Elemental: The magnesium itself; the rest of the compound weight is the partner molecule.
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.
Estimated salt mass versus assumed capsule capacity
0 of 1 audited capsule label are above the assumed size 000 capacity at powder density 0.8 g/mL, against 8 of 137 across the registry. 1 fit size 0 or 00 and 0 need size 000, at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range and the most favourable hydration.
