Discussion: Research suggests that Grape Seed Extract is highly bioavailable and may provide greater antioxidant activity than vitamins C, E or beta carotene. Oligomeric proanthocyanidins (OPCs) are antioxidants that occur naturally in grape seeds. The OPCs in this product are provided in a synergistic base of bioflavonoids.
