Resveratrol is a natural compound classified as a polyphenol and is found in a variety of plants , including wine grapes , some wild berries , and peanut shells . It is known for its antioxidant properties, which help protect the body's cells from oxidative damage caused by free radicals .
One of the remarkable mechanisms of action of resveratrol is its ability to activate a certain group of enzymes called sirtuins . Sirtuins play a role in the regulation of cell lifespan and are associated with longevity . By activating sirtuins , resveratrol may help promote healthy aging and theoretically extend life . This mechanism has sparked interest in resveratrol's potential antiaging effects.
Resveratrol also metabolizes into another similar compound called pterostilbene , which is structurally similar to resveratrol and shares some of its beneficial properties . Pterostilbene has been studied for its potential to support cardiovascular health , cognitive function, and healthy aging . It may have similar antioxidant and anti-inflammatory effects.
Optimal amounts of resveratrol can vary and typically range from 100 to 500 milligrams per day. A well-balanced diet rich in fruits, vegetables and other plant foods can provide a natural source of resveratrol. However, supplementation can be considered for individuals who may not be getting sufficient amounts through their diet.
