What Are Antioxidants?

Vitamins A, C, and E are often described as antioxidants. They are substances that prevent a chemical reaction called oxidation. Oxidation can produce chemicals that are very reactive and sometimes harmful to the cells in the body. Natural antioxidants such as vitamins A, C, and E work together to prevent oxidation and therefore have a protecting effect for body cells. The potential role of antioxidants in reducing the risk of heart disease, cancers, and cataracts is currently being studied.
