Zemvelo Magnesium: 100 mg of magnesium per 2.5 ml, 96 servings
100 mg of magnesium in each 2.5 ml, about 96 servings per 8.1 fl. Oz. Chloride is 12.0–25.5% magnesium. Inside: salt per scoop, %DV check.
Zemvelo Magnesium declares 100 mg of elemental magnesium per serving as chloride, which means 392–836 mg of magnesium chloride compound in one 2.5 ml (1/2 teaspoon), compared with 1,100 mg in the largest standard capsule; capsule verdicts do not apply to this liquid. No US retail price matched as of 2026-11-02; 0 of the 10 chloride labels in this registry have a matched price. NIH DSLD 229246, label dated 2020-06-24.

Mass: 392–836 mg per serving · Price: none matched · % DV: 25% vs 24%
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 chloride compound is in one serving?
Zemvelo Magnesium carries 392–836 mg of magnesium chloride per serving for 100 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this liquid.

The filed salt can have more than one hydration state (anhydrous 25.5%, hexahydrate 12.0%), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
Zemvelo Magnesium files 1 magnesium line in NIH DSLD 229246; the selected primary line declares 100 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 chloride claim hold up, or could the magnesium come from another source?
The label names one magnesium form, chloride, resolved from the filed magnesium line; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.
