Does USP grade mean the producer is FDA approved?

No. USP grade means the lot meets the monograph tests. Whether a material can be used in a US drug product also depends on the manufacturing site, its registrations and the drug sponsor's own supplier qualification.

What is the difference between USP and USP Reference Standards?

USP grade describes a substance that meets the monograph. USP Reference Standards are highly characterised primary materials sold by USP itself for use in the tests that the monographs describe.

Is USP grade suitable for dietary supplements?

USP also publishes monographs for dietary supplement ingredients. Supplement makers often specify USP or FCC grades, depending on the ingredient and the claims they plan to make.
