Magnesium is necessary to maintain the health of muscles. And the includes the the heart. Adequate magnesium intake has been associated with lower risks of:

  • atherosclerosis – fatty buildup on the walls of arteries
  • hypertension – high blood pressure

In a Framingham Heart Study, people who took the highest amounts of magnesium had a fifty eight percent lower chance of coronary artery calcification. They also a thirty four percent lower chance of abdominal artery calcification. Patients who receive magnesium right after a heart attack have a lower risk of death. Magnesium is sometimes used as part of the treatment for Congestive Heart Failure and reduces the risk of arrhythmia (abnormal heart rhythm). A daily intake of 365 mg of magnesium daily has been shown to improve lipid profiles. These are just a few of the benefits

The NIH notes “significant” higher magnesium levels in the blood with a lower risk of cardiovascular disease and of ischemic heart disease resulting from a low blood supply to the heart. They also note that higher magnesium levels may lower the risk of stroke. However, they point out that taking magnesium supplements lowers blood pressure “only a small extent.” The NIH calls for a large, well-designed investigation to understand how magnesium from the diet or from supplements might help protect the heart. More study is needed, but early indications are promising.
