Vitamin World Magnesium Chloride 617 mg: 70 mg of magnesium per 1 caplet
70 mg of magnesium in each 1 caplet, about 0 servings per 90 Coated Caplet. Chloride is 12.0–25.5% magnesium. Inside: label lines, ingredients.
Vitamin World Magnesium Chloride 617 mg declares 70 mg of elemental magnesium per serving as chloride, which means 274–585 mg of magnesium chloride compound in one 1 caplet(s), compared with 1,100 mg in the largest standard capsule; capsule verdicts do not apply to this other (e.g. tea bag). 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 20965, label dated 2013-04-25.

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?
Vitamin World Magnesium Chloride 617 mg carries 274–585 mg of magnesium chloride per serving for 70 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this other (e.g. tea bag).

How much elemental magnesium is actually in this label's filed magnesium lines?
Vitamin World Magnesium Chloride 617 mg files 1 magnesium line in NIH DSLD 20965; the selected primary line declares 70 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 full NIH DSLD record text; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.
