Vitamin D deficiency (Q39932): Difference between revisions

Vitamin D is a fat-soluble vitamin contained naturally in very few foods, added to milk, available as a supplement, and produced endogenously with exposure to sunlight. Vitamin D deficiency can be caused by inadequate intake due to dietary factors (e.g., special diets (veganism), lactose intolerance or allergies) and/or limited exposure to sunlight due to geographic location, sun avoidance, or shiftwork. Severe deficiency results in disordered bone modelling called rickets in childhood (open growth plates), and osteomalacia in adults (fused growth plates).
