White or almost white crystals.

Calcifediol is a major circulating metabolite of vitamin D3 and acts as a competitive inhibitor with an apparent Ki of 3.9 μM. It is produced in the liver and is the best indicator of the body’s vitamin D stores. It is effective in the treatment of ricket

ChEBI: Calcifediol monohydrate is a vitamin D.

Calderol (Organon).

Cholecalciferol is an inactive form of vitamin D3 which undergoes various levels of hydroxylation to form active vitamin D3 analogs. 1α-Hydroxyvitamin D3 (alfacalcidol) is a synthetic analog that is metabolized to 1,25-dihydroxycholecalciferol, the biologically active form of vitamin D3. Other analogues of cholecalciferol result from different hydroxylations. 25-dihydroxycholecalciferol is a the major circulating form of vitamin D3 and a physiological precursor of 1α,25-Dihydroxycholecalciferol. The conversion is catalyzed by 25-Hydroxyvitamin D3 1-α-hydroxylase (VD3 1A hydroxylase) also known ascytochrome p450 27B1 (CYP27B1).

Calcidiol monohydrate contains the monohydrate form of the major circulating metabolite of vitamin D3 in the body and is a source of 1,25-dihydroxyvitamin D, the biologically active form of vitamin D. Calciferol monohydrate (25-hydroxycholecalciferol monohydrate) is safe under recommended conditions and level of use (up to 10 μg/day) and is safe for children >11 years of age and adults, including pregnant and lactating women.
