The Vitamin Shoppe Magnesium Citrate Complex 160 mg: 160 mg of magnesium per capsule, 1–2 capsules a day – citrate + oxide
160 mg of magnesium per capsule; the label's 1–2 capsules a day give 160–320 mg. From citrate + oxide. Inside: label lines, ingredients.
The Vitamin Shoppe Magnesium Citrate Complex 160 mg declares 160 mg of elemental magnesium per 1 capsule(s); the magnesium salt is not resolved from the filed record, servings per container are not filed, 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 54638, label dated 2015-12-23.

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 160 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 160 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 265 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?
The Vitamin Shoppe Magnesium Citrate Complex 160 mg files 1 magnesium line in NIH DSLD 54638; the selected primary line declares 160 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 |
| Magnesium oxide | 60.3% | 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.

What does "40% Daily Value" mean here, and does it recompute?
The label declares 40% Daily Value; 160 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 38%, a difference of 2 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.

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