Product Information

Oligomeric proanthocyanidins (OPCs) are comprised of two, three, or more flavonoid molecules attached to each other. OPCs demonstrate important vascular-protective effects.* OPCs also have strong free-radical scavenging ability, resulting in inhibition of oxidative stress and protection of blood vessels and other tissues.* OPCs have been shown to inhibit oxidation of LDL cholesterol and to protect vascular endothelial cells (cells lining the inside of arteries).* OPCs also appear to strengthen the resistance of cell membranes to injury.*

OPCs may have a vitamin E-sparing effect. 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 (vitamin E) in red blood cell membranes.*

Evidence suggests OPCs stabilize collagen cross-linkage within the skin and connective tissues, thus improving the strength of the connective tissue.* OPCs have also been shown to decrease capillary permeability (thus decreasing bruising) and block the effects of hyaluronidase, elastase, collagenase, and other enzymes that can degrade connective tissue.* Studies demonstrate reduced swelling and improved healing time from sports injuries in athletes given OPCs prior to a sporting event.*
