  The present invention provides a calcium absorption enhancer that places no burden on the body of a human or a domestic animal to which a calcium compound is administered and can increase the efficiency with which a calcium content is absorbed into the body by supplying calcium ions in the stomach or the like of the human or the domestic animal in a sustained-release manner after administration of the calcium compound. The calcium absorption enhancer of the present invention contains, as an active ingredient, water-soluble calcium particles that can release calcium ions in an aqueous solution in a sustained-release manner.
