Chemical Name of Vitamin D: Calciferol

Calciferol is the chemical name for vitamin D. It is a fat-soluble vitamin that plays a crucial role in maintaining overall health and well-being. Vitamin D exists in several forms, and calciferol specifically refers to two of its major forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol).

Vitamin D2 (Ergocalciferol)
- Ergocalciferol is derived from plant sources and is commonly found in fortified foods and supplements.
- It is synthesized by plants when they are exposed to sunlight and is then consumed by humans through dietary sources.
- Vitamin D2 is less potent than vitamin D3 and is primarily used in prescription medications for the treatment of vitamin D deficiency.

Vitamin D3 (Cholecalciferol)
- Cholecalciferol is the form of vitamin D that is synthesized in the skin when it is exposed to sunlight.
- It is also obtained through dietary sources such as fatty fish, egg yolks, and fortified dairy products.
- Vitamin D3 is considered the most effective form of vitamin D and is commonly used in over-the-counter supplements.

Importance of Vitamin D
- Vitamin D is essential for the absorption and utilization of calcium and phosphorus in the body, which are essential for maintaining healthy bones and teeth.
- It also plays a vital role in immune function, muscle function, and cell growth.
- Vitamin D deficiency can lead to conditions like rickets in children and osteomalacia in adults, which are characterized by weak and brittle bones.

Sources of Vitamin D
- Sunlight: The skin produces vitamin D when exposed to sunlight. However, factors like geographic location, season, and sunscreen use can affect the production of vitamin D in the skin.
- Dietary Sources: Vitamin D can be obtained from dietary sources such as fatty fish (salmon, mackerel, tuna), fortified dairy products (milk, yogurt), egg yolks, and fortified cereals.
- Supplements: In cases where dietary intake and sun exposure are insufficient, vitamin D supplements may be recommended.

In conclusion, the chemical name of vitamin D is calciferol, which encompasses both vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D is essential for maintaining healthy bones, teeth, and overall health. It can be obtained through sunlight exposure, dietary sources, and supplements.
