A nutraceutical is defined as "a substance that is produced in purified or extracted form, administered orally to provide agents required for normal body structure and function with the intent of improving the health and well-being of animals" <ref>Anonymous. Council defines "nutraceutical." Journal of the American Veterinary Medical Association 1996; 209:1986.</ref>. Nutraceuticals are not regulated in the same way as pharmaceuticals and do not have to undergo the same rigorous testing to be approved. Efficacy has not been properly evaluated for most nutraceuticals.

However, only one of these studies included a control group, the inclusion criteria were very broad, the populations small and outcomes were measured using questionnaires that had not been validated or checked for test-retest reliability. More studies are required to confirm clinical efficacy.
