Magnesium’s like a quiet sidekick for people with diabetes—it helps your body use insulin more effectively, which means better blood sugar control. Low magnesium levels can make it harder for your cells to absorb sugar from the blood, leading to spikes. It also plays a role in keeping nerves and muscles working smoothly, supports heart health, and can even help reduce inflammation. Since some diabetes medications and high blood sugar can deplete magnesium, getting enough through foods like nuts, leafy greens, and fatty fish can make a real difference. Think of it as small mineral, big impact.
