Vitamin D is a fat-soluble vitamin that is essential for absorbing enough calcium and phosphorus for the body. It is needed for bone growth, mineralization and remodeling. According to the Office of Dietary Supplements, a vitamin D deficiency causes the bones to become brittle, thin and misshapen. Vitamin D also plays an important role in maintaining healthy immune and neuromuscular function in the body, and a deficiency can cause symptoms of fatigue and depression.
