Can Magnesium Help You Sleep Better?

Magnesium Help You Sleep Better

Magnesium is an essential mineral that plays a variety of important roles in the body, including regulating muscle and nerve function, blood pressure, and blood sugar levels. It is also involved in the production of melatonin, a hormone that helps to regulate sleep-wake cycles.

Several studies have shown that magnesium supplementation may help improve sleep quality in people with insomnia and other sleep disorders.  For example, a study published in the Journal of Sleep Medicine found that people who took magnesium supplements for 8 weeks reported improvements in sleep latency (the time it takes to fall asleep), sleep duration, and sleep quality.

Another study published in the Journal of Nutrition found that magnesium supplementation helped to reduce daytime sleepiness in people with chronic insomnia.

What is Magnesium?

Magnesium is an essential mineral that is found in the body's cells, bones, and tissues.It is involved in a variety of important bodily functions, including muscle contraction, nerve function, and blood pressure regulation.

Magnesium is also involved in the production of energy and the metabolism of carbohydrates, proteins, and fats. It is also important for the absorption of calcium and phosphorus, which are essential for bone health.

Magnesium deficiency can lead to a number of health problems, including muscle cramps, fatigue, and difficulty sleeping. It can also increase the risk of developing chronic diseases, such as heart disease and diabetes.

The recommended daily intake of magnesium for adults is 400-420 mg. Most people can get enough magnesium from their diet by eating a variety of foods, such as fruits, vegetables, nuts, and seeds. However, some people may need to take a magnesium supplement, especially if they have a magnesium deficiency.

Magnesium supplements are available in a variety of forms, including tablets, capsules, and powders. The best form of magnesium for you will depend on your individual needs.

Why is Magnesium Important for Sleep?

Magnesium is involved in the production of melatonin, a hormone that helps to regulate sleep-wake cycles.

Magnesium deficiency can lead to a number of health problems, including muscle cramps, fatigue, and difficulty sleeping. In fact, one study found that people with magnesium deficiency were more likely to have insomnia than people with normal magnesium levels.

The exact mechanism by which magnesium helps to improve sleep is not fully understood, but magnesium may help to relax muscles and nerves, which may make it easier to fall asleep. Magnesium may also help regulate melatonin levels, which may help improve sleep quality.

Benefits of Magnesium for Sleep

Let's delve deeper into the benefits of magnesium for sleep and how it can enhance overall sleep experiences:

Improves Sleep Quality:

Magnesium plays a role in maintaining healthy levels of GABA, a neurotransmitter that promotes sleep. Magnesium's ability to regulate neurotransmitters directly affects the nervous system and can lead to deeper, more restful sleep. By increasing the duration of slow-wave sleep, individuals may experience more significant physical and psychological restoration overnight, improving overall health and well-being.

Reduces Sleep Latency:

Quickening the transition from wakefulness to sleep, magnesium can be a boon for those who struggle to fall asleep. This mineral helps to quiet the nervous system and prepare the body for rest, making the onset of sleep smoother and potentially benefiting those suffering from insomnia.

Reduces Daytime Sleepiness:

By improving nighttime sleep quality, magnesium contributes to decreased daytime fatigue. Good sleep helps maintain the balance of sleep-wake cycles, known as circadian rhythms, which govern our alertness throughout the day.

Improves Mood:

Magnesium has a role in brain functions that regulate mood and stress response. By participating in the synthesis of serotonin, which later converts to melatonin (the sleep hormone), magnesium can impact our overall mood state and, by extension, influence sleep positively.

Reduces Anxiety:

Magnesium's soothing effect on the nervous system includes the reduction of neurological stress and anxiety. If anxiety levels drop, the body can relax more readily, setting the stage for a restful night without the alertness and agitation anxiety often induces.

Reduces Pain:

For individuals experiencing chronic pain, magnesium can be particularly valuable. It has a role in nerve function and muscle relaxation, which can help alleviate the conditions that often disturb or prevent sleep due to discomfort or pain.

Ask you, Doctors,

In supplementing with magnesium, it is crucial to follow recommended dosages and to consult with a healthcare provider, especially for those with medical conditions or those who are taking other medications, as magnesium can interact with various pharmaceuticals and has its own range of contraindications and side effects when taken in excess.

For specific recommendations on types of magnesium supplements and dosages, it would be best to consult with a healthcare professional who can provide guidance based on an individual's unique health status and needs.

How to Get Enough Magnesium

Dietary Sources of Magnesium:

Incorporating magnesium-rich foods into your daily diet is the most natural way to meet your magnesium needs. Here are some food groups and examples:

Leafy Green Vegetables:

  • Spinach

  • Swiss chard

  • Kale

  • Turnip greens

Nuts and Seeds:

  • Almonds

  • Cashews

  • Pumpkin seeds

  • Flaxseeds

  • Chia seeds


  • Black beans

  • Chickpeas

  • Lentils

  • Soybeans

Whole Grains:

  • Quinoa

  • Brown rice

  • Bulgur

  • Whole wheat bread

Additional Sources:

  • Avocado

  • Bananas

  • Dark Chocolate (at least 70% cocoa)

  • Fatty fish like salmon and mackerel

A balanced variety of these foods can help you reach the recommended daily allowance (RDA) for magnesium, which varies by age and gender.


While whole foods are the best source of magnesium, supplementation can be beneficial in certain circumstances:

Forms of Magnesium Supplements:

  • Magnesium Oxide: Often used for medicinal purposes, such as laxatives.

  • Magnesium Citrate: Known for its bioavailability and often used to improve digestion.

  • Magnesium Glycinate: Touted for its calming effects, may be beneficial for sleep and stress.

It's important to speak with a healthcare professional before starting any supplement regimen, as they can help you understand the right dosage and form for your specific needs.

Potential Side Effects of Magnesium:

While magnesium is vital for many bodily functions, too much of it can be harmful:

Digestive Issues:

Overuse of supplements can lead to diarrhea. High doses might cause stomach cramps or intestinal discomfort.

Electrolyte Imbalance: 

Excessive magnesium can disrupt the balance of other electrolytes, such as calcium and potassium. This can lead to symptoms like nausea or low blood pressure.

Kidney Stress:

Those with kidney issues must be cautious, as their kidneys may not remove excess magnesium effectively.

The recommended upper intake level for supplementary magnesium for adults is 350 mg per day, beyond which the risk of side effects increases.

Monitoring Your Intake:

If you're making dietary changes or adding supplements to ensure adequate magnesium intake, it might be beneficial to:

  • Keep a food diary to track your magnesium consumption.

  • Have periodic blood tests to monitor magnesium levels if you have a medical condition or are at risk of deficiency.

By following these guidelines and consulting with healthcare professionals, you can appropriately manage your magnesium intake and optimize your overall health.


Magnesium can be a helpful element in improving sleep quality and duration. It also has additional benefits for mood, anxiety, and pain. However, it's important to be careful with the amount of magnesium you consume, whether through your diet or supplements, as it can have side effects. It's best to consult with a healthcare professional before incorporating magnesium into your nocturnal routine. By doing so, you can achieve a more restful and rejuvenating night's sleep.
