Calcium citrate malate is a water-soluble calcium supplement. It is the calcium salt of citric acid and malic acid with variable composition. It is purported to be highly bioavailable.
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.
Calcium citrate malate is approximately (4-5%) more absorbable than calcium carbonate and is well absorbed regardless of stomach acid. Calcium is an essential mineral with a wide range of biological roles.
