Usually this form of expressing quantity is used for fat-soluble vitamins and some hormones, enzymes, and biologicals such as vaccines. These units are defined by the International Conference for Unification of Formulae.A standard measurement of an antibiotic, vitamin, enzyme, or hormone, the amount of which produces a specific biological result.A universally accepted benchmark that measures the functional potency of a specific biological element, like a vitamin.
