Welcome to the Dietary Supplement Ingredient Database (DSID) home page!
The Nutrient Data Laboratory (NDL), Beltsville Human Nutrition Research Center (BHNRC), part of the USDA Agricultural Research Service, working with the Office of Dietary Supplements, NIH, and other federal agencies, has developed a Dietary Supplement Ingredient Databases (DSID) to estimate levels of ingredients in dietary supplement products.
This first data release of the DSID (DSID-1) provides access to information on analyzed levels of nutrients in adult multivitamin/minerals (MVMs) used in the U.S. These estimates were derived from analytical data generated for a representative set of adult MVM products collected from various U.S. locations.
At this time, the DSID is intended primarily for research applications. For each of eighteen nutrients, product data were grouped by nutrient levels rather than by product names. Statistical regression analyses were used to estimate mean percent differences from label and variability at specific nutrient levels for each of the eight vitamins and ten minerals analyzed. These data are appropriate for conducting population studies of nutrient intake, rather than for assessing individual products.
The main features of DSID include data files, a research summary, and an adult MVM calculator. Regression equations are available for researchers with expertise to calculate multi-nutrient estimates of adult MVM supplement composition. A user-friendly calculator which uses the regression equations is also available as a research tool for those who want to obtain estimates of specific nutrient levels listed on the Supplement Facts labels of a limited number of adult MVMs. These estimates can be saved to build a small database for later use. Since over half of American adults report taking a dietary supplement, the estimates in the DSID will improve assessment of total nutrient intake from foods and supplements.
