Resvida is a high-potency resveratrol for healthy aging. A polyphenol found in the skin of grapes, resveratrol is believed to be responsible for many of the health benefits associated with red wine. As a powerful antioxidant, it provides demonstrated health benefits for the heart, the brain and the muscles. More recently, resveratrol has been shown to mimic caloric restriction, the only proven scientific way to extend life in mammals. Resvida is produced in the vendor’s GMP facilities in Europe, in compliance with the strictest safety, health and environmental standards. Most other resveratrol in the market is extracted from the roots and stalks of the giant knotweed plant (Polygonum cuspidatum) in China, the company claims.
