Abstract

In the Dietary Supplement Ingredient Database (DSID), ingredients in dietary supplement (DS) products are chemically analyzed and the results statistically evaluated for nutritional applications. The first data release, DSID‐1, reported on 18 ingredients in adult multivitamin/mineral (MVM) products. Recently, children's MVMs were studied. Representative products were identified using National Health and Nutrition Examination Survey (NHANES) 2003–06 and current market data. Differences between adult and children's MVM products include product forms, nutrient ranges and total nutritional content. Adult MVMs reported in NHANES had median values of 12 vitamins and 7 minerals; children's MVMs had median values of 10 vitamins and 2 minerals. Multiple lots of >60 children's MVMs were purchased in 2008 using a nationwide sampling plan and analyzed with certified reference materials. Adult products showed a wider range of nutrient values than the children's. For 14 nutrients, the average range for adult MVMs was 2.7–4.5 times the average range for children's products. For 4 B vitamins (B12, B6, riboflavin, thiamin), the average range for adult MVMs was 40 times that of the children's MVMs. Preliminary analytical results for 18 nutrients in children's products, calculated as % difference from label, show some distinct differences when compared to adult MVM products.
