New Chapter Magnesium + Ashwagandha: 325 mg of magnesium per tablet, 1 tablet a day, $11.99 a month
325 mg of magnesium per tablet; the label's 1 tablet a day cost $11.99 a month (Amazon, Nov 2). Inside: label lines, ingredients.
New Chapter Magnesium + Ashwagandha declares 325 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 $0.1229 per 100 mg, rank 4 of 17 ranked glycinate offers (1 = lowest price per 100 mg), percentile 24 (lower = lower price). NIH DSLD 253241, label dated 2021-08-23.

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?
New Chapter Magnesium + Ashwagandha files 1 magnesium line in NIH DSLD 253241; the selected primary line declares 325 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?
No single magnesium salt is resolved from the filed record as of 2026-11-02, so the source of the declared magnesium cannot be checked against capsule capacity, compared with oxide, the salt richest in magnesium at 60.3%.
