At A Glance

Noteworthy Characteristics

  • The multivitamin/multimineral database is the first installment; analyses of single ingredient products, fish oil products and botanically based supplements are planned.
  • DSID data are intended primarily for research applications, such as population studies of nutrient intake at specific levels.
  • DSID-3 reports national analytically-derived estimates (not labeled values) for ingredient levels in a representative group of adult, children’s and non-prescription prenatal multivitamin/mineral (MVM) products and omega-3 fatty acid products.
  • DSID-4 was expanded to include botanical DS, with pilot study results for 32 green tea DS and data tables of constituent content. Also included was the second national study of adult MVMs, with estimates of ingredient content for vitamin A, vitamin D and chromium, new application tables and a new online calculator. A calculator function was added for the omega-3 fatty acid DS estimates, and additional DSID application tables were provided for non-prescription prenatal MVMs.



To provide levels of ingredients in dietary supplement products.

Target Population

Representative unspecified adult multivitamin/multimineral (MVM) supplements available in the United States (U.S.).


Project was initiated in 2004. Ongoing.


Agricultural Research Service, U.S. Department of Agriculture; Office of Dietary Supplements, National Institutes of Health, U.S. Department of Health and Human Services


Sample Design

Not a survey. The statistically-based sample in DSID-1 was designed to represent adult multivitamin/multimineral supplements used by the U.S. population, based on usage trends and market share data. DSID-3 also includes children’s and prenatal MVMs; calcium supplements; and products containing vitamin E, vitamin C and B-vitamins. DSID-4 includes content for vitamin A, vitamin D and chromium.
