Magnesium<\/span><\/a> is an essential nutrient that is naturally found in some food sources and stored in the body\u2014primarily in the bones. However, some medicines and <\/span>magnesium supplements<\/span><\/a> also contain it. Though magnesium has many functions, it\u2019s mainly known for supporting nerve and muscle function, heart and bone health, mental health, and <\/span>blood sugar regulation<\/span><\/a>. Here, we break down the top evidence-based magnesium benefits, how to get enough of it, and when you should ask your provider about dietary supplements.<\/span><\/p>\n

8 health benefits of magnesium<\/span><\/h2>\n

Magnesium is involved in more than 300 enzymatic reactions in the body, says William Li, MD, medical director of the Angiogenesis Foundation and author of <\/span>Eat to Beat Disease<\/span><\/i>. Some of the key benefits of magnesium include its importance for strong bones, <\/span>heart health<\/span><\/a>, muscle function, and more.<\/span><\/p>\n

1. Supports organ function<\/span><\/h3>\n

Every organ in the body needs magnesium to function, especially the heart and kidneys, according to the National Library of Medicine. Magnesium is involved in hundreds of chemical reactions that keep your organs functioning, Dr. Li explains. For example, magnesium helps maintain a normal heart rhythm by regulating electrical impulses in the heart. There are 78 main organs in the human body, and each one is involved in essential functions, including some that your very survival depends on. Organ complications, such as heart failure from <\/span>heart disease<\/span><\/a>, can be life-threatening. So, it\u2019s important to provide organs with the nutrients they need to function, such as magnesium, to maintain good organ function and prevent health issues.<\/span><\/p>\n

2. Promotes bone health<\/span><\/h3>\n

There are a myriad of nutrients that are important for bone health, and magnesium is one of them, along with calcium, vitamin D, and others. In fact, magnesium works in concert with calcium and vitamin D to promote healthy bones, says <\/span>Patricia Bannan, RDN<\/span><\/a>, a registered dietitian nutritionist and the founder of Wellness Intelligence in Los Angeles. \u201cMagnesium helps activate vitamin D, which is essential for calcium absorption,\u201d Bannan explains. \u201cApproximately 60% of the body\u2019s magnesium is stored in our bones.\u201d The body then takes magnesium from the bones to keep blood levels stable, per the <\/span>National Library of Medicine<\/span><\/a>. If you are magnesium deficient, that could mean too much is used from your bones, weakening them.<\/span><\/p>\n

While strong bones are important for everyone, magnesium is especially important for older adults and those at risk for osteoporosis, Bannan says. She points to a <\/span>systematic review<\/span><\/a> that found a correlation between higher magnesium intake and increased bone mineral density.<\/span><\/p>\n

3. Regulates muscle function<\/span><\/h3>\n

Muscle mass helps you move around and contributes to a healthy metabolism. To keep your muscles healthy, you need to get enough magnesium. \u201cMagnesium plays a crucial role in muscle function, particularly in regulating muscle contractions,\u201d Bannan says, adding that this is especially relevant for athletes and individuals experiencing muscle cramps or spasms. If you\u2019ve ever used Epsom salts, which contain magnesium and other minerals, you may be familiar with magnesium\u2019s ability to soothe and relax <\/span>sore muscles<\/span><\/a>. These abilities even have research to back them up. Bannan points to a <\/span>\u00a0trial<\/span><\/a>, which found that magnesium supplementation can significantly reduce muscle soreness, promote recovery, and improve athletic performance.<\/span><\/p>\n

4. Maintains nerve function<\/span><\/h3>\n

The nervous system sends messages between the brain and various parts of the body, enabling you to think, move, and function. It\u2019s another bodily system that relies on magnesium to work properly, Bannan says. Specifically, magnesium regulates nerve signal transmission, she explains. When nerve cells are damaged, communication between the brain and body is affected, and symptoms like numbness, tingling, or pain may develop. Insufficient magnesium or excessive magnesium <\/span>has been linked<\/span><\/a> to peripheral neuropathy, though more research is needed. <\/span>Other research<\/span><\/a> has found that magnesium can promote nerve repair and regeneration.<\/span><\/p>\n

There may also be a link between magnesium levels and neurological disorders, such as <\/span>Alzheimer\u2019s disease<\/span><\/a>. However, more research is needed. <\/span>Research suggests<\/span><\/a> that magnesium may have protective effects against other neurological illnesses, including chronic pain, <\/span>migraines<\/span><\/a>, <\/span>stroke<\/span><\/a>, and <\/span>epilepsy<\/span><\/a>.<\/span><\/p>\n

5. Lowers blood pressure<\/span><\/h3>\n

The heart is an organ, but it\u2019s also a muscle, and as you know, magnesium plays an important role in muscle function. It can support heart health in several ways, including <\/span>lowering blood pressure<\/span><\/a>, <\/span>Dr. Li<\/span><\/a> says. Magnesium supplementation can significantly lower blood pressure in people with noncommunicable chronic diseases, according to a <\/span>\u00a0meta-analysis<\/span><\/a>.<\/span><\/p>\n

Magnesium helps maintain healthy blood pressure levels by allowing blood vessels to relax and dilate, Bannan explains. This can lead to a lower risk of hypertension. Healthy blood pressure levels can also lower the risk of cardiovascular diseases. Along with smoking and high cholesterol, high blood pressure is a key risk factor for heart disease, notes the <\/span>Centers for Disease Control and Prevention<\/span><\/a> (CDC).<\/span><\/p>\n
