Solgar Chelated Magnesium: 100 mg of magnesium per tablet, 4 tablets a day, $11.07 a month – glycinate + oxide
100 mg of magnesium per tablet; the label's 4 tablets a day cost $11.07 a month (Amazon, Nov 2). From glycinate + oxide. Inside: label lines, ingredients.
Solgar Chelated Magnesium declares 400 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. Observed at $0.0923 per 100 mg, not ranked while its match is likely. NIH DSLD 217578, label dated 2020-04-23.

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.

How much elemental magnesium is actually in this label's filed magnesium lines?
Solgar Chelated Magnesium files 1 magnesium line in NIH DSLD 217578; the selected primary line declares 400 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, oxide); 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%.

| Formulation re: Other | Magnesium is a poly-active major essential mineral. Magnesium helps to regulate calcium transport and absorption. By stimulating the secretion of the hormone calcitonin, it aids the influx of calcium into bone and promotes optimal bone mineralization. Magnesium also works with ATP to release the energy needed to fuel most reactions in the body. It supports healthy nerve and muscle function. |
