Nootropics Depot Magnesium Glycinate: 200 mg of magnesium per 1600 mg, 156 servings
200 mg of magnesium in each 1600 mg, about 156 servings per 8.8 Ounce. Glycinate is 11.8–14.1% magnesium. Inside: salt per scoop, %DV check.
Nootropics Depot Magnesium Glycinate declares 200 mg of elemental magnesium per serving as glycinate, which means 1,418–1,691 mg of magnesium glycinate powder in one serving, compared with 1,100 mg in the largest standard capsule; that is the weight of the salt alone, before any fillers or flavours in the scoop. 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 232373, label dated 2020-08-23.

Mass: 1,418–1,691 mg per serving · Price: none matched · % DV: 50% 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.

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?
Nootropics Depot Magnesium Glycinate files 1 magnesium line in NIH DSLD 232373; 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 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; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.
