what does usp after a drug name mean
USP also conducts verification programs for dietary supplement products and ingredients. These are testing and audit programs. Products that meet the requirements of the program can display the USP Verified Dietary Supplement Mark on their labels. This is different from seeing the letters "USP" alone on a dietary supplement label, which means that the manufacturer is claiming to adhere to USP standards. USP does not test such products as it does with USP Verified products.
