Life Extension’s Whole Grape Extract has been formulated to provide high levels of standardized proanthocyanidins found in grape seed and skins. These proanthocyanidins and flavonoids are rapidly absorbed and distributed throughout the body, helping to eliminate free radicals while supporting healthy collagen.172-175 This is of particular importance in protecting the underlying supporting structure of the skin.
Unlike competitive products that contain only proanthocyanidins, this blend also provides standardized trans-resveratrol and a whole red wine polyphenol extract.
Resveratrol is a phytoalexin, a polyphenolic compound which is produced by Vitis vinifera as a response to attack by molds. Findings from published scientific literature indicate that resveratrol may be the most effective compound for maintaining optimal health and promoting longevity.144
Research funded by the Life Extension Foundation showed that a combination of low-dose (20 mg) resveratrol plus grapeseed extract mimicked many of the favorable gene expression changes seen in calorie-restricted animals.
