Dietary Supplement Ingredient Database (DSID)

The Dietary Supplement Ingredient Database (DSID) will help researchers improve estimates of the U.S. population's total nutrient intakes. That's because the DSID was developed to improve estimates of the U.S population's nutrient intakes based not only on the beverages and foods people consume, but also on their dietary supplement intake.

The database provides statistical estimates—based on chemical analysis—of the nutrient content of selected ingredients in dietary supplements, compared with label-reported ingredient levels. Currently the DSID provides estimated levels of 18 vitamin and mineral ingredients derived from analytical data for 115 representative unspecified adult multivitamin/multimineral supplements (MVMs). Additional dietary supplement ingredients will be included in future releases of the database.

The DSID was planned and developed by the Agricultural Research Serviceexternal link disclaimer (ARS) Nutrient Data Laboratoryexternal link disclaimer at the Maryland-based Beltsville Human Nutrition Research Centerexternal link disclaimer and the National Institutes of Health Office of Dietary Supplements (ODS) and other government collaborators.
