Cholecalciferol is a form of Vitamin D and helps with the absorption of calcium in the stomach (7). Calcium is a vital part of dietary consumption in order to aid growth and maintenance of bones (1). Other important benefits of calcium include helping blood clotting (2), heart contractions (3), lungs (4) and muscles to function properly (5), this is due to calcium binding with phosphate to create calcium phosphate (6).
