Kala Health Magnesium Complex: 200 mg of magnesium per capsule, 1–2 capsules a day
200 mg of magnesium per capsule; the label's 1–2 capsules a day give 200–400 mg. No US price matched (Nov 2). Inside: label lines, ingredients.
Kala Health Magnesium Complex declares 200 mg of elemental magnesium per 1–2 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 311314, label dated 2024-07-25.

Mass: not computable · Price: none matched · % DV: 53% vs 48%
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.

Same-salt comparison appears here.
Will 200 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 200 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, each of the 2 capsules (the most the serving allows) 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?
Kala Health Magnesium Complex files 1 magnesium line in NIH DSLD 311314; the selected primary line declares 200 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 "53% Daily Value" mean here, and does it recompute?
The label declares 53% Daily Value; 200 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 48%, a difference of 5 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.

| Formula re: Contains | This extraordinary formula contains magnesium from seawater concentrate, with magnesium in the correct proportion to the more than 70 other minerals and trace elements that are naturally present in seawater. This is important, because many minerals influence each other in terms of absorption and excretion. Both the magnesium and the other minerals in this natural formula form ions in the stomach, and as such are easily absorbed. This makes this formula superior to other magnesium-only formulas. |
| Suggested/Recommended/Usage/Directions | Recommended dosage: Adults take 1-2 capsules daily, or as recommended. Best taken with meals. Do not exceed the recommended dosage. |
