Oligomeric proanthocyanidins (OPCs) are comprised of two, three, or more flavonoid molecules attached to each other. OPCs have strong free-radical scavenging (antioxidant) ability, resulting in inhibition of oxidative damage and protection of blood vessels and other tissues. OPCs have been shown to protect vascular endothelial cells from oxidative damage and appear to strengthen the resistance of cell membranes to injury and degradation. They also bind copper and iron, thereby reducing their oxidative effects. A clinical study of 10 healthy volunteers examining the effect of OPC supplementation on markers of oxidative stress showed significantly increased levels of alpha-tocopherol in red blood cell membranes.Evidence suggests OPCs stabilize collagen cross-linkage within skin and other connective tissues. OPCs have also been shown to decrease capillary permeability (thus decreasing bruising). Clinical studies demonstrate reduced swelling and improved resolution of sports injuries in athletes given OPCs prior to a sporting event.OPC provided as a phytosome for enhanced absorptiona potent flavonoid antioxidantpromotes vascular strengthpromotes optimal eye healthThese statements have not been evaluated by the Food and Drug Administration (FDA).
