New Dietary Supplement Label Database

This summer a new Dietary Supplement Label Database (DSLD) was released to reflect information not only for the consumer, but for researchers, health care professionals, and students.

The goal of the new site is to capture dietary supplement information from nearly 50,000 labels. The initial release will have 17,000 – with 1,000 labels to be added monthly. In comparison, the old DSLD site contained information on over 8,000 products. The new DSLD is a partnership between the Office of Dietary Supplements (ODS) and the National Library of Medicine’s (NLM) Division of Specialized Information Services.

  3. Product For each dietary supplement product in the new site, the user can search the DSLD for all products with a specific brand and/or by the product names.
  4. Serving Size One serving of a dietary supplement equals the maximum amount recommended, as appropriate, on the label for consumption per eating occasion, or in the absence of recommendations, 1 unit (e.g., tablet, capsule, packet, teaspoonful, etc). If more than one serving size is listed, that information will be provided.
  5. Serving Size Unit A description of one serving’s form (e.g., tablet, capsule, ml).
  6. Dietary Ingredient “Ingredient” refers to the compounds used in the manufacture of a dietary supplement. For instance, when calcium carbonate is used to provide calcium, calcium carbonate is an “ingredient” and calcium is a “dietary ingredient.”
  7. Amount/Serving Size The names and the quantitative amounts by weight of each dietary ingredient.
  8. % DV Daily Value comprises two sets of dietary standards: Daily Reference Values (DRVs) and Reference Daily Intakes (RDIs). Only the percent Daily Value term appears on the label to make label reading less confusing and to help consumers see how a food fits into an overall daily diet.
  9. DV Target Group Refers to dosage information specific to certain populations such as adults, children, infants, etc.  For supplements, the assumed target is Adults and Children 4 or more years of age.
