| In a study involving adults living in North America with the metabolic syndrome (MetS) but without diabetes or cardiovascular disease, results indicate a high prevalence of low vitamin D levels in MetS patients. 30% of MetS patients showed vitamin D deficiency (less than 20 ng/mL) compared with only 8% of controls. Additionally, serum vitamin D levels were inversely correlated with fasting glucose levels and HOMA. Thus, the authors of this study conclude, "Future studies of vitamin D supplementation in these subjects on subsequent risk of diabetes will prove instructive with respect to potential health claims in these high risk patients with MetS." | Reference: | "Low Vitamin D levels in Northern American Adults with the Metabolic Syndrome," Devaraj S, Jialal I, et al, Horm Metab Res, 2010 Nov 25; [Epub ahead of print].
