Your doctor may prescribe magnesium for muscle pain, which can be a symptom of magnesium deficiency. Magnesium, a mineral, is essential to many functions in the body, including the metabolism, the physical and chemical processes in the body that convert and use energy.
Magnesium Benefits
镁对身体的许多功能至关重要，包括转换和使用能量的身体中的物理和化学过程。身体中的每个器官，尤其是心脏，肌肉和肾脏，需要镁。
Magnesium also contributes to the makeup of teeth and bones. An adult body contains approximately 25 grams magnesium, with 50 to 60 percent being present in the bones, and most of the rest in the soft tissues, according to theNational Institutes of Health.
Magnesium naturally occurs in many foods, including fruits and vegetables. It can be added to other food products, is available as a dietary supplement, and is present in some medicines (such as antacids and laxatives).
A September 2015 article in the journal营养素注意到，许多营养专家认为，镁的理想摄入量应基于体重（例如，每公斤4至6毫克，每天4至6毫克）。一般每日推荐剂量通常被列为400毫克。

A magnesium or potassium deficiency of in your diet can also cause muscle pain, with dehydration exacerbating the issue, aHarvard UniversityHealth Letterexplains.
As the article in营养素揭示，镁对调节肌肉收缩，血压，胰岛素代谢，心脏兴奋性，血管传神，神经传递和神经肌肉传导至关重要。镁中的不平衡通常涉及低镁或低镁血症，可能导致不必要的神经肌肉，心脏或神经障碍。
If you are experiencing muscle pain and you suspect it is caused by a lack of magnesium, speak to your doctor. Magnesium deficiency is diagnosed through a blood test, and your doctor may prescribe magnesium supplements if it presents. It may take six months to see results, as magnesium levels are slow to return to normal.
If you prefer not to take supplements but want toadd magnesium to your bodyfrom non-food sources, you can rub oil of magnesium, or magnesium chloride, onto your skin. Or you can take anepsom盐, or magnesium sulfate, bath to ease muscle pain.

来自一个人的饮食的镁通常不是健康风险，因为肾脏消除了尿液中的过量镁。联邦政府的2015-2020 Dietary Guidelines for Americansadvises that nutritional needs, including valuable minerals and vitamins, should come primarily from food sources.
If you take magnesium supplements, ingesting high doses of magnesium can havesome side effectssuch asdiarrhea with nausea和abdominal cramping. Magnesium-containing laxatives and antacids, when taken in large doses — more than 5,000 mg of magnesium a day — have been associated with magnesium toxicity. These symptoms include hypotension, nausea, vomiting, facial flushing, retention of urine, depression and lethargy, before progressing to muscle weakness, difficulty breathing, extreme hypotension, irregular heartbeat and cardiac arrest.
In addition, some medications may not be compatible with magnesium supplements, especially oral bisphosphonates for osteoarthritis and many antibiotics. It's best to speak with your doctor before you take any supplements, especially if you're taking medication.
