Vitamins A, D and E are fat-soluble vitamins measured in international units. An international unit, or IU, is used to measure fat-soluble vitamins. Vitamins A, D and E are measured using international units to calculate recommended intakes, deficiencies and toxicities for healthy people. Recommendations vary based on age and gender.
International Units (IU) are an old terminology used to state the potency of vitamins A, D and E before vitamins were manufactured in a pure enough form to be measured by weight. One IU of Vitamin A = 0.3 micrograms. One IU of Vitamin D = 0.025 micrograms. One IU of Vitamin E = 0.67 milligrams.
