Nutricost Magnesium Glycinate 210 mg: 210 mg of magnesium per 700 mg, 357 servings
210 mg of magnesium in each 700 mg, about 357 servings per 8.8 oz. Glycinate is 11.8–14.1% magnesium. Inside: salt per scoop, %DV check.
Nutricost Magnesium Glycinate 210 mg Unflavored declares 210 mg of elemental magnesium per serving as glycinate, which means 1,489–1,775 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 269725, label dated 2022-07-21.

Mass: 1,489–1,775 mg per serving · 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.

How much elemental magnesium is actually in this label's filed magnesium lines?
Nutricost Magnesium Glycinate 210 mg Unflavored files 1 magnesium line in NIH DSLD 269725; 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; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.
