You likely meant 1000 IU of D. The tolerable upper limit of D is much higher than 1000 IU.
1 IU vitamin A Palmitate = 0.55 mcg Ex: 100 IU vitamin A Palmitate = 55 mcg ie multiply the IU by 0.55
The upper limit is about 10,000 IU/day, so 50,000 IU/week which is equal to about 7,000 IU/day.
10,000 IU of vitamin A is equivalent to 3,000 mcg.
30.12 mgFom IU to mcg: 50000 IU/1.66 = 30120 mcgFrom mcg to mg: 30120 mcg/1000 = 30.12 mg Final AnswerFrom USDATo convert Vitamin A as beta-carotene:From IU to mcg: IU/1.66 = mcgFrom mcg to IU: mcg * 1.66 = IUSource http://dietarysupplementdatabase.usda.nih.gov/ingredient_calculator/help.php#q2Ther are 1000 mcg in a mg so to convert to miligrams you have to divide the micograms by 1000.
3500 IU is equal to 1050 mcg (microgram) retinol (Vitamin A)
The international unit (IU) is not a measure of mass but only a measure of the drug effect.
1000 IU Vitamin D = 25 mcg Vitamin D = 0.025 mg Vitmain D. to convert IU of vitamin D divide by 40 to get mcg, divide by 40,000 to get mg. The minimum daily requirements for vitamin D have been markedly increased recently, and there is great confusion since the commercial products are still labeled as IU (International Units) while the research papers are stated in units of ug (micrograms) and mg. I spotted many unanswered questions regarding this conversion factor. *I need conversion to/from a measure that looks like ug, where the u has a tail like a lower case p. Is this the same as IU or what? How much is 100 u(plustail)g Vitamin D?
