What Does Magnesium Do for the Human Body?

Magnesium helps keep the heart working normally and supports healthy blood pressure. It plays a role in the electrical signals that control the heartbeat and helps manage muscle function, including that of the heart. The mineral is also involved in processes that affect blood vessel function and the body's balance of other electrolytes. Getting enough magnesium is an important part of a heart-healthy diet. However, magnesium supplements should not be used instead of prescribed medications for blood pressure or heart conditions. Foods like beans, spinach, whole grains, and nuts can naturally provide magnesium and also offer other nutrients that support heart health.
