PCOS Nutrition Center Magnesium Ultra Absorb: 150 mg of magnesium per capsule, 2 capsules a day
150 mg of magnesium per capsule; the label's 2 capsules a day give 300 mg. No US price matched (Nov 2). Inside: label lines, ingredients.
PCOS Nutrition Center Magnesium Ultra Absorb declares 300 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 331439, label dated 2025-05-21.

Mass: not computable · Price: none matched · % DV: 71% vs 71%
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.

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 300 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: buffered, complex, blend or asporotate wording leaves the composition unresolved.. The filed amounts are listed in the next block. Lower bound, not a measurement: even if all 300 mg of magnesium per serving came from magnesium oxide (60.3% magnesium), the richest magnesium salt used in supplements, because "buffered" on the label does not pin down the form, each of the 2 capsules would need at least 249 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?
PCOS Nutrition Center Magnesium Ultra Absorb files 1 magnesium line in NIH DSLD 331439; the selected primary line declares 300 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?
No single magnesium salt is resolved from the filed record as of 2026-11-02, so the source of the declared magnesium cannot be checked against capsule capacity, compared with oxide, the salt richest in magnesium at 60.3%.

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.
