### How Magnesium Affects Blood Sugar Levels in Diabetes Magnesium is a vital mineral that plays several important roles in your body, including managing insulin and carbohydrate metabolism. It helps your body secrete insulin and may improve how your cells use insulin. Research suggests that magnesium can help manage blood sugar levels in people with diabetes. Those who consume less magnesium often have poorer blood sugar control and a higher risk of type 2 diabetes. For instance, a review of 26 studies involving 1,168 people found that those with the highest magnesium intake had a 22% lower risk of developing type 2 diabetes compared to those with the lowest intake. Increasing magnesium intake through food or supplements may help people with diabetes improve their blood sugar regulation. A 12-week study involving 54 people with type 2 diabetes showed that taking 300 mg of magnesium daily significantly lowered fasting and post-meal blood sugar levels compared to a placebo. Similarly, a review of 18 studies found that taking 250–450 mg of magnesium daily for 6–24 weeks significantly reduced fasting blood sugar levels in people with diabetes or those at risk. In general, taking 250–350 mg of magnesium daily appears to benefit people with diabetes. It's best to take magnesium with food to improve absorption. However, if you have type 2 diabetes, consult your healthcare provider before taking magnesium, as it may increase the risk of hypoglycemia (low blood sugar) when combined with medication.
