Incidentally, I understand why some people might think this is a scam. I think they're wrong, but I understand why they would say that. I'm no biochemist myself, but as I understand it, there isn't much debate any longer that free radicals are bad for us and/or that anti-oxidants neutralize them. Nor is there much question that ingestion of antioxidants is a pretty inefficient way to increase the their levels in our bodies. McCord seems to be a legitimate researcher, and this approach seems to be promising.
Good question -- maybe there's a way to e-mail him and ask? If you find out, please let me know.
