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 ions are absorbed directly into intestinal cells, and the citrate complex enters the body through paracellular absorption.^{[citation needed]}

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.^[2]
