How much elemental magnesium is actually in this label's filed magnesium lines?
BulkSupplements.com Magnesium BHB Powder files 1 magnesium line in NIH DSLD 329631; the selected primary line declares 105 mg of elemental magnesium per serving, against 0 other rows excluded from the primary amount. A salt named under another nutrient does not turn that nutrient's quantity into elemental magnesium.

Does this label's magnesium claim hold up, or could the magnesium come from another source?
No single magnesium salt is resolved from the filed record as of 2026-11-02, so the source of the declared magnesium cannot be checked against capsule capacity, compared with oxide, the salt richest in magnesium at 60.3%.
