Natural Factors RegenerLife Resveratrol - Offers a highly concentrated form of all-natural trans-resveratrol, a potent antioxidant to protect cells and tissues from oxidative damage that causes premature aging. Resveratrol helps protect blood vessels, brain cells, joint tissue, and skin, making it a superstar compound for whole-body health and longevity. Because cumulative cell damage from free radicals can speed up age-related decline, preventing free radical damage is important for maintaining optimal health throughout a person’s lifespan. Studies show that resveratrol enhances the body’s ability to resist oxidative stress, which may help protect against age-related health conditions and increase longevity. RegenerLife Resveratrol is sourced from grapes grown in the Okanagan Valley of British Columbia and Japanese knotweed.
