Grape Pips Proanthocyanidins

Grape Pips Proanthocyanidins contain flavonol proanthocyanidin extract from grape seeds, which provides powerful antioxidant activity against peroxyl free radicals and supports capillary integrity.* Our high-quality raw material contains not less than 95% total polyphenols including 83% oligomeric proanthocyanidins. Grape seed proanthocyanidins were originally discovered and patented by the same researcher who discovered pycnogenol in pine bark extract which is the main phenolic antioxidant found in red wine. They have undergone extensive clinical and toxicological studies, and exhibit powerful antioxidant activity, due to their diphenol components and related structures.*
