Zeisel SH. Regulation of nutraceuticals. Science 1999;285:1853-1855. Nutraceuticals are dietary supplements that deliver a concentrated form of a presumed bioactive agent originally derived from a food, now present in a nonfood matrix, and used to enhance health in dosages exceeding those that could be obtained from normal foods. Nutraceuticals do not require a prescription and their use is governed by the 1994 Dietary Supplement and Health Education Act, though more specific regulations that differentiate nutraceuticals from dietary supplements are needed.
