Bluebonnet Magnesium Malate 425 mg: 142 mg of magnesium per capsule, 3 capsules a day
142 mg of magnesium per capsule; the label's 3 capsules a day give 425 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.
Bluebonnet Magnesium Malate 425 mg declares 425 mg of elemental magnesium per serving as malate, which needs 912–1,122 mg of magnesium malate in each capsule, 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: it fits only that size. No US retail price matched as of 2026-11-02; 2 of the 20 malate labels in this registry have a matched price. NIH DSLD 332604, label dated 2025-06-25.

Mass: 912–1,122 mg per capsule · Price: none matched · % DV: 101% vs 101%
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 425 mg of malate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: Bluebonnet Magnesium Malate 425 mg implies 912–1,122 mg of magnesium malate in each capsule to deliver 425 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 000, read at the most favourable hydration and the most units per serving.
computed with assumption| Measure | Value |
|---|---|
| Elemental magnesium per serving | 425 mg |
| Units per serving | 3 |
| Magnesium malate per serving | 2,735–3,365 mg |
| Magnesium malate per capsule | 912–1,122 mg |
| Capsule capacity 0 · 00 · 000 | 545 · 730 · 1,100 mg |
| Verdict | Needs size 000 |
The filed salt can have more than one hydration state (anhydrous 15.54% or dihydrate 12.63% (192.41 g/mol)), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
Bluebonnet Magnesium Malate 425 mg files 1 magnesium line in NIH DSLD 332604; the selected primary line declares 425 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 malate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, malate, 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%.
