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 citrate compound is in one serving?
Country Life Magnesium Citrate + L-Theanine 400 mg Lavender Vanilla Flavor carries 2,475–3,540 mg of magnesium citrate per serving for 400 mg of elemental magnesium, against 1,100 mg in the largest standard capsule; capsule capacities do not apply to this liquid.
