Vitamin D plays an important role in the body. It is needed for the absorption of calcium. Vitamin D produced in the skin and then converted in the liver and kidneys to its active form. Vitamin D deficiency can cause health problems such as muscle weakness, fractures, falls (in the elderly), and rickets.
Sun exposure is a natural trigger for Vitamin D production in the body. In colder climates where people do not get much sun exposure, Vitamin D supplementation may be necessary. Patients taking corticosteroids should also consider vitamin D supplementation.
The current recommendations for vitamin D according to the Institute of Medicine (IOM) is 600 to 800 IU per day (1.). Higher doses of vitamin D are used for treating known deficiencies. According to the IOM report the upper limit for supplementation is 4000 IU per day.
Vitamin D is found in foods such as fish and dairy products. Wheelock Pharmacy carries a variety of vitamin D supplements available in multiple vitamin preparations, vitamin D tablets or capsules, and liquids.
