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.
Vitamin D promotes calcium absorption, and it is needed for bone growth. It also has a positive role in the function of the immune system and reduces inflammation. Women aged 19 to 70, pregnant or nursing are required to get 600 international units, or 15 micrograms, of vitamin D. After age 70, the RDA for vitamin D is 800 IU, or 20 micrograms.
