Grape Seed Extract: A Powerful Antioxidant
Grape seed extract is a natural plant substance that has a concentrated source of oligomeric proanthocyanidins (OPC). These antioxidants help protect cells from free radical damage and also promote healthy circulation. Grape seed extract is rich in polyphenols, a compound that is high in antioxidants. Studies have shown OPC to be more powerful antioxidants than Vitamin C, Vitamin E and beta-carotene.
Grape seed extract has been shown to remain in the body for as long as three full days, and is 20 times more potent than vitamin C and 50 times more potent than vitamin E.
