About

The mention of specific products and brands at this site does not constitute or imply a recommendation or endorsement by the National Library of Medicine.

This database contains information on the ingredients of over 2,000 brands of dietary supplements sold in the U.S. and is designed to help not only researchers, but the large audience of supplement consumers as well. While consumer-oriented information about dietary supplements is available from many sources, this database consolidates and centralizes the information that consumers require to make informed decisions about supplements and provides direct links to pertinent health information, fact sheets, research findings and on-going clinical studies at the National Institutes of Health (NIH)

The database is designed to help answer the following typical questions:

What are the ingredients shown on labels of specific brands?
Which brands claim to contain specific chemical ingredients?
What fraction of daily recommended nutrients is provided by a specific brand?
Can I compare the amount of a specific nutrient between brands?
What are inactive ingredients in each brand?
Which brands do not contain animal products?
Can I find studies that indicate the proven medical benefits of specific ingredients?
Can I find information on the toxicity of specific ingredients?
Who manufactures a specific brand? How do I contact this manufacturer?
What other information is available about chemicals in the toxicology-related databases of the National Library of Medicine?

Information in the Dietary Supplements Labels Database (the database) is from a variety of publicly available sources including brand-specific labels and information from manufacturers' web sites. We do not test products nor do we investigate to determine if this information is complete or accurate. We do our best to record the information as it appears on labels and other sources. Manufacturers frequently change formulations and although we strive to keep information current, a lag period may occur between when a manufacturer makes a change to a label and the change appears in the database. As a result, we cannot guarantee that the information in the database is 100% accurate, current or complete at a particular point in time. When precise ingredient information is important, the database is not a substitute for reading the labels on products you use or for contacting the manufacturer, for which purpose we have provided telephone numbers and mailing addresses.

Initial funding for this database was provided by the National Center for Environmental Health of the Centers for Disease Control and Prevention (CDC). Brands shown in the database were first selected in 2005 based on market share and shelf presence in retail stores such as drugstores, supermarkets and natural vitamin stores. The latest additions to the database include brands sold at on-line stores and by practitioners and the sample was modified to incorporate the types of supplements and brands used by populations surveyed during CDC's latest National Health and Nutrition Examination Survey (NHANES).
