Nature's Lab Gold Magnesium Glycinate 400 mg: 100 mg of magnesium per capsule, 4 capsules a day
100 mg of magnesium per capsule; the label's 4 capsules a day give 400 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.
Nature's Lab Gold Magnesium Glycinate 400 mg declares 400 mg of elemental magnesium per serving as glycinate, which needs 709–845 mg of magnesium glycinate 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; 17 of the 73 glycinate labels in this registry have a matched price. NIH DSLD 334722, label dated 2025-09-25.

Mass: 709–845 mg per capsule · Price: none matched · % DV: 95% vs 95%
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.

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.

Will 400 mg of glycinate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: Nature's Lab Gold Magnesium Glycinate 400 mg implies 709–845 mg of magnesium glycinate in each capsule to deliver 400 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.
computed with assumption| Measure | Value |
|---|---|
| Elemental magnesium per serving | 400 mg |
| Units per serving | 4 |
| Magnesium glycinate per serving | 2,837–3,381 mg |
| Magnesium glycinate per capsule | 709–845 mg |
| Capsule capacity 0 · 00 · 000 | 545 · 730 · 1,100 mg |
| Verdict | Needs size 00 |
The filed salt can have more than one hydration state (bisglycinate; chelate hydration varies by supplier), so the compound mass is a range.

How much elemental magnesium is actually in this label's filed magnesium lines?
Nature's Lab Gold Magnesium Glycinate 400 mg files 1 magnesium line in NIH DSLD 334722; the selected primary line declares 400 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 glycinate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, glycinate, 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%.
