Calcium citrate malate
From Wikipedia, the free encyclopedia
Calcium citrate malate is a water-soluble calcium supplement. It is the calcium salt of citric acid and malic acid. It is found in products such as Citracal®, Tropicana Pure Premium® with calcium, and Propel Calcium fitness water (under the brand name Fruitcal®). 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.[1]
