Vitamin D deficiency in children has been linked to adverse effects, such as growth failure and rickets. Although vitamin D is available in several foods and drinks, recent estimates suggest the prevalence of vitamin D deficiency among children is between 12% and 24%. Family physicians should understand current recommendations for vitamin D supplementation and be prepared to educate parents about sun precautions and nutrition throughout childhood. Adequate levels of vitamin D may also help reduce the risk of autoimmune conditions, infection, and type 2 diabetes. Evidence from observational studies supports the role of vitamin D supplementation in reducing the risk of type 1 diabetes in children.
