Health benefits of magnesium
Magnesium is recognized for its wide range of potential health benefits and could be useful in the treatment of various conditions, from constipation to insomnia. Below are some of the main benefits of magnesium, according to experts.
It Can Help Manage Type 2 Diabetes
Magnesium deficiency significantly increases the risk of diabetes. Studies indicate that for each decrease of 100 milligrams per day in magnesium intake, the risk of diabetes increases by 15%. Magnesium supplementation can be beneficial for managing type 2 diabetes, since it could play a role in the regulation of insulin, the hormone responsible for transporting sugar from the bloodstream to the cells, helping to maintain healthy blood sugar levels. It has been observed that magnesium supplementation improves blood sugar in people with diabetes and also enhances insulin sensitivity, allowing the body to use insulin more efficiently.
It can help relieve constipation.
Some forms of magnesium have been used for a long time to relieve constipation and promote more regular bowel movements. Magnesium-based laxatives, such as magnesia milk or magnesium citrate, are commonly used to facilitate intestinal transit. They work by attracting water to the intestines, which helps to soften hard stools and facilitates their evacuation. Studies have found that magnesium oxide supplementation improves the frequency of bowel movements and the quality of life in people with chronic constipation.
It Could Improve Mental Health
Optimal magnesium is crucial for mental health. A magnesium deficiency can cause a variety of symptoms, including mild anxiety and nervousness. In addition, since magnesium participates in the regulation of the body’s stress response, it is believed that a deficiency could increase susceptibility to stress, which can contribute to depression. Low magnesium levels have also been associated with other conditions such as attention deficit hyperactivity disorder (ADHD) and autism. Research suggests that magnesium supplementation improves the symptoms of depression and generalized anxiety.
Could Assist in Sleep Regulation
It has been shown that magnesium levels are associated with the quality of sleep. Although it is not completely clear how it works, it is believed that magnesium deficiency could alter the sleep-vigil cycle, leading to symptoms of insomnia. Although more research is needed, “Association of magnesium intake with sleep duration and sleep quality” indicates the relationship between a higher magnesium intake with a better quality of sleep and a lower risk of short sleep duration.
Can Provide Relief of Migraines
Since magnesium participates in the maintenance of the health of the nervous system, a deficiency can cause neurological complications, including migraines. Research has linked an inadequate intake of magnesium with an increased risk of migraine headaches. “Magnesium acts as a N-methyl-D-aspartate (NMDA) receptor antagonist and blocks the NMDA receptor, resulting in its analgesic effect“, according to a review published in the National Library of Medicine.
It is shown that taking 400 to 500 milligrams of magnesium could reduce migraines. Supplementation with oral magnesium decreased both the frequency and intensity of migraine headaches.
It Could Support Heart
Health Magnesium can help protect heart health by reducing inflammation and maintaining the function of cell membranes. It could also improve heart health by reducing certain risk factors for heart disease, including blood pressure and blood sugar levels. Studies have associated a higher intake of magnesium with a reduced risk of several risk factors for heart disease.
It could help strengthen bones
Magnesium plays a key role in bone health; in fact, it is estimated that about 60% of the magnesium in the body is found in the bones. Magnesium can help increase bone density and reduce the risk of fractures. Reviews of studies have linked a higher magnesium intake with an increase in the general bone mineral density. Another study found that those with the lowest levels of magnesium in the blood had a three times higher risk of fracture compared to those with the highest levels.
Magnesium Citrate and Constipation
One of the primary reasons people turn to magnesium citrate is for relief from constipation. Its effectiveness in this regard is due to its osmotic properties, which draw water into the intestines, softening the stool and making it easier to pass. This can be particularly helpful for those suffering from occasional or chronic constipation.
When using magnesium citrate for constipation, it is essential to follow the dosage instructions carefully. Overuse can lead to diarrhea and electrolyte imbalances. Typically, a single dose is sufficient to produce a bowel movement within six hours. For chronic issues, it’s advisable to consult with a healthcare provider to ensure proper use and to rule out underlying conditions that might require different treatment.
