Freeda Magnesium Glycinate: 105 mg of magnesium per capsule, 2–4 capsules a day
105 mg of magnesium per capsule; the label's 2–4 capsules a day give 210–420 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.
Freeda Magnesium Glycinate declares 210 mg of elemental magnesium per serving as glycinate, which needs 372–444 mg of magnesium glycinate in each capsule, against 545 mg in a size 0 capsule at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range: it fits a size 0 capsule, the smallest of the three sizes compared here. 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 340043, label dated 2025-09-25.

Mass: 372–444 mg per capsule · Price: none matched · % DV: 50% vs 50%
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 210 mg of glycinate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: Freeda Magnesium Glycinate implies 372–444 mg of magnesium glycinate in each capsule to deliver 210 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: fits size 0, read at the most favourable hydration and the most units per serving.
computed with assumption| Measure | Value |
|---|---|
| Elemental magnesium per serving | 210 mg |
| Units per serving | 2–4 |
| Magnesium glycinate per serving | 1,489–1,775 mg |
| Magnesium glycinate per capsule | 372–444 mg |
| Capsule capacity 0 · 00 · 000 | 545 · 730 · 1,100 mg |
| Verdict | Fits size 0 |
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?
Freeda Magnesium Glycinate files 1 magnesium line in NIH DSLD 340043; the selected primary line declares 210 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%.
