What does it do?

Cholecalciferol is a fat-soluble vitamin classified as vitamin D3. It is primarily used to promote the absorption of calcium and phosphorus to maintain bone health. In pharmaceuticals, it is included to prevent or treat vitamin D deficiency.

In the body, cholecalciferol is converted into active form vitamin D in the liver and kidneys, increasing the absorption of calcium and phosphorus in the intestines. This helps maintain blood calcium levels and supports bone formation and maintenance.

Questions about this ingredient

  • QIs it okay to take a separate Vitamin D product while on calcium supplements?

    Since calcium supplements or multivitamins may already contain vitamin D, taking them separately may lead to ingredient overlap. As cholecalciferol is fat-soluble, please compare the ingredients of the products you are taking, and consult a pharmacist to confirm whether they can be taken together.
