Anitoxidants are supplements which supply substances that can slow or completely prevent the oxidation of other molecules. Oxidation is the process that causes free radicals, which then damage cells. Antioxidants have been reported and used for a wide variety of health and wellness functions, such as treating injury to the brain, preventing heart disease, macular degeneration, diabetes, neurological problems, and possibly even reduce the risk of cancer, and reduce muscular weakness during exercise. Antioxidants can not only slow the oxidation process, but can repair some of the damage done by the free radicals produced. Antioxidants are so effective at maintaining health and wellbeing that they have even been referred to as anti-aging products, due to their effect on creating healthy skin and nails.
