Magnesium is an essential mineral that plays a huge role in making your body system function optimally. Without magnesium, your nerves won’t send and receive messages; your muscles won’t work the way they’re supposed to. In fact, magnesium is needed for more than 300 chemical reactions in the body. Unfortunately, your body cannot produce or make magnesium on its own. What this means is that your body depends on the food you eat for magnesium. Although you can get magnesium from multivitamins and supplements, it’s best to get this mineral from natural foods. Besides, taking magnesium supplements can be dangerous if you have certain conditions, such as kidney failure, heart block, bowel obstruction, heart block, and myasthenia gravis. The best way to keep healthy levels of magnesium in your body is to eat foods that are high in this mineral.
