Magnesium is important for maintaining a healthy heartbeat. It naturally competes with calcium, which is essential for generating heart contractions. When calcium enters your heart muscle cells, it stimulates the muscle fibers to contract. Magnesium counters this effect, helping these cells relax.
Calcium and magnesium are minerals that are both important for bone density and have opposite effects on nerve, muscle and clotting activity. Calcium stimulates and magnesium relaxes or decreases activity.
Magnesium may improve bone health both directly and indirectly, as it helps to regulate calcium and vitamin D levels, which are two other nutrients vital for bone health.
Magnesium is needed for more than 300 biochemical reactions in the body. It helps to maintain normal nerve and muscle function, supports a healthy immune system, keeps the heartbeat steady, and helps bones remain strong. It also helps adjust blood glucose levels. It aids in the production of energy and protein.
The body needs calcium to maintain strong bones and to carry out many important functions. Almost all calcium is stored in bones and teeth, where it supports their structure and hardness. The body also needs calcium for muscles to move and for nerves to carry messages between the brain and every body part.
