Natural Nutra Chelated Magnesium 250 mg: 250 mg of magnesium per tablet, 1–2 tablets a day – amino acid chelate + oxide
250 mg of magnesium per tablet; the label's 1–2 tablets a day give 250–500 mg. From amino acid chelate + oxide. Inside: label lines, ingredients.
Natural Nutra Chelated Magnesium 250 mg declares 250 mg of elemental magnesium from an amino acid chelate. "Amino acid chelate" names a class of compounds rather than one defined substance, so no elemental fraction exists and the compound mass cannot be computed from the label. No US retail price matched as of 2026-11-02. NIH DSLD 246886, label dated 2021-04-22.

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 elemental magnesium is actually in this label's filed magnesium lines?
Natural Nutra Chelated Magnesium 250 mg files 1 magnesium line in NIH DSLD 246886; 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 magnesium claim hold up, or could the magnesium come from another source?
The label names 2 magnesium forms (amino-acid-chelate, oxide); a named blend does not establish how much magnesium each form contributes, so the resolved reading is the most favourable one, compared with oxide, the salt richest in magnesium at 60.3%.
computed with assumption| Form named on the label | Elemental fraction | Source |
|---|---|---|
| amino-acid-chelate | No defined fraction | named on label |

Is this a good price for the elemental magnesium I'm actually getting?
No US retail price is matched to this label as of 2026-11-02, and without a resolved salt there is no same-salt comparison.

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.
