Wine ingredient resveratrol as anti-aging pill? Not just yet

Today’s USA Today

“Because grapes are pricey and the pulp yields relatively low levels of the compound, some supplement companies instead make an extract from grape seed and grape skin. These extracts are “high in other polyphenols but not actually in resveratrol,” says Andrew Shao of the Council for Responsible Nutrition, a supplement industry trade association.

“Drinking a glass or two of red wine won’t give the levels of resveratrol studied, Sinclair says. It would be impossible to drink enough red wine daily to reach them. “The analogy would be if when they discovered penicillin, everyone was focused on drinking 20 gallons of mold juice.”
