Woodstock Vitamins Easy Magnesium: 125 mg of magnesium per capsule, 2–4 capsules a day – glycinate + lysinate
125 mg of magnesium per capsule; the label's 2–4 capsules a day give 250–500 mg. From glycinate + lysinate. Inside: label lines, ingredients.
Woodstock Vitamins Easy Magnesium declares 250 mg of elemental magnesium from an amino acid chelate. "Amino acid chelate" names a class of compounds rather than one defined substance, so no elemental fraction exists and the compound mass cannot be computed from the label. No US retail price matched as of 2026-11-02. NIH DSLD 326357, label dated 2025-01-23.

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.

Same-salt comparison appears here.
Will 250 mg of magnesium actually fit in one capsule, or do I need more than one?
The compound mass behind this label cannot be computed as of 2026-11-02: Single-salt capacity audit excluded as of 2026-10-17: buffered, complex, blend or asporotate wording leaves the composition unresolved.. The filed amounts are listed in the next block. Lower bound, not a measurement: even if all 250 mg of magnesium per serving came from magnesium oxide (60.3% magnesium), the richest magnesium salt used in supplements, because the complex or buffer does not specify every carrier, each of the 2 capsules (the most the serving allows) would need at least 207 mg of compound, so at this bound it needs at least a size 0 capsule (about 545 mg at 0.8 g/mL); the actual form, which the label does not name, may need more.

How much elemental magnesium is actually in this label's filed magnesium lines?
Woodstock Vitamins Easy Magnesium files 1 magnesium line in NIH DSLD 326357; the selected primary line declares 250 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 magnesium claim hold up, or could the magnesium come from another source?
The label names 2 magnesium forms (glycinate, lysinate); 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 glycinate | 11.8–14.1% | 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 "63% Daily Value" mean here, and does it recompute?
The label declares 63% Daily Value; 250 mg against the 420 mg reference in 21 CFR 101.9 recomputes to 60%, a difference of 3 points. Labels filed under the earlier 400 mg reference, or with a different filing basis, show gaps of this kind.

| Formula re: Contains | Magnesium, the fourth most abundant mineral in the human body, plays a role in over 300 metabolic processes. It participates in the development and maintenance of bones and teeth; the metabolism of carbohydrates, blood glucose, fats, and proteins; the formation of cells and tissues; and the maintenance of muscle function, including cardiac muscle. Easy Magnesium contains Albion's TRAACS magnesium lysinate glycinate (mineral amino acid chelate) and Albion's chelated dimagnesium malate-both formulated for enhanced absorption. Malic acid (from di-magnesium malate) supports energy production and lactic acid clearance via the Krebs cycle. Malic acid may also support antioxidant systems by enhancing glutathione and antioxidant anzymes. |
