Nascobal

This latter fact has caused some people (usually from reading labels on packages and vitamin supplements, in which vitamin B-12 is almost always listed last, since ingredients by law are listed in order of weight�%), to infer that the "correct" chemical name of vitamin B-12 actually IS cyanocobalamin. In fact, "vitamin B-12" is the name for a whole class of chemicals with B-12 activity, and "cyanocobalamin" is only one of these. Cyanocobalamin usually does not even occur in nature, and cyanocobalamin is not one of the forms of this vitamin which is directly used in the human body (or that of any other animal). However, animals and humans can convert it to active (cofactor) forms of the vitamin, such as methylcobalamin.[1]
