Wonder Labs Magnesium Glycinate: the label lists 98 mg, salt or magnesium?

The label lists 98 mg; if that is glycinate weight, it holds 12–14 mg of magnesium. No US price matched (Nov 2). Inside: salt weight, capsule size.

Wonder Labs Magnesium Glycinate declares magnesium without one determinable amount per 1–2 veg cap(s); Capacity audit excluded as of 2026-10-17: the filed amount may describe compound mass rather than elemental magnesium; the elemental amount is unresolved., as of 2026-11-02. 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 325862, label dated 2025-02-23.

Mass: not computable · Price: none matched · % DV: 23% vs n/a%

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.

Does the label's own text add up on magnesium?

The label's ingredient rows list 500 mg of magnesium glycinate and 98 mg of magnesium: 98 mg of magnesium from 500 mg of magnesium glycinate is 19.6% magnesium, against at most 14.1% that magnesium glycinate can carry. By the label's own numbers, at least 28% of the declared magnesium must come from a source other than the glycinate; this is computed from the label's words.

How much elemental magnesium is actually in this label's filed magnesium lines?

Wonder Labs Magnesium Glycinate files 2 magnesium lines in NIH DSLD 325862; 2 primary lines give no single elemental amount, 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%.

Why does this label contain magnesium stearate, what shell is it, and who is it filed for?

Wonder Labs Magnesium Glycinate files 3 other ingredients, including magnesium stearate (reference fraction 4.1% magnesium; no quantity filed, so it is not added to the total) and a vegetarian shell, against 28 of 73 glycinate labels that list magnesium stearate.
