Antioxidants are nutrients such as vitamins and minerals, and enzymes that are capable of counteracting the damaging, but normal, effects of the physiological process of oxidation in bodily tissues. Antioxidants work in two ways, chain breaking and prevention. A chain-breaking antioxidant such as vitamins A, C and E, stabilise free radicals or cause them to decay into harmless atomic structures. Isotonix OPC-3 is an isotonic-capable food supplement that is made from a combination of bilberry, grape seed, red wine, pine bark extracts and citrus bioflavonoid complex, all found to be potent antioxidants. Oligomeric proanthocyanidins (OPCs) are bioflavonoids (complex organic plant compounds) found in fruits, vegetables and certain tree barks that provide nutritional benefits to the human body. Studies have shown OPCs to be more powerful than vitamin C and vitamin E in neutralising free radicals. Isotonix OPC-3 is the leading isotonic product to contain Pycnogenol ™ in the world. Pycnogenol is a natural plant extract from the bark of the French maritime pine tree and the most researched bioflavonoid.
