What is magnesium?
Magnesium is an essential mineral for the human body, meaning the human body needs magnesium to be able to function properly.
Magnesium participates in the regulation of more than 300 biochemical processes in the bodyMagnesium: Fact Sheet for Health Professionals. It’s important for our heart health, our bones, our nervous system, glucose regulation, energy production, and many other processes.Magnesio en la dieta. It’s no surprise that magnesium also plays an important role in our ability to sleep.
Magnesium and sleep
Magnesium helps us sleep by:
- Restoring balance to our central nervous system
- Regulating the functioning of GABA neurotransmitters
- Assisting with the production of serotonin and, therefore, melatonin
Restoring balance to our central nervous system
Our central nervous system is divided into two parts: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PSNS).
The SNS is responsible for keeping us alert and active during the day. It’s also responsible for our fight-or-flight system and signals the release of stress hormones (cortisol) in the midst of danger. The PSNS, on the other hand, is responsible for all activities related to resting, digesting, and preparing the body for sleep Parasympathetic nervous system.
High stress in our daily lives can cause the SNS to become overactive and the PSNS to become underactive. This imbalance can lead to poor sleep.
Studies have shown that magnesium for sleep helps rebalance the two systems, reducing stress and anxiety and improving sleep problems Long-term HRV Analysis Shows Stress Reduction by Magnesium Intake.
Regulating the functioning of GABA neurotransmitters
Magnesium also helps regulate the functioning of our GABA neurotransmitters Magnesium Potentiation of the Function of Native and Recombinant GABA(A) Receptors, naturally occurring amino acids that play an important role in preparing the body to sleep.
GABA works as an inhibitory neurotransmitter. Its role is to block certain brain signals and decrease activity in the central nervous system to, ultimately, slow down the brain. Simply put, GABA’s job is to calm the mindMagnesium and Sleep. Magnesium helps GABA, and GABA helps us sleep.
Assisting with the production of serotonin
Serotonin, also known as the happy chemical, plays an important role in the production of melatonin, also known as the sleep hormone. Melatonin production is essential to be able to fall asleep quickly and to stay asleep throughout the night.
The production of serotonin and melatonin is dependent on the essential amino acid, tryptophan. When tryptophan metabolizes, it forms a compound called 5-HTP (5-Hydroxytryptophan). 5-HTP is necessary for the production of serotonin, which is necessary for the production of melatonin. L-tryptophan & 5-HTP (5-Hydroxytryptophan) Here’s a representation of the process:
Steps to create serotonin through tryptophan:
Tryptophan —► 5-Hydroxytryptophan (5-HTP) —► 5-Hydroxytryptamine —► Serotonin
Steps to create melatonin through tryptophan:
Tryptophan —► 5-Hydroxytryptophan (5-HTP) —► 5-Hydroxytryptamine —► Serotonin —► N-acetyl-serotonin —►Melatonin
Research supporting the role of magnesium for sleep
Several studies have found a clear relationship between magnesium deficiency and insomnia.
For example, in one study, scientists fed rats a magnesium-deficient diet and analyzed their sleep. They concluded that the rats stayed awake 50% longer than usual, that they suffered from neuronal excitability, and that the magnesium-deficiency significantly altered their sleep cycles. Specifically, their deep sleep was reduced by 24%Effects of a magnesium-deficient diet on sleep organization in rats.
Other studies show that magnesium helps us to fall asleep, have a deeper and more restful sleep, as well as avoid nighttime awakeningsThe magic of magnesiumThe effect of magnesium supplementation on primary insomnia in elderly: A double-blind placebo-controlled clinical trialThe effect of melatonin, magnesium, and zinc on primary insomnia in long-term care facility residents in Italy: a double-blind, placebo-controlled clinical trial.
It’s also been observed that people with anxiety and depression, factors that greatly affect the quality of sleep, have magnesium deficiencyMagnesium and depressionMagnesium supplementation improves indicators of low magnesium status and inflammatory stress in adults older than 51 years with poor quality sleep.
Since the body doesn’t produce magnesium on its own, it must be obtained from diet and/or supplementation. Foods highest in magnesium include green, leafy vegetables and nuts.
Unfortunately, epidemiological studies show that the general population consumes up to 30% less than the recommended daily dose of magnesiumMagnesio. Scientific Communication: Art o Technique?.
- Anyone with a low-vegetable diet
- Elderly people (especially women)

In addition, the following conditions make it difficult for the body to absorb proper amounts of magnesium and can, thus, lead to magnesium deficiencyMagnesium: Uses, Side Effects, Interactions, Dosage, and Warning:

Magnesium supplements for restless leg syndrome
Restless legs syndrome (RLS) is a condition caused by an alteration of the nervous system that’s characterized by an urgent need to move or touch the legs. People with this syndrome have trouble falling asleep and often wake up at night with the urge to walk around in order to relieve their symptomsRestless legs syndrome.
So far, there is no definitive cure for RLS. However, recent research indicates that magnesium supplementation may reduce symptoms.
In one study, 10 patients with RLS took a magnesium supplement for 4-6 weeks. The researchers concluded that magnesium supplementation was able to reduce their symptoms and improve their quality of sleepMagnesium therapy for periodic leg movements-related insomnia and restless legs syndrome: an open pilot study.

Magnesium Supplements - FAQ
Why are there so many kinds of magnesium supplements?
There are many kinds of magnesium supplements: magnesium carbonate, citrate, sulfate, magnesium oxide, chloride, threonate, malate, ascorbate, etc. This is because magnesium cannot be a molecule by itself. It has to bind to another element to be stable. Depending on the molecule that magnesium binds to, its level of absorption and its effects will be different.
Which magnesium supplement should I take for sleep?
The best way to choose a magnesium supplement for sleep is to look for a molecule that (a) enhances the relaxing effects of magnesium and/or (b) serves other functions that may be helpful to you.
Because glycine has a calming effect, magnesium glycinate is among the most recommended magnesium supplements for sleep.

Other natural sleep supplements
Melatonin (also known as the sleep hormone) is a hormone produced in the pineal gland of our brain that causes sleepiness and helps us synchronize our 24-hour sleep-wake cycle known as our circadian rhythm. Melatonin production is essential to be able to fall asleep quickly and to stay asleep throughout the night. If you have a hard time falling asleep and/or you find yourself waking up several times during the night, your body may be producing too little melatonin.

Tryptophan is an essential amino acid that our body needs to live and that we can only get from diet or supplementation. It serves to produce serotonin (the happiness hormone) which is necessary for the production of melatonin (the sleep hormone). That is, without tryptophan, your body cannot produce the serotonin or melatonin it needs to induce sleep.
Unfortunately, not everybody has adequate levels of tryptophan in their body. Poor nutrition, unhealthy habits, or medical conditions may lead to inadequate levels of tryptophan in the body.
