Mass: 1,418–1,691 mg per tablet · Price: none matched · % DV: 48% vs 48%

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.
