Body cells and tissues are threatened continuously by damage caused by toxic free radicals and reactiveoxygen species (e.g., peroxides) which are produced during normal oxygen metabolism, by other chemicalreactions and by toxic agents in the environment. Free radicals, once formed, are capable of disruptingmetabolic activity and cell structure. When this occurs, additional free radicals are produced, whichin turn can result in more extensive damage to cells and tissues. The uncontrolled production of freeradicals is thought to be a contributing factor to many degenerative pathologies.
The body's antioxidant defense system is more thanthe sum of its parts. That's because antioxidants depend on each other for ongoing effectiveness. Forexample, beta-carotene supports vitamin E, recognized as the body's most valuable fat soluble antioxidant. Itprevents oxidation of unsaturated fatty acids by inactivating free radicals, thus stabilizing andprotecting cell membranes, e.g. in the lungs, eyes, and arteries. Vitamin E can be regenerated by vitamin C.Vitamin C is a potent water-soluble antioxidant nutrient, also protecting cells from oxygen free radicaldamage. It is essential for connective tissue and bone metabolism, capillary health, and immune function.Vitamin C works together with vitamin E. When vitamin E is inactivated by neutralizing free radicals,vitamin C regenerates it back to full activity. In this process, however, vitamin C is oxidized and loses itsantioxidant activity.
As a cofactor of the antioxidant enzyme superoxide dismutase (SOD), zinc can be considered an antioxidantnutrient. Zinc supplementation has been shown to increase the antioxidant activity of SOD, and provideincreased free radical protection. Zinc deficiency is associated with increased oxidative damage.
Selenium is an essential cofactor of glutathione peroxidase, a potent antioxidant. Magnesium is involvedin energy metabolism, and is notably important in the heart, skeletal muscles, and nervous system.
