What is an antioxidant? An antioxidant is a compound that helps to neutralize harmful molecules called free radicals. Free radicals are unstable molecules that can damage cells and contribute to the development of chronic diseases such as cancer, heart disease, and Alzheimer’s disease.
Antioxidants work by donating an electron to neutralize the free radical, thus preventing it from causing damage to cells. Antioxidants can be found naturally in fruits, vegetables, and other foods, as well as in dietary supplements. Some examples of antioxidants include Vitamin C, Vitamin E, beta-carotene, and selenium.
