Elemental: The magnesium itself; the rest of the compound weight is the partner molecule.
Compound: The whole salt, such as magnesium glycinate, that must physically fit in the capsule.
Size 000: The largest standard capsule, about 1,100 mg of powder at 0.8 g/mL, the top of the usual 0.6–0.8 range; size 00 holds about 730 mg and size 0 about 545 mg.

How much elemental magnesium is actually in this label's filed magnesium lines?
CVS Pharmacy Natural Calcium, Magnesium & Zinc USP files 1 magnesium line in NIH DSLD 12010; the selected primary line declares 133 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%.
