According to Food and Nutrition Board (FNB) at the Institute of Medicine of The National Academies (formerly National Academy of Sciences) Vitamin D 1mcg = 40IU
10,000 IU of vitamin A is equivalent to 3,000 mcg.
The conversion rate for vitamin E acetate to IU is 1 IU = 0.67 mg. Therefore, 30 IU of vitamin E would be approximately equal to 20 mg of vitamin E acetate.
400 IU of vitamin D is equivalent to 10 micrograms (mcg) or 0.01 milligrams (mg).
Recalculate it from the IU-definition for VitA, but be sure the difference betweenretinol (C20H30O) and β-carotene (C40H56), both can be taken to be Vitamin A!By definition for Vitamin A:1 IU vitamin A is the biological equivalent of 0.3 μg retinol, or of 0.6 μg β-caroteneExamples:6 μg of dietary β-carotene is equivalent to 3⅓ IU of vitamin A and is equivalent to 3⅓ IU of vitamin A.This same amount also supplies the equivalent of 1 μg of retinol (or 1 RE =Retinol Equivalent) and is also equivalent to 3⅓ IU of vitamin A.So 5000 IU is 1500 μg retinol or 3000 μg β-carotene
There are 50 micrograms in 2000 IU of vitamin D.
10,000 IU of vitamin A is equivalent to 3,000 mcg.
1 IU is the biological equivalent of about 0.667 mg d-alpha-tocopherol (2/3 mg exactly), or of 1 mg of dl-alpha-tocopherol acetate
IU stands for Internation Unit, which is a unit of measurement. However it is based on the affect not a actual measurement. It is commonly used in pharmacy for some medication, vaccines, vitamins and hormones. The amount of the IU is regulated by an internation agreement for each substance. It is monitored by the Committee on Biological Standardization of the World Health Organization. The thing to remember is that 1 IU of vitamin B is not going to be the same as 1 IU of vitamin E.
1 IU vitamin A Palmitate = 0.55 mcg Ex: 100 IU vitamin A Palmitate = 55 mcg ie multiply the IU by 0.55
Is a 1000 IU Vitamin D the same as 1000 mg of Vitamin D
The conversion rate for vitamin E acetate to IU is 1 IU = 0.67 mg. Therefore, 30 IU of vitamin E would be approximately equal to 20 mg of vitamin E acetate.
3500 IU is equal to 1050 mcg (microgram) retinol (Vitamin A)
400 IU of vitamin D is equivalent to 10 micrograms (mcg) or 0.01 milligrams (mg).

There are 50 micrograms in 2000 IU of vitamin D.
No. 2,000 IU is a very modest dose - which can be taken daily. However, vitamin D is a fat-soluble vitamin, and should not be taken in excess.
