About


The Dietary Supplement Label Database (DSLD) includes full label derived information from dietary supplement products marketed in the U.S. with a Web-based user interface that provides ready access to label information. It was developed to serve the research community and as a resource for health care providers and the public. It can be an educational and research tool for students, academics, and other professionals.

Disclaimer: All information contained in the Dietary Supplement Label Database (DSLD) comes from product labels. Label information has not been verified or checked for conformity with existing U.S. Food and Drug Administration (FDA) regulations. The FDA enacted new labeling regulations in 2016, which fully take effect in 2020. During transition to the new regulations, some labels in the database may conform to the former, “old” regulations and others to the current, “new” regulations. Information on the “old” and “new” label formats can be found under the Help Menu tab. The presentation of dietary supplement label information is not an endorsement or guarantee of accuracy by the Office of Dietary Supplements or the National Library of Medicine, both part of the National Institutes of Health, U.S. Department of Health & Human Services.


The DSLD includes:

  • All information printed on dietary supplement product labels marketed in the United States;
  • Information capturing the name and form of active and inactive ingredients, amount(s) of active ingredient(s), percent daily value of nutrients, information about the manufacturer/distributor of products, label claims, warning statements, and a photograph of the entire label;
  • A historic component with label information for discontinued products;
  • Products reported by participants in recent National Health and Nutrition Examination Survey (NHANES);
  • User-selected calculators to:
    • assist in obtaining nutrient content using different units (e.g. IU or RE for Vitamin A);
    • determine an individual’s Dietary Reference Intake and compare it with labeled amounts;
  • Enhanced search options that enable users to locate specific terms on any aspect of a dietary supplement label using browse, search, and advanced search functions; and
  • An updated user interface designed to help users quickly find and sort information.

Note: The information in the DSLD reflects what manufacturers print on their labels. The information is not modified or corrected in any way.
