Nutra BioGenesis Tri-Magnesium: 100 mg of magnesium per capsule, 1–4 capsules a day (salt not resolved)
100 mg of magnesium per capsule; the label's 1–4 capsules a day give 100–400 mg. Salt not resolved from the NIH record. Inside: label lines, ingredients.
Nutra BioGenesis Tri-Magnesium declares 100 mg of elemental magnesium per 1 capsule(s); the magnesium salt is not resolved from the filed record, Single-salt capacity audit excluded as of 2026-10-17: one salt with a defined elemental fraction is not resolved., as of 2026-11-02. No US retail price matched as of 2026-11-02. NIH DSLD 323014, label dated 2024-12-21.

Mass: not computable · Price: none matched · % DV: 24% vs 24%
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 100 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 100 mg of magnesium per serving came from magnesium oxide (60.3% magnesium), the richest magnesium salt used in supplements, because the label names no form, the single capsule would need at least 166 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 form, which the label does not name, may need more.

How much elemental magnesium is actually in this label's filed magnesium lines?
Nutra BioGenesis Tri-Magnesium files 1 magnesium line in NIH DSLD 323014; the selected primary line declares 100 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 "24% Daily Value" mean here, and does it recompute?
The label declares 24% Daily Value; 100 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 24%, the same within one point.
