Researchers do not know for certain how -- or if -- resveratrol affects aging. The compound, which is found primarily in red wine and other plant products, has shown some promise in preventing age-related problems like heart disease, cancer and osteoporosis, but more research is needed.
Scientists say there are several ways resveratrol might have an anti-aging effect. One is that the compound is an antioxidant, so it could protect cells from damage by molecules called free radicals. Resveratrol also has anti-inflammatory effects.
In studies in animals, resveratrol has shown protective effects on the heart and blood vessels. However, researchers don't know whether it's effective when taken as a supplement.
