What Is Resveratrol?
Resveratrol is a plant compound that acts like an antioxidant. The top food sources include red wine, grapes, some berries and peanuts.
This compound tends to be concentrated mostly in the skins and seeds of grapes and berries. These parts of the grape are included in the fermentation of red wine, hence its particularly high concentration of resveratrol.
However, much of the research on resveratrol has been done in animals and test tubes using high amounts of the compound.
Of the limited research in humans, most has focused on supplemental forms of the compound, in concentrations higher than those you could get through food.
