The original person who answered this stated it was 400IU...This is wrong and could possibly be a grave mistake if someone were to follow this crap answer. each ONE mg = 40,000 IU whoever answered this is playing around in things they shouldn't touch. 4000 mg would be 160,000,000 IU and would be a fatal dose of vitamin D. ALWAYS go look for other answers before you trust the first thing you find people.
1000 IU = 25 micrograms
4000 IU = 100 micrograms
This is the same as 0.1 milligrams
However, vitamin D is usually expressed in micrograms, not milligrams. For example, the European Recommended Daily Allowance is 5 micrograms
1 mg=approx 2.7 iu. You will see this rounded to a 1:3 ratio for rHGH and Insulin. To answer your question let's say 1 gram of liquid D = 2700-3000 iu. human chorionic gonatotropin comes in 250-10,000 iu per cc in. Powder or so that makes sense. 1000 mg=1 gram. Just to be clear.
100 mg
10,000 IU of vitamin A is equivalent to 3,000 mcg.
3500 IU is equal to 1050 mcg (microgram) retinol (Vitamin A)
100,000 IU
500
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
20 milligrams.
Is a 1000 IU Vitamin D the same as 1000 mg of Vitamin D
Ans: 0.3 mg = 1,200 i.u...... 1 mg = 40,000 iu
50000 iu
how can convert 100 mcg B12 in mg
