Regulation of food and dietary supplements by the U.S. Food and Drug Administration

The regulation of food and dietary supplements by the U.S. Food and Drug Administration is governed by various statutes enacted by the United States Congress and interpreted by the U.S. Food and Drug Administration ("FDA"). Pursuant to the Federal Food, Drug, and Cosmetic Act ("the Act") and accompanying legislation, the FDA has authority to oversee the quality of substances sold as food in the United States, and to monitor claims made in the labeling about both the composition and the health benefits of foods.

Substances which the FDA regulates as food are subdivided into various categories, including foods, food additives, added substances (man-made substances which are not intentionally introduced into food, but nevertheless end up in it), and dietary supplements. The specific standards which the FDA exercises differ from one category to the next. Furthermore, the FDA has been granted a variety of means by which it can address violations of the standards for a given category of substances.

The was the first of a series of significant consumer protection laws enacted by the Federal Government in the twentieth century and led to the creation of the Food and Drug Administration. Its main purpose was to ban foreign and interstate traffic in adulterated or mislabeled food and drug products, and it directed the U.S. Bureau of Chemistry to inspect products and refer offenders to prosecutors. It required that active ingredients be placed on the label of a drug’s packaging and that drugs could not fall below purity levels established by The United States Pharmacopeia or The National Formulary. The Jungle by Upton Sinclair was an inspirational piece that kept the public's attention on the important issue of unsanitary meat processing plants that later formed the Pure Food and Drug Act.
