The active form of vitamin D, which is generated by chemical alterations in the liver and kidney. Calcitriol stimulates calcium absorption, bone formation and removal of calcium from bones.

The biologically active form of Vitamin D. Calcitriol"... enhances absorption of calcium and phosphorus from the intestine and may cause increased reabsorption of calcium in the kidneys. This serves to elevate the plasma concentrations of calcium and phosphorus and in a feedback loop with the parathyroid glands, prevents parathyroid hormone (PTH) from increasing osteoclastic action, which would lead to the release of calcium from the bones to the serum. Through these mechanisms, vitamin D sufficiency results in normal bone mineralization during development and growth in children and maintains bone strength in adults."
