What Chronic Diseases Does Magnesium Prevent?

A new meta-analysis confirms that magnesium may help reduce the risk of developing seven chronic diseases linked to metabolic syndrome.

Magnesium is an essential mineral involved in more than 600 metabolic reactions in the human body. Now, a meta-analysis published in the journal Nutrients supports its protective role against metabolic syndrome, an increasingly common condition. This list summarizes the main chronic diseases that could be curbed with adequate magnesium intake, according to the most recent scientific evidence.

Type 2 diabetes

Several observational studies have found that magnesium plays a key role in regulating glucose and insulin sensitivity. Deficiency is linked to an increased risk of developing type 2 diabetes, a disease that affects millions of people worldwide. Maintaining adequate levels of this mineral can help prevent alterations in glucose metabolism.

Cardiovascular disease

Magnesium contributes to blood pressure control, improves lipid profiles, and has anti-inflammatory effects, all of which are key factors in preventing cardiovascular disease. Its protective effect on the vascular endothelium makes it an ally in caring for the heart and reducing events such as heart attacks and angina.

Non-alcoholic fatty liver disease

Fatty liver disease is directly associated with metabolic syndrome and often progresses without obvious symptoms. Recent studies suggest that magnesium may improve the liver’s insulin sensitivity and reduce fat accumulation in the liver, helping to prevent this condition before it leads to cirrhosis or chronic inflammation.

Chronic kidney disease

Kidney failure is closely linked to metabolic imbalances. Magnesium promotes improved kidney function by regulating glucose and blood pressure levels, factors that progressively deteriorate the kidneys. A diet rich in magnesium may delay or prevent the development of chronic kidney disease.

Stroke or cerebrovascular accident

Magnesium helps keep blood pressure under control and prevents blood clots from forming, which reduces the risk of stroke. The meta-analysis indicates that its positive effects on vascular health may translate into a lower incidence of serious neurological events such as stroke.

Polycystic ovary syndrome (PCOS)

In women, magnesium deficiency has been linked to the development of polycystic ovary syndrome, a hormonal disorder linked to insulin resistance, obesity, and metabolic disorders. Increasing magnesium intake could improve hormonal balance and reduce symptoms associated with PCOS.

Alzheimer’s dementia

Although its exact mechanisms are still being investigated, magnesium may play a neuroprotective role. Some studies observe a lower incidence of cognitive decline in people with adequate levels of this mineral, suggesting that it may delay the onset of neurodegenerative diseases such as Alzheimer’s.
