German researchers investigated the effect of oral magnesium supplementation on metabolic characteristics like insulin sensitivity (related to diabetes type 2) in non-diabetic patients with overweight. Subjects underwent a glucose test and were allocated to receive either a magnesium supplement (27 subjects) or a placebo (25 subjects) for 6 months. Several parameters were determined, like blood glucose and insulin levels. Magnesium supplementation significantly improved fasting blood glucose levels and some insulin parameters compared to the placebo. These results provide significant evidence that oral magnesium supplementation improves some diabetes-related parameters in diabetes patients, emphasizing that optimizing magnesium status may prevent type 2 diabetes. Further details can be found in the study.
