Earth Vibes Magnesium Glycinate 275 mg: 92 mg of magnesium per capsule, 3 capsules a day
92 mg of magnesium per capsule; the label's 3 capsules a day give 275 mg. No US price matched (Nov 2). Inside: salt weight, capsule size.
Earth Vibes Magnesium Glycinate 275 mg declares 275 mg of elemental magnesium per serving as glycinate, which needs 650–775 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 322538, label dated 2025-01-23.

Mass: 650–775 mg per capsule · Price: none matched · % DV: 65% vs 65%
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 275 mg of glycinate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: Earth Vibes Magnesium Glycinate 275 mg implies 650–775 mg of magnesium glycinate in each capsule to deliver 275 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 | 275 mg |
| Units per serving | 3 |
| Magnesium glycinate per serving | 1,950–2,325 mg |
| Magnesium glycinate per capsule | 650–775 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?
Earth Vibes Magnesium Glycinate 275 mg files 1 magnesium line in NIH DSLD 322538; the selected primary line declares 275 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%.
