Resveratrol at 10 Times a Realistic Dose Only Extends Worms' Life by 4%
Resveratrol has gotten a lot of press as a life-extender, mostly because people love an excuse to consume red wine and dark chocolate. But the expected effect of a heroically resveratrol-heavy diet on humans is probably so small as to be practically undetectable. Even in concentrated pill form, the quantity that would be equivalent to what extends nematode lifespan by 4% would be difficult to consume (and presently quite expensive). Just enjoy the placebo effect when you munch on your dark chocolate bar and sip your red wine. (thanks, gwern)
