Antioxidants are substances that inhibit or prevent oxidation of other molecules. Oxidation reactions can produce free radicals that can damage cells and tissues in the body. Antioxidants work by neutralizing free radicals and reducing the damage they can cause. They are commonly used in food, cosmetic, and pharmaceutical industries to prevent spoilage and extend the shelf life of products. Some examples of common antioxidants include vitamin C, vitamin E, beta-carotene, selenium, and zinc.
