Most of us don’t get enough sleep. In today’s stressed out and super busy world, lack of sleep is one of the most common complaints. Beyond just not getting enough, around one-third of us every year suffer from full insomnia, which rises to 50% in people over 60 years of age (1). However, there may be a lack of one vital mineral in our bodies that’s the cause of this — magnesium. Even if you’re looking to sleep a little longer or a little more restfully, adding magnesium to your diet or through supplementation is something that can help you feel calm and relaxed, and improve your sleep. In this article, we are going to discuss which magnesium is best for sleep and to help you find out what causes magnesium deficiency.
How Can You Tell If You Have Magnesium Deficiency?
There are a few telltale signs to look for:
- Firstly you are having trouble going to sleep
- You are a light sleeper and wake up easily
- You are generally awake before your alarm
- You get regular cramps
- You need the toilet a lot after drinking fluids
- You have cold hands and feet
- You feel tightness in the neck and shoulders
- You are noticing twitches in the small muscles like the eyelids.
Any magnesium deficiency can also get worse with age as bad nutritional habits and the effects of stress built up and hit our gut function, causing gut absorption levels to go down.
Magnesium Is Best for Sleep, but How Does It Work?
Magnesium is vital for the proper functioning of GABA receptors in the brain and the central nervous system. GABA is the neurotransmitter that makes us relax, it’s the ‘chill pill’. Turning on the GABA receptors allows us to switch off and stop our racing minds. Magnesium also helps to reduce the stimulatory neurotransmitter glutamine, which promotes wakefulness and prevents us from sleeping. It also helps to deactivate and lower levels of cortisol and adrenaline the stress hormones (2,3).
Research in Medical Sciences Study on Magnesium and Sleeping
A study published in the Journal of Research in Medical Sciences on insomnia in the elderly during an eight-week trial in which the subjects were either given 500 mg of magnesium daily or a placebo, found that the group taking magnesium experienced a significant increase in sleep time and sleep quality. Also, reduction in the perceived effects of insomnia (the stress they felt from not sleeping), as well as reduction in cortisol and an increase in melatonin (a hormone that controls sleep and wake cycles) (4).
The authors concluded by saying that magnesium was an excellent treatment option in the elderly that should apply to the whole population. Given the results and the fact that magnesium is cheap and very safe to take, it seems an excellent option for anyone suffering from disturbed sleep. Try it and judge its effectiveness based on your own results!
How Long Does It Take for Magnesium to Work for Sleep?
Out of all the tricks, pills, and potions out there designed to help us get a better night’s sleep, magnesium is the most likely to make a difference within 24 hours. It’s utterly vital for making the systems that allow us to relax and go to sleep work. However, the problem is that 80% don’t get enough magnesium in our diets (5).
Nowadays, we have less magnesium in our water, salt, fruits, and vegetables. Our fruits and veggies grow more quickly, so they have less time to absorb magnesium from the soil (6). Also stress in itself leaches the body of magnesium, so that 80% of us are deficient is no surprise.
Which Magnesium Is Best for Insomnia?
Magnesium needs to be combined with another molecule to make it stable. That means there are many types available, for example, Magnesium citrate, ascorbate, or orotate. The different molecules magnesium is combined with actually changes the effectiveness of the magnesium, so choosing the right one is very important to get the maximum benefits available.
At Intelligent Labs, we’ve created the most effective magnesium for sleep that’s available. We have three different types of magnesium in our supplement, specifically chosen for their unique properties.
- Firstly we have Magnesium-L-Threonate. This scientifically advanced magnesium was developed by scientists at MIT to explicitly pass the blood-brain barrier, which is a protective barrier between the blood and the fluid of the brain. Most magnesium supplements cannot cross this barrier. However, Magnesium-L-Threonate does and can raise brain magnesium levels 2000% over ordinary magnesium supplements. This means more of the magnesium can work on the GABA receptors, and help to produce more melatonin directly aiding sleep
- Secondly, we use Magnesium Taurate. Taurate also acts directly on the GABA receptors as well as magnesium to bring further feelings of calm and better aid sleep.
- Finally, we use Magnesium Glycinate, the most absorbable form of magnesium for the bones and muscles (where most of the magnesium in the body is stored). This form is the most effective for reducing deficiencies outside the brain and means you can rest assured that your whole body will have enough magnesium so that it can be as healthy as possible.
