Vitamins are compounds that you must have for growth and health. They are needed in small amounts only and are available in the foods that you eat. Vitamin D is necessary for strong bones and teeth. Lack of vitamin D may lead to a condition called rickets, especially in children, in which bones and teeth are weak. In adults it may cause a condition called osteomalacia, in which calcium is lost from bones so that they become weak. Your doctor may treat these problems by prescribing vitamin D for you. Vitamin D is also sometimes used to treat other diseases in which calcium is not used properly by the body. Ergocalciferol is the form of vitamin D used in vitamin supplements. Some conditions may increase your need for vitamin D. These include: Alcoholism Intestine diseases Kidney disease Liver disease OverActivity of the parathyroid glands with kidney failure Pancreas disease Surgical removal of stomach In addition, individuals and breast-fed infants who lack exposure to sunlight, as well as dark-skinned individuals, may be more likely to have a vitamin D deficiency. Increased need for vitamin D should be determined by your health care professional. Alfacalcidol, calcifediol, Gemcal-DS, and dihydrotachysterol are forms of vitamin D used to treat hypocalcemia (not enough calcium in the blood). Alfacalcidol, calcifediol, and Gemcal-DS are also used to treat certain types of bone disease that may occur with kidney disease in patients who are undergoing kidney dailysis. Claims that vitamin D is effective for treatment of arthritis and prevention of nearsightedness or nerve problems have not been proven. Some psoriasis patients may benefit from vitamin D supplements; however, controlled studies have not been performed
