| http://www.w3.org/ns/prov#value | - The Food and Drug Administration (FDA) defines a supplement broadly, as an ingestible product containing a ???dietary ingredient,??? which may include vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, glandulars and metabolites.That practically means anything from plain old Vitamin C to exotic stuff like L-carnitine.
