Technical Abstract: Accurate nutrient data for dietary supplement composition are essential for determining supplements’ contribution to total dietary intake. To plan a nationwide adult multivitamin/mineral (MVM) study, the USDA Nutrient Data Laboratory (NDL) obtained prevalence information for the most common labeled levels and ranges of Se, Cr, Vitamin D, and other priority nutrients for adult MVM products, using National Health and Nutrition Examination Survey (NHANES) data. This information was used as the basis for developing a sampling plan that would include representative adult MVM products at specific nutrient levels to provide a range of data for conducting regression analysis. This year, a preliminary data release of adult MVM composition information will be available for researcher use to evaluate diet and health interrelationships in the U.S. population. The Office of Dietary Supplements and NDL have been collaborating on this work. The publicly available database at NDL, the Dietary Supplement Ingredient Database (DSID), will complement the nutrient database for foods known as the USDA National Nutrient Database for Standard Reference. The DSID will ultimately permit more accurate estimates of total nutrient intake to include both food and supplements and will permit the assessment of variability among and within supplement products.
