Our bodies naturally suppress free radicals with Vitamins A, C, E and the mineral Selenium. These antioxidants work together to neutralize highly reactive molecules. Even a balanced diet may not provide all of the antioxidants the body will use. ACES provide the body with armament for a four-point attack. Beta-Carotene quenches single oxygen molecules. Vitamin C protects tissue and blood components. Vitamin E protects cell membranes. Selenium is a vital building block in the structure of glutathione peroxidase, one of the body's antioxidant enzymes. Research indicates that together these nutrients are more effective than when taken individually.
