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 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 |

| 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 files 1 magnesium line in NIH DSLD 179947; 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 filed magnesium line; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.

What does "63% Daily Value" mean here, and does it recompute?
The label declares 63% Daily Value; 250 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 60%, a difference of 3 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.
