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.
For example, 1 IU of vitamin E is equivalent to 0.66 milligrams of delta-alpha-tocopherol or 1 milligram of alpha-tocopherol acetate. Alpha-tocopherol vitamin E is the one with the most bioavailability in humans and you need 22.4 IU of this form of vitamin E daily.
