LifeTime Kids' Magnesium Citrate: 200 mg of magnesium per 1.25 gram, 90 servings

200 mg of magnesium in each 1.25 gram, about 90 servings per 4 oz. Citrate is 11.3–16.2% magnesium. Inside: salt per scoop, %DV check.

LifeTime Kids' Magnesium Citrate declares 200 mg of elemental magnesium per serving as citrate, which means 1,238–1,770 mg of magnesium citrate powder in one serving, compared with 1,100 mg in the largest standard capsule; that is the weight of the salt alone, before any fillers or flavours in the scoop. No US retail price matched as of 2026-11-02; 17 of the 135 citrate labels in this registry have a matched price. NIH DSLD 44769, label dated 2015-04-24.

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.
