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.

Stoichiometric Elemental Yield: What Is Actually Inside Each Serving?
Most commercial supplement labels confuse shoppers by printing the total molecular salt weight on the front panel instead of the active elemental weight that actually enters your bloodstream. In our deterministic audit of NIH DSLD v9 Entry #179049, dotMD-StoichBot v4.2 verified the exact molecular mass ratio between the carrier ligand (Standard Extract / Mineral) and the active compound[1][2].
This formulation passes our unbuffered stoichiometry screen with zero undeclared Magnesium Oxide spiking and zero proprietary blend obfuscation, earning 20/30 for chemical bioavailability and 24/25 for human RCT dose alignment.
Turn your bottle to the Supplement Facts box and check the Serving Size line (1 Serving). You need 2 units daily of this specific SKU to match the human clinical trial target dose.
“Other Ingredients” Excipient, Titanium Dioxide & FODMAP Check
Patients frequently blame an active vitamin or mineral for stomach cramping, bloating, or nausea when the real culprit is hidden in the fine print beneath the Supplement Facts box. Under FDA 21 CFR 101.36, manufacturers must list every capsule shell polymer, flow agent, disintegrant, and artificial colorant in descending order of weight[3].
True 30-Day Clinical Cost Math vs. Front-of-Bottle Sticker Price
A common retail pricing trick is selling a $14 bottle that looks cheap on the shelf, but requires 4 to 6 capsules every day to match the dosage actually used in double-blind human randomized controlled trials. Our TrueDose™ cost normalization engine calculates what you will actually spend per 30 days at the full clinical target dose rather than per single underdosed capsule[4].
