Calcitriol role?

Calcitriol is the active form of vitamin D. Its main role is to raise the availability of calcium and phosphate for the body by increasing their absorption from the gut, which helps support bone mineralization and normal serum mineral levels. This is why describing calcitriol as activated vitamin D that increases calcium and phosphate best matches its function. The other statements don’t fit because calcitriol does not decrease gut calcium absorption, nor does it inhibit phosphate reabsorption; it generally promotes absorption of both minerals. While calcitriol can influence bone remodeling, it is not accurately described as simply reducing bone resorption.
