dotMD.com uses `dotMD-StoichBot v4.2` and `dotMD-PharmAudit v4.2` to cross-audit every supplement guide against primary federal registries (`audit@dotmd.com`):

  • NIH ODS & DSLD v9 Stoichiometric Label Math: Compound-to-elemental weight ratios (such as `14.1%` elemental yield in anhydrous Magnesium Bisglycinate) and Tolerable Upper Intake Levels (UL) are verified against NIH Office of Dietary Supplements (ODS) and the NIH Dietary Supplement Label Database (DSLD v9) .
  • Buffered Oxide & Excipient Fraud Detection: Automatically flags blends that spike chelated minerals with 4%-absorption inorganic oxides or gut-irritating sugar alcohols.
  • Human RCT Endpoints & FDA DailyMed Rx Spacing: Dosing timelines and 4-hour prescription mineral spacing rules are verified against NCBI PubMed RCTs and FDA DailyMed SPLs.
