Antioxidants protect the body from damage caused by harmful
molecules called oxygen free radicals. Some antioxidants are vitamins (such as
beta-carotene and vitamins E and C) that are naturally found in many fruits and
vegetables or are available as supplements.
Oxygen free radicals are normal by-products of cell metabolism.
But at high levels they can cause damage to cells. Antioxidants may
protect the body from cell damage.
