It is mainly composed of polyphenols such as proanthocyanidins, catechins, epicatechin, gallic acid, and epicatechin gallate. Grape seed extract is a purely natural substance and one of the most efficient antioxidants derived from plants found so far. Tests have shown that its antioxidant effect is 30 to 50 times that of vitamin C and vitamin E. Proanthocyanidins have extremely strong activity and can inhibit carcinogens in cigarettes. Their ability to capture free radicals in the water phase is 2 to 7 times that of general antioxidants. For example, it is more than twice as active as α-tocopherol.
