Dietary supplement

A dietary supplement, also known as food supplement or nutritional supplement, is a preparation intended to provide nutrients, such as vitamins, minerals, fiber, fatty acids or amino acids, that are missing or are not consumed in sufficient quantity in a person's diet. Some countries define dietary supplements as foods, while in others they are defined as drugs.

Supplements containing vitamins or dietary minerals are included in the Codex Alimentarius Commission, a guidebook on food safety sponsored by the United Nations.
