Also known as 25-hydroxyvitamin D3, calcidiol, Calderol, U-32070E, (3beta,5Z,7E)-9,10-secocholesta-5,7,10(19)-triene-3,25-diol, (3S,5Z,7E)-9,10-secocholesta-5,7,10-triene-3,25-diol, (5Z,7E)-(3S)-9,10-secocholesta-5,7,10(19)-triene-3,25-diol, 25-hydroxycholecalciferol

Calcifediol, also known as calcidiol, 25-hydroxycholecalciferol, or 25-hydroxyvitamin D3 (abbreviated 25(OH)D3), is a form of vitamin D produced in the liver by hydroxylation of vitamin D3 (cholecalciferol) by the enzyme vitamin D 25-hydroxylase. Calcifediol can be further hydroxylated by the enzyme 25(OH)D-1α-hydroxylase, primarily in the kidney, to form calcitriol (1,25-(OH)2D3), which is the active hormonal form of vitamin D.

Calcifediol is strongly bound in blood by the vitamin D-binding protein. Measurement of serum calcifediol is the usual test performed to determine a person's vitamin D status, to show vitamin D deficiency or sufficiency. Calcifediol is available as an oral medication in some countries to supplement vitamin D status.
