Description: Grape Seed Extract (50mg) - Twinlab OPC is the scientific name of an antioxidant complex derived from various plants especially grape seeds and pine bark (Pycnogenol). OPC stands for aligomeric proanthocyanidin, a class of extremely potent antioxidant compounds. Many experts believe that the OPSs in red wine explain the French paradox that is, that the French enjoy relatively low rates of heart disease despite a diet high in saturated fat. OPCs are believed to help prevent the oxidation of blood fats and cholesterol upon which much arterial heart disease is blamed. OPCs are important to skin care because they protect collagen from free radicals, dampen inflammation, and help maintain the health and integrity of blood vessels. As years go by, capillaries and veins become fragile, resulting in a decline in blood circulation. (In France, grape seed OPC is an approved prescription drug for treating weak blood vessels.) Preserving the blood vessels improves oxygen and food delivery to skin cells, which stimulates their growth and repair. Additional Benefits: Blocks the key enzymes that degrade collagen and other connective tissues Now believed to be the key factor in the cardiovascular health-promoting powers of red wine Neutralizes xanthine oxidase (a major generator of free radicals), and prevents oxidation of body fats and cholesterol Directions: As a dietary supplement for adults, take one capsule daily, preferably at mealtime.
