Antioxidants Antioxidants are substances that slow oxidation by neutralizing free radicals. Free radicals are unstable molecules that can oxidize, or damage, other molecules. The more LDL cholesterol absorbed the greater the risk of formation of plaques and narrowed arteries. Therefore, in theory, antioxidants may reduce the risk of heart disease. Vitamin E, vitamin C, beta carotene and coenzyme Q-10 are antioxidants.
Vitamin E is a potent antioxidant that helps prevent damage from free radicals.
Some studies show that vitamin E might prevent or slow progression of plaque formation if you already have heart disease. Although there is probably little harm in taking vitamin E, there is not enough evidence to recommend vitamin E supplements for the general population. Consult your doctor before you start. Side effects of vitamin E supplementation are generally rare. Don't take vitamin E supplements if you are taking blood-thinning medication.
