Mass: not computable · Price: none matched · % DV: 38% vs 37%
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.
Recompute with your price
Enter the price you paid; the declared amount and servings of this label are prefilled, so the result is the cost per 100 mg of elemental magnesium for your bottle.
Same-salt comparison appears here.
Will 155 mg of magnesium actually fit in one capsule, or do I need more than one?
The compound mass behind this label cannot be computed as of 2026-11-02: Single-salt capacity audit excluded as of 2026-10-17: one salt with a defined elemental fraction is not resolved.. The filed amounts are listed in the next block. Lower bound, not a measurement: even if all 155 mg of magnesium per serving came from magnesium oxide (60.3% magnesium), the richest of the 2 forms named for magnesium on the label, the single capsule would need at least 257 mg of compound, so at this bound it needs at least a size 0 capsule (about 545 mg at 0.8 g/mL); the actual mix of forms may need more.

How much elemental magnesium is actually in this label's filed magnesium lines?
New Sun Magnesium with Herbs files 1 magnesium line in NIH DSLD 203312; the selected primary line declares 155 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 (citrate, 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 |

| Magnesium citrate | 11.3–16.2% | 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.
