Vitamin D deficiency predisposes individuals to type 1 and type 2 diabetes, and receptors for its activated form-1α,25-dihydroxyvitamin D 3 have been identified in both beta cells and immune cells. Vitamin D deficiency may, therefore, be involved in the pathogenesis of both forms of diabetes, and a better understanding of the mechanisms involved could lead to the development of preventive strategies. [1],[2] Although the role of vitamin D in helping to regulate blood glucose remains poorly understood, vitamin D status appears to play a role in the development and treatment of diabetes. It is possible that optimal levels of serum vitamin D may be different for people at risk for developing diabetes, those with diabetes, and those without diabetes. Both animal and human studies support the notion that adequate vitamin D supplementation may decrease the incidence of type 1 and possibly also of type 2 diabetes mellitus and may improve the metabolic control in the diabetes state. However, the exact mechanisms are not clear and need further investigation. [3],[4] Another study finding support a mechanistic link between serum vitamin D concentrations, glucose homeostasis, and the evolution of diabetes in a large segment of adult population, and it recommends screening people with elevated A1C levels for vitamin D insufficiency should be considered. [5] So, further experts' opinion and clinical evidence-based medicine need to be discussed more about these debatable important clinical issues, especially regarding vitamin D deficiency among diabetic patients.
