Antioxidants supplements are popular in part because fruits and vegetables which are rich in antioxidants are associated with many health benefits. These include reduced risk of disease. Antioxidants can be man-made, or natural, and may prevent or delay some types of cell damage. Diets high in fruits and vegetables, which are rich in antioxidants, have been found to be healthy. If you aren't getting enough from your diet, you may want to look into supplementing with supplements rich in antioxidants and free radicals.
