1 ng is 0.04 IU. So, to convert 12.5 microgram, multiply 12500 nanogram with 0.04; the required answer is 500 IU
Alfacalcidol is a vitamin D analog, and its potency is generally measured in micrograms (mcg) rather than international units (IU). However, 1 mcg of vitamin D is equivalent to approximately 40 IU. Therefore, 0.25 mcg of Alfacalcidol would be roughly equivalent to 10 IU of vitamin D.
There is no direct conversion between milligrams (mg) and International Units (IU) for vitamin D because they measure different aspects of the nutrient. However, a common conversion for vitamin D3 is 1 microgram (µg) = 40 IU. So, you would need to convert the 1.25 mg dosage to micrograms and then calculate the equivalent IU based on this conversion factor.
1 mcg vitamin D (cholecalciferol) = 40 IU Let´s say you have 300 IU of vitamin D: 300 / 40 = 7,5 mcg vit. D Then you would have to convert 7,5 mcg to mg: 7,5 / 1000 = 0,0075 mg vitamin D.
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
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?
The conversion factor for International Units (IU) to milligrams (mg) varies depending on the substance being measured. For Vitamin D, the conversion factor is typically 40 IU to 1 mcg (microgram) or 1000 IU to 25 mcg. Therefore, to convert 500,000 IU of Vitamin D to milligrams, you would divide by 40 to get 12,500 mg or divide by 25 to get 20,000 mg, depending on the specific conversion factor used.
vit D and calcium
Ans: 0.3 mg = 1,200 i.u...... 1 mg = 40,000 iu
An International Unit (IU) is a standardized measurement used to quantify vitamins A, D, and E. The conversion to micrograms (mcg) or milligrams (mg) varies for each vitamin. For vitamin A, 1 IU is equivalent to 0.3 mcg retinol. For vitamin D, 1 IU is equivalent to 0.025 mcg cholecalciferol. For vitamin E, 1 IU is equivalent to 0.67 mg tocopherol.
IU stands for International Unit, which is a measurement typically used for vitamins and medications. The conversion of IU to milligrams depends on the specific substance being measured. For Vitamin D, 1 IU is equivalent to 0.025 micrograms. Therefore, 600 IU of Vitamin D would be equal to 15 micrograms or 0.015 milligrams.
Is a 1000 IU Vitamin D the same as 1000 mg of Vitamin D
