Magnesium improves prediabetes

Magnesium helps regulate blood sugar levels, and doctors wanted to test its effect in prediabetes, where blood sugar is elevated, but does not reach diabetic levels.

In this study, 116 men and non-pregnant women with low magnesium levels and a new diagnosis of prediabetes took a placebo or 97.5 mg of magnesium per day. After four months, fasting blood sugar levels declined 25 percent for those taking magnesium compared to 11 percent for placebo, bringing both groups into the normal blood sugar range. The magnesium group also had better glucose levels after a meal. Overall, half of those in the magnesium group improved their glucose status compared to 7 percent for placebo. Those taking magnesium also saw lower triglyceride levels and higher levels of HDL, the “good” cholesterol.
