What are deficiency symptoms for vitamin D?
Vitamin D deficiency results in decreased absorption of calcium and phosphorus. As a result, prolonged vitamin D deficiency has a negative impact on bone mineralization. In infants and children, such a deficiency manifests itself as rickets, a condition characterized by bone deformities and growth retardation. Adults with vitamin D deficiency may experience bone pain and/or osteomalacia (soft bone). It is particularly important for individuals with limited sun exposure to include good sources of vitamin D in their diets. Homebound individuals, people living in northern latitudes, individuals who wear clothing that completely covers the body, and individuals working in occupations that prevent exposure to sunlight are at risk for vitamin D deficiency. In addition, breast milk may not contain a sufficient amount of vitamin D, so exclusively breast-fed infants may require supplemental vitamin D. What are toxicity symptoms for vitamin D? Excessive dietary intake of vitamin D can be toxic.
