INS and Insulin resistance: Magnesium deficiencies in type 2 DM have been shown in several studies,8-11 and a low magnesium level can impair glucose homeostasis and insulin sensitivity in these patients.8,12 On the other hand, the Hisayama study has shown that magnesium intake decreases type 2 diabetes risk through the improvement of insulin resistance and inflammation.13 Complications of DM develop when tissues are chronically exposed to high blood glucose levels.
