Calcitriol plays a crucial role in the balance of which two minerals?

Calcitriol is the active form of vitamin D and is primarily involved in regulating the balance of calcium and phosphorus in the body. It promotes intestinal absorption of both minerals, ensuring that there is sufficient calcium for vital processes such as bone health and muscle function, as well as phosphorus which is crucial for energy production and bone structure.

Calcitriol helps to maintain appropriate levels of calcium in the bloodstream by facilitating its absorption from the diet and reducing renal excretion. It works in conjunction with parathyroid hormone (PTH) to achieve this balance. Similarly, phosphorus levels are regulated alongside calcium since they often influence one another, especially regarding bone metabolism.

Understanding the relationship between calcium, phosphorus, and the role of calcitriol is essential for healthcare providers because imbalances in these minerals can lead to serious health issues, particularly in patients undergoing hemodialysis, where mineral regulation can be significantly affected. Hence, the choice identifying calcium and phosphorus accurately highlights the critical function of calcitriol in mineral balance.
