The dietary supplement section contains 200 monographs for vitamin-mineral combination products, botanicals and nonbotanicals used in almost 900 dietary supplements.

The USP-NF is the consolidation of two separate official compendia-the USP and the NF- to form one comprehensive resource. The USP contains legally recognized standards of identity, strength, quality, purity, packaging, and labeling for drug substances, dosage forms, and other therapeutic products. The National Formulary (NF) contains standards for products such as excipients.
USP-NF monographs contain specifications (tests, procedures, and acceptance criteria) that help ensure the strength, quality, and purity of named items. The USP-NF also contains monographs and general approaches to ensure the quality of compounded preparations. USP-NF monographs, which are recognized worldwide, may be enforceable by the U.S. Food and Drug Administration (FDA) and also by state agencies in the United States. The new USP 27-NF 22 is available in print, CD and online formats. For more information or to order the USP-NF, please call 1-800-227-8772, or visit the USP Web site at www.usp.org.
