Translations:D-Hormon/2/en

It has the function of a so-called prohormone in the body and is converted to the hormone calcitriol. Due to its formation and effect, vitamin D is considered to be similar to hormones. It plays an important role in the metabolism of the minerals calcium and phosphate, so it is extremely important for bone formation. Among other things, calcitriol promotes the absorption of calcium from the intestine and, together with the parathyroid gland, controls the level of calcium in the blood. In renal insufficiency less calcitriol is produced in the kidney and a calcium deficiency (hypocalcemia) develops.
