KAL Chelated Magnesium Bisglycinate: 105 mg of magnesium per tablet, 3–4 tablets a day
105 mg of magnesium per tablet; the label's 3–4 tablets a day give 315–420 mg. No US price matched (Nov 2). Inside: salt weight, %DV check.
KAL Chelated Magnesium Bisglycinate declares 315 mg of elemental magnesium per serving as glycinate, which means 2,234–2,663 mg of magnesium glycinate pressed into 3–4 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; 17 of the 73 glycinate labels in this registry have a matched price. NIH DSLD 322902, label dated 2024-12-21.

Mass: 559–666 mg per tablet · Price: none matched · % DV: 75% vs 75%
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 glycinate is pressed into one tablet?
KAL Chelated Magnesium Bisglycinate carries 2,234–2,663 mg of magnesium glycinate per serving for 315 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 | 315 mg |
| Units per serving | 3–4 |
| Magnesium glycinate per serving | 2,234–2,663 mg |
| Magnesium glycinate per tablet | 559–666 mg |

| Verdict | Capsule sizes do not apply |
The filed salt can have more than one hydration state (bisglycinate; chelate hydration varies by supplier), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
KAL Chelated Magnesium Bisglycinate files 1 magnesium line in NIH DSLD 322902; the selected primary line declares 315 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 glycinate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, glycinate, 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%.
