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?
AN Amazing Nutrition Amazing Formulas Magnesium Citrate 400 mg carries 2,475–3,540 mg of magnesium citrate per serving for 400 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this softgel capsule.
computed with assumption| Measure | Value |
|---|---|
| Elemental magnesium per serving | 400 mg |
| Units per serving | 3 |
| Magnesium citrate per serving | 2,475–3,540 mg |
| Magnesium citrate per softgel | 825–1,180 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.
