Abstract:
National Institute of Standards and Technology (NIST), in collaboration with the National Institutes of Health-Office of Dietary Supplements and the U.S. Food and Drug Administration, is producing Standard Reference Materials (SRMs) for dietary supplements. These and other natural-matrix SRMs should be used in method validation, characterization of in-house quality control materials, and to establish traceability.
