What does it do?

Concentrated cholecalciferol is a type of vitamin D3, primarily used to regulate calcium and phosphorus metabolism. It is included in medications to promote calcium absorption and support bone health. It is prescribed to improve vitamin D deficiency or calcium insufficiency.

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

Approved uses differ by product. Check each product's information for its actual use.
