The National Institutes of Health (NIH) Consensus …

Vitamin D metabolites enhance calcium absorption. 1,25-Dihydroxy vitamin D, the major metabolite, stimulates active transport of calcium in the small intestine and colon. Deficiency of 1,25-dihydroxy vitamin D, caused by inadequate dietary vitamin D, inadequate exposure to sunlight, impaired activation of vitamin D, or acquired resistance to vitamin D, results in reduced calcium absorption.

Elements in the Human Body and What They Do

Calcium Metal (Tomihahndorf) About 99% of the body’s calcium is found in bones and teeth, where the element is used to build strong structural compounds, such as hydroxyapatite. Although most of the calcium is in bones and teeth, this is not the mineral’s most important function.
