Calcium citrate malate

Calcium citrate malate is a water-soluble calcium supplement. It is the calcium salt of citric acid and malic acid with variable composition.
Calcium citrate malate's bioavailability stems from its water-solubility and its method of dissolution. When dissolved, it releases calcium ions and a calcium citrate complex.
Calcium citrate malate is similar to calcium malate and other calcium salts. The European [Food Safety Authority] has concluded that calcium citrate malate is "slightly more bioavailable" than other forms of calcium supplementation.
