Antioxidants are dietary supplements that contain substances that can slow down or completely prevent the oxidation of other molecules. Oxidation is the process that causes free radicals that then damage cells. Antioxidants have been reported and used for a variety of health and wellness functions, e.g. to treat brain damage, prevent heart disease, macular degeneration, diabetes, neurological problems and perhaps even reduce them. the risk of cancer and the reduction of muscle weakness during exercise. Antioxidants can not only slow down the oxidation process, but also repair some of the damage caused by the free radicals that are formed. Antioxidants are so effective in maintaining health and well-being that they have even been called anti-aging products because of their effect on healthy skin and nails.
