The Grapeseed Extract with Resveratrol Pterostilbene formula contains ingredients found in grape seed and skin. Grapeseed extract helps to maintain your cells healthy, supports healty blood flow and protects the central nervous system. This whole grape extract includes also compounds naturally found in red wine. For extra health benefits, this blend contains also trans-resveratrol and trans-pterostilbene that work synergistically for greater anti-ageing properties. Pterostilbene is a compound from the same family as resveratrol, called phytoalexins, which are found in small berry plants. In the scientific community resveratrol is considered to be the most effective compound for maintaining optimal health and promoting longevity. Research funded by the Life Extension Foundation showed that a combination of low-dose (20 mg) resveratrol plus grapeseed extract have increased life-span in animals, by mimicking a low-calorie diet.
