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 international unit (IU) is not a measure of mass but only a measure of the drug effect.
Yes, 400 iu of vitamin e a day is perfectly reasonable. Especially if you are active.
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
IU is not a measurement of mass or weight like others but ti is the measurement of potency of a drug such as...vitamin capsules. =)
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
1 IU vitamin A Palmitate = 0.55 mcg Ex: 100 IU vitamin A Palmitate = 55 mcg ie multiply the IU by 0.55
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.
Is a 1000 IU Vitamin D the same as 1000 mg of Vitamin D
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.
IU is not a unit of mass, but a measure for biological activity. The mass of 1 IU is different for every substance. 1 IU of vitamin A is 0.3 micrograms 1 IU of vitamin B is 50 micrograms.
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.
Yes, 400 iu of vitamin e a day is perfectly reasonable. Especially if you are active.
