Vitamin D is essential for the absorption and use of calcium and phosphorus, which are vital for functions such as the development of bones; healthy nervous and immune systems; regulation of some hormones and normal cell growth and maturation. Vitamin D is important for bone and muscle development, function, and preservation. Vitamin D is required to maintain normal blood levels of calcium and phosphate, which are in turn needed for the normal mineralisation of bone, muscle contraction, nerve conduction, and general cellular function in all cells of the body as well as bone growth and maintenance of bone density. May reduce the risk of falls, most likely due to improved muscle tone and strength. The requirement for vitamin D increases in pregnant women due to calcium deposition and bone mineralisation in the developing baby. D3 is the preferred form of vitamin D/ the form found in the human body. Vitamin D3 is the form found in the human body.

Cholecalciferol (vitamin D3) may be more effective at increasing serum 25-hydroxyvitamin D, a measure of vitamin D status, than ergocalciferol (vitamin D2). Vitamin D status is affected by the ageing process. Vitamin D is required throughout life. Those who rarely see daylight as they are always working indoors, or who always wear sun protection, may require additional dietary vitamin D. The people who can most benefit from supplementation are the elderly, those who avoid the sun, people with dark skin or who wear concealing clothing and people with reduced absorption of nutrients from the gut. The elderly may require additional dietary vitamin D, as the ability of the skin to make vitamin D with exposure to sunlight decreases with age. Older individuals may require a higher dietary intake of vitamin D to achieve vitamin D sufficiency, and to support normal calcium absorption and maintain healthy bones. In the absence of sun exposure, 1000 IU of cholecalciferol is needed to maintain healthy levels of vitamin D. The elderly may have an increased requirement for dietary vitamin D.
