Rising Mag64 Magnesium Chloride: 64 mg of magnesium per tablet, 2 tablets a day
64 mg of magnesium per tablet; the label's 2 tablets a day give 128 mg. No US price matched (Nov 2). Inside: salt weight, %DV check.
Rising Mag64 Magnesium Chloride declares 128 mg of elemental magnesium per serving as chloride, which means 501–1,070 mg of magnesium chloride pressed into 2 tablets, compared with 1,100 mg in the largest standard capsule; capsule verdicts do not apply to a tablet. 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 15759, label dated 2012-11-21.

Mass: 251–535 mg per tablet · Price: none matched · % DV: 32% vs 30%
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 is pressed into one tablet?
Rising Mag64 Magnesium Chloride carries 501–1,070 mg of magnesium chloride per serving for 128 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this tablet or pill.
computed with assumption| Measure | Value |
|---|---|
| Elemental magnesium per serving | 128 mg |
| Units per serving | 2 |
| Magnesium chloride per serving | 501–1,070 mg |
| Magnesium chloride per tablet | 251–535 mg |
| Capsule capacity 0 · 00 · 000 | 545 · 730 · 1,100 mg |
| Verdict | Capsule sizes do not apply |
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?
Rising Mag64 Magnesium Chloride files 1 magnesium line in NIH DSLD 15759; the selected primary line declares 128 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%.
