Cholecalciferol is a form of vitamin D which is naturally synthesized in skin and functions as a pro-hormone, being converted to calcitriol. This is important for maintaining calcium levels and promoting bone health and development. [4] As a medication, cholecalciferol may be taken as a dietary supplement to prevent or to treat vitamin D ...
Calcium/cholecalciferol is a combination of a calcium salt and vitamin D 3 (cholecalciferol). It is used to prevent and treat lack of calcium and vitamin D in the elderly, as well for osteoporosis in combination with other medications. [1] [2]
Vitamin D is a group of structurally related, fat-soluble compounds responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, along with numerous other biological functions. [1] [2] In humans, the most important compounds within this group are vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol). [2] [3]
Vitamin D (the inactive version) is mainly from two forms: vitamin D 3 and vitamin D 2. Vitamin D 3, or cholecalciferol, is formed in the skin after exposure to sunlight or ultra violet radiation or from D 3 supplements or fortified food sources. Vitamin D 2, or ergocalciferol, is obtained from D 2 supplements or fortified food sources. [3]

Vitamin D deficiency or hypovitaminosis D is a vitamin D level that is below normal. It most commonly occurs in people when they have inadequate exposure to sunlight, ...
The natural, active form of vitamin D is calcitriol (1,25-dihydroxycholecalciferol). This molecule and other naturally occurring forms of vitamin D, including its precursors and metabolites, have been modified to synthesize pharmaceuticals with potentially greater, or selective, therapeutic actions.
Calcifediol is the precursor for calcitriol, the active form of vitamin D. [3] [4] It is synthesized in the liver, by hydroxylation of cholecalciferol (vitamin D 3) at the 25-position. [3] This enzymatic 25-hydroxylase reaction is mostly due to the actions of CYP2R1 , present in microsomes , although other enzymes such as mitochondrial CYP27A1 ...
