ODS Reference Materials Search Tool

The National Institutes of Health (NIH) Office of Dietary Supplements (ODS) Reference Materials Search Tool (RMST) provides a platform to identify Reference Materials relevant to chemical analysis of dietary supplements, foods, and other natural products, including materials made available with support from the ODS Analytical Methods and Reference Materials Program.

Users can search for individual characteristics (e.g., specific botanicals or vitamins), as well as compare chemical constituents and composition across multiple related Reference Materials. The ODS website has a full listing of ODS AMRM-supported reference materials.
