KAL Magnesium Orotate 200: 50 mg of magnesium per capsule, 4 capsules a day
50 mg of magnesium per capsule; the label's 4 capsules a day give 200 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.
KAL Magnesium Orotate 200 declares 200 mg of elemental magnesium per serving as orotate, which needs 688 mg of magnesium orotate in each capsule, against 730 mg in a size 00 capsule at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range: it needs size 00 or larger. No US retail price matched as of 2026-11-02; 1 of the 4 orotate labels in this registry have a matched price. NIH DSLD 322919, label dated 2024-12-21.

Mass: 688 mg per capsule · Price: none matched · % DV: 48% 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.

Will 200 mg of orotate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: KAL Magnesium Orotate 200 implies 688 mg of magnesium orotate in each capsule to deliver 200 mg of elemental magnesium, against 1,100 mg in the largest standard capsule (size 000) at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range. Verdict: needs size 00, read at the most favourable hydration and the most units per serving.

How much elemental magnesium is actually in this label's filed magnesium lines?
KAL Magnesium Orotate 200 files 1 magnesium line in NIH DSLD 322919; 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 orotate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, orotate, resolved from the full NIH DSLD record text; at that salt the declaration is within the assumed size 000 capacity at powder density 0.8 g/mL, compared with oxide, the salt richest in magnesium at 60.3%.
