What is Resveratrol?
Resveratrol is naturally occurring phytoalexin produced by some higher plants in response to injury or fungal in fection. Phytoalexins are chemical substances produced by plants as a defense against in faction by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.
Resveratrol is extracted from Polygonium cuspidatum and grape skin, its rich with Both cis - resveratrol and trans-resveratrol.

Main function:
Resveratrol helps lower cholesterol, and is as much as 10 to 20 times more potent than vitamin Ein protecting against LDL oxidation, a process that has been linked to the development of cardiovascular disease. It is also thought to discourage tumor growth by blocking the action of Cox-2, an enzyme that researchers believe contributes to the development of colon cancer. Additional studies suggest that resveratrol may be useful in both preventing and treating cancer.
Resveratrol is found in the stems, leaves, and skins of grapes. Although a glass or two of red wine each day may lower the risk of heart disease, one recent study shows that alcohol-free red wine works just as well. Resveratrol is also present in purple grape juice, red or purple grapes, and peanuts. However, because of the fermenting process, resveratrol levels are higher in red wine than other natural sources which has about three times as much resveratrol as grape juice.
Resveratrol supplements are also now available, and are usually combined with grape extracts or other antioxidants. Since researchers are just beginning to explore the benefits of resveratrol, there is no Recommended Dietary Allowance (RDA) for this substance; to date, no side effects, toxic symptoms, or drug interactions have been reported in connection with resveratrol consumption.
Dosage:
Researchers believe that 500 milligrams daily is the minimum amount of resveratrol needed to protect against cancer. A glass of red wine contains approximately 640 micrograms of resveratrol, and a handful of peanuts supplies nearly 75 micrograms.
