Magnesium Improves Insulin Sensitivity, Metabolic Control in Diabetes.
If I’m reading this right (and someone please correct me if I am!!) it looks like these patients got 2.5 grams of magnesium per day in this study. This is an incredible dose–which is good because too often we see clinical trials with supplements that use non-therapeutic levels and then say that it was of no benefit. Keep in mind that 2.5 grams would need to be administered carefully to avoid diarrhea (past a point where no more magnesium is absorbed, it stays in the colon and attracts water…).
