Vinco's Magnesium Glycinate: 300 mg of magnesium per serving
300 mg of magnesium per serving. Glycinate is 11.8–14.1% magnesium; no US price matched (Nov 2). Inside: salt per scoop, %DV check.
Vinco's Magnesium Glycinate declares 300 mg of elemental magnesium per serving as glycinate, which means 2,128–2,536 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 33919, label dated 2014-06-25.

Mass: 2,128–2,536 mg per serving · Price: none matched · % DV: 75% vs 71%
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 glycinate powder is in one scoop?
Vinco's Magnesium Glycinate carries 2,128–2,536 mg of magnesium glycinate per serving for 300 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this powder.

| Elemental magnesium per serving | 300 mg |
| Units per serving | Not a discrete unit as of 2026-11-02 |

| Verdict | Capsule sizes do not apply |
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?
Vinco's Magnesium Glycinate files 2 magnesium lines in NIH DSLD 33919; the selected primary line declares 300 mg of elemental magnesium per serving, against 1 other row excluded from the primary amount. A salt named under another nutrient does not turn that nutrient's quantity into elemental magnesium.

If 2,000 mg were the compound mass rather than the element, the elemental amount would be about 282 mg (14.1% of it), computed with a stated assumption.

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 filed magnesium line; capsule capacities do not apply to this form, compared with oxide, the salt richest in magnesium at 60.3%.

Is this a good price for the elemental magnesium I'm actually getting?
No US retail price is matched to this label as of 2026-11-02; 17 of 73 glycinate labels have one, against a median of $0.1889 per 100 mg among 17 ranked glycinate offers.

What does "75% Daily Value" mean here, and does it recompute?
The label declares 75% Daily Value; 300 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 71%, a difference of 4 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.
