Antioxidants are substances that fight free radicals, which are compounds in the body that tamper with DNA and alter cells which sometimes lead to the cell's death. Free radicals naturally occur in the body as by-products of certain processes and environmental toxins, such as ultraviolet rays from the sun and air pollution. It is believed that free radicals contribute to the development of many health problems including heart disease and cancer, as well as the overall aging process. Antioxidants, such as the ones contained in this daily supplement, can reduce and possibly help prevent some of the damage they cause by neutralizing free radicals.
