Magnesium and calcium are fundamental nutrients that need to be in balance with each other in order for you to fully experience good health. Their importance on a cellular level is critical. Calcium and magnesium are like opposite sides of a coin. Calcium makes muscles contract. Magnesium is necessary for muscles to relax. Calcium excites nerves, while magnesium calms them down. Calcium is needed for blood clotting, but magnesium keeps the blood flowing freely. Magnesium helps your muscles and nerves function properly; it keeps your heart rhythm steady, supports a healthy immune system and also assists in keeping your bones strong. This essential mineral helps regulate blood sugar levels, promotes normal blood pressure and is required for producing and storing energy.
