Approved Science Magnesium Complex: the label lists 200 mg, salt or magnesium?
30 servings filed for this label. Salt not resolved from the NIH record; no US price matched (Nov 2). Inside: label lines, ingredients.
Approved Science Magnesium Complex declares magnesium without one determinable amount per 1 capsule(s); the magnesium salt is not resolved from the filed record, Capacity audit excluded as of 2026-10-17: the filed amount may describe compound mass rather than elemental magnesium; the elemental amount is unresolved., as of 2026-11-02. No US retail price matched as of 2026-11-02. NIH DSLD 319784, label dated 2024-11-22.

Mass: not computable · Price: none matched · % DV: 48% vs n/a%
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 the declared 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: 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?
Approved Science Magnesium Complex files 1 magnesium line in NIH DSLD 319784; 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 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.
