Cholecalciferol works to help your body absorb calcium and phosphorus that are in the foods you consume. Once produced by your skin, consumed in your diet, or taken orally as a supplement, it is metabolized through two transformations in the human body to become active: In the Liver: The first of these transformations is from cholecalciferol into 25-hydroxyvitamin D (calcidiol), which happens to be the major circulating form of Vitamin D in your blood.

In the Kidneys: Here, calcidiol is converted into 1,25-dihydroxyvitamin D (calcitriol), which is the active form of Vitamin D. The active form is what ensures proper blood calcium, which leads to proper bone formation and maintenance.

Cholecalciferol maintains optimal levels of calcium and phosphorus, thus supporting bone mineralization, reduces the incidence of fractures, and enhances overall skeletal health. Furthermore, it also has anti-inflammatory and immuno-boosting features that help in the host body to combat infections and develops the body’s resistance against the chronic diseases.

While cholecalciferol is safe if one takes it with the prescribed quantities, an overdose may lead to side effects brought about by a condition known as hypercalcemia or high concentrations of calcium within the blood system.
