One label reports compound and elemental figures per two capsules. The other reports elemental magnesium per one tablet. The comparison unit makes that distinction visible.
The cost figure compares 100 mg of stated elemental magnesium, regardless of whether the source reports it per one tablet, two capsules or powder weight.
Different formulas
Magnesium forms and other ingredients remain visible in each source record. Elemental cost alone does not assess the quality or effect of a formula.
