Viewpoint: High-dose resveratrol supplements to extend health and life? Don’t waste your money. Joe Schwarcz | July 27, 2026

https://geneticliteracyproject.org/2026/07/27/viewpoint-high-dose-resveratrol-supplements-to-extend-health-and-life-dont-waste-your-money/ A quick online search for “resveratrol supplements” finds dozens produced by various companies. They contain anywhere from 50 to 500 mg resveratrol per capsule and sport labels that scream “source of antioxidants.” But there is no mention of any condition that resveratrol is expected to treat or prevent. For good reason! While there is plenty of speculation about what this compound can do based on laboratory experiments that use cell cultures, yeasts, worms, flies or rodents, it is best to remember that humans are not giant test tubes or colossal rodents. Clinical evidence for any benefit of resveratrol supplements in people is sparse, but there are some interesting possibilities as researchers aim to develop special formulations of resveratrol that increase its absorption and therefore levels in the blood previously not achievable.
