Cholecalciferol is a fat-soluble secosteroid that plays a significant role in dietary supplements indicated for individuals suffering from vitamin D3 deficiency. It is an inactive form of vitamin D, which is converted into calcifediol in the liver and further converted into calcitriol in the kidneys. It helps in calcium intake in the body and cures bone-related disorders like rickets, osteomalacia, and osteoporosis. It also supports the absorption of phosphorus, which is essential for maintaining healthy bones and teeth.
Cholecalciferol undergoes enzymatic conversion in the body to show its biological effects. It is first converted to 25-hydroxyvitamin D in the liver, then further converted in the kidneys to its active form, calcitriol. After that, it binds to vitamin D receptors (VDRs), influencing gene expression, immune function, and bone metabolism.

Excessive intake of Vitamin D3 can lead to the accumulation of excess calcium in the blood, irregular kidney function, and cardiovascular problems.
Generally, Cholecalciferol is safe when used within the suggested guidelines of dietary and therapeutic doses.
Vitamin D3 helps to regulate keratinocyte differentiation and immune response in the scalp. It is frequently used as a supplement for the hair loss condition of telogen effluvium and alopecia areata.
Vitamin D is a fat-soluble secosteroid essential for calcium and phosphate regulation in the body, while Cholecalciferol is one of its forms, also called Vitamin D3, the natural form synthesized by the skin under sunlight and commonly used as a supplement.
Cholecalciferol is a fat-soluble secosteroid, a form of Vitamin D analog, and is classified as a prohormone that is converted to its active form, calcitriol, in the body.
Cholecalciferol (Vitamin D3) is generally more bioavailable and better retained than Vitamin D2 (ergocalciferol).
