these actions.14,16 These include oleic acid, lauric acid, campasterol, stigmasterol, beta-sitosterol and others. Clinical studies have used extracts containing 85 to 90 percent fatty acids and sterols. Like Saw palmetto, Pygeum contains natural sterols and fatty acids.2 Although the mechanisms for its effect have not been clearly established, animal experiments suggest Pygeum may work by inhibiting prostate cell proliferation and reducing inflammation.17,18 In several European trials, Pygeum has successfully improved urinary function. In a large double-blind, placebo-controlled study, 263 men were given 100 mg of Pygeum extract a day for 60 days. Urination improved in 66 percent of the men taking Pygeum, compared with 31 percent on placebo, based on subjective and objective tests.19 Nettles are approved by the German Commission E as effective for relieving inflammation in the urinary tract.20 As far back as 1950, German investigators have observed favorable effects on the prostate with the use of Nettle root. These initial findings have been confirmed through case studies, as well as double-blind studies, published mainly in German medical journals. In a recent double blind study published in the journal Clinical Therapeutics, 134 men took a combination of Nettle root extract and Pygeum extract over a period of 56 days.3 Urination was significantly improved. L-Alanine, Glutamic Acid and Glycine As noted above, Drs. Feinblatt and Gant discovered that a combination of the amino acids L-alanine, glutamic acid and glycine has a positive effect on prostate-related urinary function.5 A controlled study of 45 men was conducted to follow up on these initial observations.21 The majority of subjects experienced complete or partial relief in urinary complaints such as nighttime urination and urgency.

There are basically two kinds of vitamin A . Experts say that Retinol is a body fat soluble vitamin discovered mostly in liver, egg yolks, as well as the fats element of dairy products . Retinol vitamin A is furthermore referred to as pre-formed which is utilized instantly by the system rather than the provitamin vitamin A, also referred to as beta-carotene, that is transformed inside the body into Vitamin A . Experts also described this form as the water-soluble pro vitamin, beta-carotene, originating from plants. Beta carotene, in almost any serving, is not related to birth defects. Fruits for example carrots, tomatoes, kale and also spinach are pretty decent options for this vitamin.
