What is resveratrol:

Resveratrol is a phenolic compound that has been found to have strong antioxidant activity. Plants create resveratrol to protect themselves against the effects of poor growing conditions and severe weather. Resveratrol has been shown to reduce the oxidation of LDL cholesterol, total cholesterol and the risk of cardiovascular disease. There have been numerous studies that show the benefits of moderate red wine consumption on health. Red wine is fermented with the antioxidant-potent grape skins present; some studies suggest that the intake of red wine (and therefore resveratrol) may yield cholesterol-lowering effects.
