Nature Made Magnesium Citrate 250 mg: 125 mg of magnesium per softgel, 2 softgels a day
125 mg of magnesium per softgel; the label's 2 softgels a day give 250 mg. Softgel fill is not modelled (Oct 17). Inside: label lines, ingredients.
Nature Made Magnesium Citrate 250 mg declares 250 mg of elemental magnesium per serving as citrate, which means 1,547–2,212 mg of magnesium citrate compound in one 2 softgel(s), compared with 1,100 mg in the largest standard capsule; capsule verdicts do not apply to this softgel capsule. No US retail price matched as of 2026-11-02; 17 of the 135 citrate labels in this registry have a matched price. NIH DSLD 279878, label dated 2022-12-13.

Mass: 774–1,106 mg per softgel · Price: none matched · % DV: 60% vs 60%
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 citrate compound is in one serving?
Nature Made Magnesium Citrate 250 mg carries 1,547–2,212 mg of magnesium citrate per serving for 250 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this softgel capsule.

|---|---|
| Elemental magnesium per serving | 250 mg |
| Units per serving | 2 |
| Magnesium citrate per serving | 1,547–2,212 mg |
| Magnesium citrate per softgel | 774–1,106 mg |

| Verdict | Capsule sizes do not apply |
The filed salt can have more than one hydration state (trimagnesium dicitrate 16.2%; dibasic and hydrated forms as low as 11.3%), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
Nature Made Magnesium Citrate 250 mg files 1 magnesium line in NIH DSLD 279878; the selected primary line declares 250 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 citrate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, citrate, 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%.
