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.
I take 3,000 IU daily, but I skip it in the summer. I feel markedly better after I've taken about 1,000 IU consistently for over a week. Tolerable upper intake limit (that is, max to safely take every day) is listed on wikipedia at 4,000 IU for adults. Wikipedia tells me that Vitamin D is fat-soluble, not water-soluble.
