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.
The results of this study indicate that supplementation with 2000 IU/day is required beginning in gestation and during the first 8 weeks of breastfeeding to protect 98% of un-supplemented infants against vitamin D deficiency. Nearly half of un-supplemented infants of mothers taking 400 IU/day were vitamin D deficient after 8 weeks of breastfeeding.
