This study looks at the relationship between calcium solubility and absorption, listing seven calcium sources.  Two of the sources used were Albion products: CCM (calcium citrate malate) and calcium bisglycinate chelate. The other calcium sources were three found naturally in foods and two other popular forms found commercially: calcium carbonate and calcium citrate.  This study is the result of 352 studies on human subjects and collated data from several years of absorption protocols.
