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?
Genestra Brands Magnesium Complex Liquid Natural Tart Berry Flavor files 2 magnesium lines in NIH DSLD 211244; the selected primary line declares 500 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.

Does this label's magnesium claim hold up, or could the magnesium come from another source?
The label names 3 magnesium forms (citrate, glycinate, malate); a named blend does not establish how much magnesium each form contributes, so the resolved reading is the most favourable one, compared with oxide, the salt richest in magnesium at 60.3%.
computed with assumption| Form named on the label | Elemental fraction | Source |
|---|---|---|
| Magnesium citrate | 11.3–16.2% | named on label |
| Magnesium glycinate | 11.8–14.1% | named on label |
| Magnesium malate | 12.6–15.5% | named on label |

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, and without a resolved salt there is no same-salt comparison.

What does "60% Daily Value" mean here, and does it recompute?
The label declares 60% Daily Value; 500 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 119%, a difference of 59 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.
