Is resveratrol, the putative anti-aging ingredient found in red wine, on the market yet?

Yes. There are a number of resveratrol products on the market as dietary supplements, but as with many such supplements, these products have not been rigorously tested or approved by the US Food and Drug Administration. Researchers at Sirtris Pharmaceuticals in Cambridge hope to have a real resveratrol drug (not a supplement) on the market to combat Type 2 diabetes and other illnesses by 2012.
