1) Vitamin D helps to improve the body's sensitivity to insulin, by Regulation of IR gene – the hormone responsible for regulating blood sugar levels – and thus reduce the risk of insulin resistance, which is often a precursor to type 2 diabetes. Ideally, your blood level of 25 OH D should be 60ng/ml. 2) Low levels of vitamin D are a prevalent issue in people with and without diabetes across the globe. Research has repeatedly found a clear association between low vitamin D levels in patients with insulin resistance and a high risk of developing type 2 diabetes, as shown in this 2011 study from Canada.
In type 1 diabetes, the body produces antibodies that attack cells in the pancreas. This means the pancreas can't produce insulin, a hormone that controls blood sugar. In general, higher vitamin D levels were linked with a lower risk of producing antibodies and therefore a lower risk of…
