Yes, the antioxidant present in red wine and grapes has been linked to cancer in a recent Oregon Health & Science University study. This doesn’t mean that you have to stop drinking red wine or grapes, but most definitely cautions against large doses that exist in supplements.

PERQUE has never recommended pharmacological doses of resveratrol.
