1.Vitamin D3 is a fat-soluble vitamin. Very few foods naturally contain this vitamin (fatty fish livers are an exception), and as a result, dermal synthesis is the major natural source of the vitamin.

2. Vitamin D3 is made by the body when skin is exposed to sunlight. Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D3 from the sun. Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D3 from the sun.

Vitamin D3 helps your body to absorb calcium and phosphorus. Having the right amount of vitamin D, calcium and phosphorus is important for building and retaining strong bones.

Vitamin D3 deficiency can be caused by unusually low sun exposure combined with lack of vitamin D-fortified foods or malabsorption. Alternatively, impaired hydroxylation of vitamin D in liver or kidney can prevent metabolism into the physiologically active form. Rarely, genetic defects may cause the end organs to be unresponsive to vitamin D, as in hereditary vitamin D-resistant rickets (HVDRR).

5. Vitamin D3 is used to treat and prevent bone disorders (such as rickets, osteomalacia). Also it prevents osteoporosis, falls, and fractures in the elderly population.
