Sorry, but based on that analysis I have no idea. I’ve never seen a label report values in usp – nutrient values are typically reported in IU.
I found this:
“From the Dictionary of Units of Measurement:
USP unit:
a unit used in the United States to measure the mass of a vitamin or drug based on its expected biological effects. For each substance to which this unit applies, the U. S. Food and Drug Administration has determined the biological effect associated with a dose of 1 USP unit. Other quantities of the substance can then be expressed in terms of this standard unit. In most cases, the USP unit is equal to the international unit (IU). “USP” is an abbreviation for the United States Pharmacopeia, a handbook describing the established properties of drugs legal for use in American medicine.”
Some of these values look a little high to be equivalent to IU. I’m not sure though. I’d need to know IU equivalents for the reported values before I could say.
