Improvements to regression analyses for DSID national estimates of ingredient content have been made since the release of DSID-4 data in 2017. Two main updates were made to DSID-4 data: (1) adjusted definitions of multivitamin/minerals (MVMs), which affected the number of supplements included in analyses, and (2) incorporation of revised market share weighting into regression analyses.
The ‘change files’ provided below are intended for researchers who used DSID-4 data in previous analyses and who wish to update their results to more accurately estimate micronutrient intakes from MVMs and omega-3 supplements.
The fourth release of the Dietary Supplement Ingredient Database (DSID-4) reports national estimates for ingredient levels in dietary supplements (DS), based on chemical analysis. In addition pilot study results for green tea DS are reported. A brief description of each file is listed below with individual links to the data files. Combined data files that include all tables are available for download in MS Excel 2007 and Access 2007 formats. Individual files are available for download in MS Excel 2007 and SAS formats.
