1) Life Extension: Studies of bacteria, fish, and mice have showed that rezveratrol causes significant life extension. Bacteria such as yeast, and the fish, Nothobranchius furzeri, had lifespan increases of over 50%! Studies of mice found that while increased longevity was not shown conclusively; health and activity levels of older mice was significantly improved by taking the supplement. Older mice on fatty diets who experienced very little exercise but were given ResV ended up being just as healthy as young, slender mice who were exercised regularly.

2) Cancer Prevention Animal studies have shown that trans reservatol has a potent anti-cancer effect; and human studies are ongoing. In mice, the drug inhibited many different types of cancers. The effect was the strongest for tumors that came into direct contact with it, such as skin cancers and other cases when it was injected directly into tumours. However significant effects were also observed for Resveratrol capsules. The dosage varied depending on the study. As with any cancer studies - animal results do not always mean the same effect occurs for humans. However the animal results are encouraging.

3) Energy and Weight Loss Experiments have shown that the supplements give higher endurance and energy levels. The increase in metabolism, combined with the antioxidant effect, is a potent help with weight loss.

4) Alzheimer's Protection Researchers at Cornell University found that Resveratrol extract gives significant protection to the brain, preventing the formation of the protein "plaques" that are thought to cause Alzheimer's disease (senility). Based on these studies, It is thought that oral doses (such as capsules) help protect the brain from age related changes.

Which Reservatrol brand is best?

Resveratrol is found primarily in wine and grape juice, grapes of course, peanuts, and Japanese Knotweed. It was first brought to the attention of scientists when considering the "french paradox" - the fact that people in the south of France are generally healthy, with a low incidence of heart disease and cancer - despite having quite a fatty diet. Rezveratrol turned out to be the active ingredient. Initial studies with bacteria first showed its life extension abilities; and animal studies soon followed.
