NusaPure Magnesium Oxide 1000 mg: the label lists 1,000 mg, salt or magnesium?
The label lists 1,000 mg; if that is oxide weight, it holds 603 mg of magnesium. No US price matched (Nov 2). Inside: salt weight, capsule size.
NusaPure Magnesium Oxide 1000 mg was observed at $19.35 on 2026-09-21; a cost per 100 mg of elemental magnesium is not computed for it because the filed elemental amount (1000 mg per serving) is likely the compound mass. The observation stays visible and enters no ranking. NIH DSLD 274963, label dated 2022-11-22.

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.
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.

Will the declared mg of oxide 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: Capacity audit excluded as of 2026-10-17: the filed amount may describe compound mass rather than elemental magnesium; the elemental amount is unresolved.. The filed amounts are listed in the next block. No lower bound: Capacity audit excluded as of 2026-10-17: the filed amount may describe compound mass rather than elemental magnesium; the elemental amount is unresolved..

How much elemental magnesium is actually in this label's filed magnesium lines?
NusaPure Magnesium Oxide 1000 mg files 1 magnesium line in NIH DSLD 274963; the selected primary line declares no single elemental amount, 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 oxide claim hold up, or could the magnesium come from another source?
The label names one magnesium form, oxide, 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%.

Is this a good price for the elemental magnesium I'm actually getting?
NusaPure Magnesium Oxide 1000 mg was observed at $19.35 on 2026-09-21, but no cost per 100 mg is computed because the filed elemental amount (1000 mg per serving) is likely the compound mass; against 5 ranked oxide offers with a median of $0.0293.
