Mass: 1,287–1,584 mg per tablet · Price: none matched · % DV: 95% vs 95%
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 malate is pressed into one tablet?
KAL Magnesium Malate 400 carries 2,574–3,167 mg of magnesium malate per serving for 400 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this tablet or pill.

| Elemental magnesium per serving | 400 mg |
| Units per serving | 2 |
| Magnesium malate per serving | 2,574–3,167 mg |

| Verdict | Capsule sizes do not apply |
The filed salt can have more than one hydration state (anhydrous 15.54% or dihydrate 12.63% (192.41 g/mol)), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
KAL Magnesium Malate 400 files 1 magnesium line in NIH DSLD 286789; the selected primary line declares 400 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 malate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, malate, 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%.
