FDA issues guidance on antioxidants. The US Food and Drug Administration (FDA) has published guidance to help small companies comply with the labeling of antioxidant products and high potency products. The Small Entity Compliance Guide sets out the agencyâs position âin plain languageâ regarding the use of the nutrient content claims on dietary supplement products.
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions. The term antioxidant is mainly used for two different groups of substances: industrial chemicals which are added to products to prevent oxidation, and natural chemicals found in foods and body tissue which are said to have beneficial health effects.
