resveratrol

is a plant product that was first extracted from white hellebore.It is most coomonly isolated from Japanese knotweed.Resveratrol is found in

red wine

,white wines,pinot noir,the amount being maximum in red wine.It is also found in peanut,blueberries etc.

In animal experiments,Resveratrol has found to have some blood sugar lowering effect,anti-cancer,

antioxidant

and beneficial effects on heart.But these effects have not been established in human studies.In one study in mice it was found to have

anti aging

role.

Molecular studies have shown that it may have beneficial effects on stomach,esophagus,breast,skin,prostate cancer.But this beneficial effects are not possible even with the largest dose.

The side effects have not been established in any study.But eminent authors suggest that resveratrol should not be taken by pregnant women as this compound is estrogenic.This should also not be taken by children and individuals less than 18.
Potential benefits that have been observed in animal studies are it increases the speed of metabolism,thus helping to burn the calories.It has also been shown to be beneficial in alzheimer’s disease and other neuro degenerative diseases by reducing the amyloid plaque formation in the brain.But as mentioned before,these have not been proved in human studies.

It has been proposed that absorption of
resveratrol supplements
may be best from the mucosa of the stomach.

I have tried to post a comprehensive review about resveratrol,but do consult other reliable internet resources,and obviously consult your doctor.
