Hi,

 

I think this varies (IU to mg) that is to say the amount of

mg per IU is dependent upon the vitamin or drug of which

you speak. See definition below from web page noted

below that.

 

" international unit (IU)

a unit used to measure the activity (that is, the effect) of many vitamins

and drugs. For each substance to which this unit applies, there is an

international agreement specifying the biological effect expected with a dose of

1 IU. Other quantities of the substance are then expressed as multiples of this

standard. Examples: 1 IU represents 45.5 micrograms of a standard preparation of

insulin or 0.6 microgram of a standard preparation of penicillin. Consumers most

often see IU's on the labels of vitamin packages: in standard preparations the

equivalent of 1 IU is 0.3 microgram (0.0003 mg) for vitamin A, 50 micrograms

(0.05 mg) for vitamin C, 25 nanograms (0.000 025 mg) for vitamin D, and 2/3

milligram for (natural) vitamin E. Please note: for many substances there is no

definite conversion between international units and mass units (such as

milligrams). This is because preparations of those substances vary in activity,

so that the effect per milligram of one preparation is different from that of

another. "
