Quick-reference compound profiles, dosage ranges, and interaction notes. Your go-to stimulant database.
Labels mix micrograms, milligrams and international units, and IU means something different for every vitamin. Enter an amount to convert it, including the official IU factors for vitamins A, D and E.
Metric conversions are exact: 1 gram is 1000 milligrams and 1 milligram is 1000 micrograms. IU factors are the official ones: 1 IU of vitamin D equals 0.025 mcg, 1 IU of retinol equals 0.3 mcg RAE, 1 IU of natural vitamin E equals 0.67 mg and 1 IU of synthetic vitamin E equals 0.45 mg. IU is meaningless without knowing which nutrient it describes.
B vitamins get grouped together on labels as though they were interchangeable, but their reference amounts differ by more than tenfold.
Daily Values are the FDA labelling reference for adults and children 4 years and older. B12 and folate are omitted here because they are measured in micrograms and would not be visible at this scale.
