Interpretive Summary:

Technical Abstract: In order to initiate the development of an analytically verified Dietary Supplement Ingredient Database (DSID), nationally representative samples of 35 adult multivitamin/mineral (MVM) products were selected to estimate content of 22 nutrients and to assess variability in products commonly reported as used in the U.S. These products represent over 55% of the most commonly reported adult products according to current national market-share data. The market-share data were verified using prevalence and frequency-of-intake from two previous national surveys. Samples (n=210) were obtained in six geographic locations from various market channels proportional to estimated use. Mass merchandisers were the most common channel (36% of purchases), followed by drug stores (17%), grocery stores (16%), warehouse stores (14%), and all others (17%). Samples were analyzed by a qualified commercial laboratory using validated QC methods. Analytical results obtained were statistically evaluated to determine nutrient ranges that may be used to estimate nutrient levels for similar MVM products that have not been sampled for analysis. Since nutrient intake from foods and supplements must be combined to evaluate impact of nutrient intake on health, information in the DSID will provide more accurate estimates of supplement intake than that from use of label databases.
