Description: A dietary supplement to support vascular function and skin health.* Our Grape Seed Extract is standardized to yield 95 mg (95%) proanthocyanidins (PCOs) per 100 mg capsule and 47.5 mg (95%) proanthocyanidins per 50 mg capsule. PCOs are a special class of water soluble bioflavonoids that are potent antioxidants.* PCOs prevent the release of histamine from mast cells thereby reducing the adverse effects of histamine.* PCOs support capillary strength.* Weak capillaries can contribute to bruising, elastin and collagen dysfunction, edema, and circulatory insufficiencies.
