In a 2004 study, subjects with low levels of vitamin D had almost 3 times the risk of metabolic syndrome. Thus, the researchers conclude that low vitamin D leads to insulin resistance and noted, "Now, we have one more reason to keep up vitamin D."1,2 This is supported by other research, where investigators noted, "Vitamin D deficiency may, therefore, be involved in the pathogenesis [cause] of both forms of diabetes.3" Vitamin D levels also tend to be low in diabetic children and vitamin D may even help to prevent the diabetes if given early.4
