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 adults, the recommended daily value of vitamin D is 600 International Units (IU) or 15 micrograms (mcg). It is likely that a doctor will recommend between 400 and 1,000 IU per day to supplement your diet for a short period of time.
