California Academy of Health Calm Magnesium Caps: 400 mg of magnesium per capsule, 2 capsules a day (salt not resolved)

400 mg of magnesium per capsule; the label's 2 capsules a day give 800 mg. Salt not resolved from the NIH record. Inside: label lines, ingredients.

California Academy of Health Calm Magnesium Caps declares 800 mg of elemental magnesium per 2 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 314707, label dated 2024-07-25.

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 800 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 800 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, each of the 2 capsules 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?

California Academy of Health Calm Magnesium Caps files 1 magnesium line in NIH DSLD 314707; the selected primary line declares 800 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 "200% Daily Value" mean here, and does it recompute?

The label declares 200% Daily Value; 800 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 190%, a difference of 10 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.
