There are sound theoretical reasons to think that antioxidant ingestion ought to be good for you and the antioxidants in your body are certainly important. But all the research I've seen on the matter is that ingesting extra antioxidants has the opposite of the effect you'd expect. I'd guess this is some homeostasis related interaction but I don't think anybody actually knows why.
