[Moderator: Anti-oxididant intake does not equate to aging slower or living longer. And resveratol people are far more interested in separating you from your money and ability to savor wine than they are in finding out what the actual long-term effects are on your health.

Actually, how resveratrol works is open to speculation, whether it's an antioxidant or not may be incidental to its function, but it was first researched in an attempt to understand "the French paradox". According to the same nutritionists who tell us that every cheeseburger is a heart attack on a bun, the French ought to be dying at an even even earlier age because they have loads more fat in their diets than we Americans do.
They are the ones who figured out the major difference between American and French diets is that the French grow up drinking red wine like we do drinking soft drinks. They quickly homed in on resveratrol as the candidate for the difference, giving it to flatworms and extending their lifespans by 30 - 50%, then lab rats in a drowning tank where old fat rats on resveratrol fought to keep afloat as long as young fit rats without it.
That it works in humans is pretty well accepted by the scientific community, but not as an antioxidant, but rather it having something to do with enhancing the ability of insulin to burn fat for energy (still under dispute).
I first found out about it here on PhysOrg, not by listening to health food store hippies who don't know squat about nutrition (or newspaper articles written by reporters who don't know squat, either).
The main mystery isn't whether it works, it's why it works in doses that are small in comparison to lab-rat-drowning experiments. (For those with delicate sensibilities, they don't actually let the rats drown.) Resveratrol tablets may well make up the majority of Ray Kurzweil's 250 pills per day. In $1/day doses, you're getting more resveratrol than the French are in red wine, but less than the drowning rats per kg of body weight. I'd tell you where I get mine, but then I'd get accused of selling snake oil, so find your best deal yourself. (I also read about white tea here at PhysOrg in the last couple of weeks.)
