1 iu how much mg

Commonly, people want to work out the amount of micrograms or milligrams in a medication or vitamin supplement. I think that people wonder why the International unit isn't in the lists featured in the mass and weight converter. The reason for this is that the conversion isn't as simple as one might think.

Let's start this article by discussing what an International unit is. IU stands for International units and is a unit commonly used in the measurement of medications, vaccines and vitamins. The volume or mass that makes up one International unit is dependent on the concentration or potency of the substance and therefore varies from substance to substance depending on what is being measured.

This means that converting between international units and micrograms or milligrams is not a simple calculation and we can't provide a converter to do this calculation for you sorry about that. The exact measure of one IU of a substance is in fact established by international agreement for each substance 1. If you want to find out how many micrograms mcg or milligrams mg are in one IU of your medication, you could contact your pharmacist to find out.

As an alternative, you could try contacting the drug manufacturer directly. For a vitamin, consider contacting the vitamin manufacturer - their contact information is usually listed on the bottle. We've included mass equivalents of 1 IU for selected vitamins below. To convert this to mcg, using the information above, I would multiply it by 0.

Taking excessive dosages of fat-soluble vitamins can have a toxic effect because they linger in the body for longer periods of time and cannot easily be purged. Supplement labels provide a recommended dietary allowance RDA to inform consumers of the average amount of a specific vitamin they should consume daily.

The RDA varies according to age and gender because each stage of life and gender has its own nutritional requirements. Unless otherwise specified, the RDA on a supplement label refers to both genders older than four years. Vitamin A: There are two widely available preparations of vitamin A: retinol and beta carotene. The IU equivalent of vitamin A in the retinol format is 0. The value for beta carotene is 0. Converted to milligrams, this amount equals 0.

Vitamin E: Vitamin E is available in two formats: d-alpha-tocopherol, a natural source, and dl-alpha-tocopherol, a synthetic source. One IU of d-alpha-tocopherol equals 0. The dl-alpha-tocopherol formulation contains 0. The RDA for an adult is Vitamin D: The most commonly available vitamin D preparation is vitamin D3, or cholecalciferol.

Using milligrams changes the value range to 0.
