Antioxidants What is it? (physiology and clinical effects) Antioxidants are compounds that protect the body from cellular damage caused by free radicals. Free radicals are a major cause of disease and aging. They are formed by exposure to toxic chemicals, such as cigarette smoke, polluted air, industrial chemicals, radiation and the sun's rays, as well as from various metabolic processes, such as breaking down fat cells for energy use. The body has several enzymes to help neutralize the free radicals. There are also certain nutrients that are powerful antioxidant, such as vitamin A, C, and E, beta-carotene, flavonoids, selenium, alpha lipoic acid, coenzyme Q10, glutathione, and herbs such as bilberry, curcumin, garlic, ginkgo biloba, and green tea.
