An international unit (IU) is an internationally
accepted amount of a substance. This type of measure is used for the fat-soluble
vitamins (such as vitamins A, D and E) and certain hormones, enzymes, and biologicals
(such as vaccines).
The definition of an international unit (IU) is generally arbitrary, technical,
and eminently forgettable. For example, an IU of vitamin E is the specific biological
activity of 0.671 milligrams of d-alpha-tocopherol. Nonetheless, most IUs are quite
handy and helpful in use as a means of standardizing measures.
All international units are officially defined by the International Conference
for Unification of Formulae.
