400 mg of magnesium per capsule, 1 a day. No US price matched (Nov 2). Inside: label lines, ingredients.

SNAP Magnesium Complex declares 400 mg of elemental magnesium per 1 vegetarian capsule(s); the magnesium salt is not resolved from the filed record, Single-salt capacity audit excluded as of 2026-10-17: buffered, complex, blend or asporotate wording leaves the composition unresolved., as of 2026-11-02. No US retail price matched as of 2026-11-02. NIH DSLD 332167, label dated 2025-06-25.

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.

Will 400 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 400 mg of magnesium per serving came from magnesium oxide (60.3% magnesium), the richest magnesium salt used in supplements, because the complex or buffer does not specify every carrier, the single capsule would need at least 663 mg of compound, so at this bound it needs at least a size 00 capsule (about 730 mg at 0.8 g/mL); the actual form, which the label does not name, may need more.

How much elemental magnesium is actually in this label's filed magnesium lines?

SNAP Magnesium Complex files 1 magnesium line in NIH DSLD 332167; the selected primary line declares 400 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.

What does "95% Daily Value" mean here, and does it recompute?

The label declares 95% Daily Value; 400 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 95%, the same within one point.

Why does this label contain magnesium stearate, what shell is it, and who is it filed for?

SNAP Magnesium Complex files 2 other ingredients, including magnesium stearate (reference fraction 4.1% magnesium; no quantity filed, so it is not added to the total) and a vegetarian shell.
