Definition: According to the Dietary Supplement Health and Education Act (DSHEA) of 1994, a dietary supplement is any product that contains substances like vitamins, minerals, foods, botanicals, amino acids and is intended to supplement the usual intake of these substances. Dietary supplements are found in pill, tablet, capsule, powder or liquid form and are meant to be taken by mouth. Dietary supplements have potential risks and possible benefits because they're not well regulated and standardization is not required.
