Grape Seed Extract is known as a powerful antioxidant. Antioxidant protection helps protect the body from premature aging, disease and decay. Antioxidants are needed to neutralize free radicals. Free radicals play a major role in the development of degenerative diseases, cardiovascular diseases, strokes and aging. The antioxidant capacity of grape seed extract comes from proanthocyanidins (oligomeric proanthocyanidins) (OPCs). Scientific studies have shown that proanthocyanidins antioxidant power is 20 times stronger than Vitamin C and 50 times stronger than Vitamin E.
