What the Label Data Shows

Mega-Mag 400 mg is cataloged in the NIH Dietary Supplement Label Database (DSLD) as a mineral supplement built from 6 ingredients from Trace Minerals Research, sold in liquid form. A single-ingredient-group formula like this keeps the label's dosing simple to read.

Across a broader 6-ingredient formula, 6 of 6 carry no FDA reference-intake value, typical for a formula this size: larger blends tend to pull in botanicals, amino acids, and specialty compounds without an assigned Daily Value. Breadth like this isn't a red flag by itself.

A product's market status is worth checking before relying on this label. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2014-08-26. Off-market products are no longer being produced or distributed under this label, but the DSLD preserves their historical label data for researchers, consumers checking older bottles, and for tracking how formulations have evolved.
