Supplement & Drug Dosage Converter
Convert supplement and drug dosing between milligrams (mg), micrograms (mcg), and International Units (IU) based on specific substances.
International Units (IU) are used to measure the biological effect of fat-soluble vitamins (A, D, E) and certain hormones, rather than physical mass.
Vitamin D3: 1 mcg is exactly 40 IU. Thus, 50 mcg (or 0.05 mg) represents 2000 IU, a standard daily nutritional value.
Vitamin E Natural vs. Synthetic: Natural (d-alpha-tocopherol) has higher biological potency per milligram than synthetic (dl-alpha-tocopherol), requiring fewer mg to reach the same IU value.
