A good night’s sleep can be the difference between a productive day and feeling like you’re in a fog. Energy aside, sleep is when your body repairs itself.
Failing to get enough high-quality sleep can hold you back physically just as much as it does mentally. While melatonin and pharmaceutical sleep solutions might work, they leave you feeling groggy. That’s why magnesium is the best addition to your bedtime routine.
Our Insomnia Ending soak fights the type of stress that keeps you up at night. It lulls your body and mind into a relaxed state so you can reduce wandering thoughts and drift away to dreamland. But how long does it take for magnesium to work for sleep?
We get asked this question all the time. The short answer is, it depends. You’ll probably feel your mind shutting down and your body easing into complete relaxation by the time you get out of the tub if you use our magnesium bath soak.
There are quite a few other factors to consider regarding how long for magnesium to work for sleep, though. The type of magnesium, how you take it, dosage and timing, age, stress levels, and more all play a part.
We’ll help you set your expectations below and show you how you can improve both the efficiency and effectiveness of magnesium for sleep. But if you haven’t already, take the first step by getting the best stress relief bath soak at Flewd Stresscare today!
The Link Between Magnesium and Sleep
Magnesium plays a role in more than 300 biochemical processes in the body. It regulates muscle and nerve function, supports heart rhythm, aids in blood sugar control, and contributes to bone strength. But, it’s link to sleep quality is underappreciated.
Magnesium helps activate the parasympathetic nervous system, the branch responsible for calming the body and preparing it for rest. It also plays a key role in regulating melatonin, the hormone that controls your sleep-wake cycle.
The mineral binds to GABA (gamma-aminobutyric acid) receptors in the brain. This neurotransmitter slows brain activity and promotes relaxation, both of which are necessary to fall and stay asleep.
Low magnesium levels have been linked to sleep difficulties. You might feel as if you have trouble falling asleep when you’re deficient in magnesium - or you may just wake up throughout the night. You might fall asleep and stay asleep, but fail to get into the deep, restorative sleep state you need to actually wake up refreshed.
People dealing with chronic stress, physical tension, or nighttime restlessness can turn to magnesium to reset the system and create the right conditions for deeper, more restorative sleep.
You don’t want to wait around to notice a difference, though. How long does it take for magnesium to work for sleep?
How Long Does it Take for Magnesium to Work for Sleep?
Ultimately, how long for magnesium to work for sleep comes down to how it’s delivered. Oral supplements like magnesium glycinate or citrate typically take several hours to absorb. But even then, you won’t feel anything noticeable for several weeks of consistent use.
Transdermal forms, on the other hand, bypass the digestive system and enter the bloodstream through the skin. Magnesium chloride soaks, lotions, or sprays get to work right away. You might feel your muscles relaxing within 30-60 minutes.
Be clear, magnesium is not a sedative. It’s not going to knock you out cold like melatonin or pharmaceutical sleep solutions might. What it does is create the ideal conditions for deep, restful sleep. It deactivates a racing mind and eases a tense, stressed body.
Even with transdermal application, though, meaningful changes in sleep duration, fewer night-wakings, or more restful mornings take time. You need to be consistent and patient. Yet, you want to sleep better now - and you just might. But the best is yet to come!
So, how long does it take for magnesium to work for sleep? Although many of our customers feel the magnesium bath soak benefits after the very first use, we still encourage you to wait 5-10 days for the real results.
Factors Influencing How Long For Magnesium to Work for Sleep
Let’s take a closer look at some of the moving pieces impacting how long for magnesium to work for sleep. This will help you better set your expectations - and it will also show you what you can do to speed things up a bit.
The Type of Magnesium Supplement You Choose
Not all magnesium supplements offer the same impact on sleep. Magnesium oxide, for example, is poorly absorbed and often used for constipation, not neurological support.
Magnesium glycinate is better suited for relaxation due to its glycine component, but it still falls short in a few key areas. So, which magnesium is best for sleep? Magnesium chloride. It’s by far the most bioavailable, which means your body can more easily absorb and use the mineral.
Choosing the wrong type for your sleep needs can delay or reduce the benefits entirely. But aside from magnesium form, supplement type matters as well.
Oral vs Transdermal Absorption
There are two broad types of magnesium supplements, and we’ve talked about both throughout this guide so far: topical magnesium vs oral supplements.
Most people are drawn towards oral supplements, be it powder or capsules, because they’re so convenient, cheap, and readily available. The problem is your body can’t absorb these supplements very well. Most of what you take is going to go to waste.
Worse, oral magnesium supplementation is linked to frustrating, uncomfortable side effects like bloating, gas, and diarrhea. These things are just going to keep you up at night rather than help you sleep better!
That’s the beauty of topical application. You won’t have to deal with any of these uncomfortable side effects because you can bypass the digestive system altogether.
Magnesium soaks in particular are great because you get the mineral evenly distributed throughout your entire body. These types of products work almost immediately, too.
Dosage, Timing, and Consistency of Use
Magnesium needs to be taken consistently to support long-term sleep. You won’t notice much of a difference if you’re not taking it regularly or in high enough doses.
This can be a double edged sword, though. Because oral magnesium supplements have such low bioavailability, you’d think the answer is taking a higher dose. The problem is you may just find yourself dealing with more of those digestive problems we mentioned.
Timing also matters. Using magnesium too early is going to reduce its ability to support nighttime relaxation. A therapeutic dose in the evening helps reinforce your body’s natural sleep signals.
Age, Stress Levels, and Nutrient Status
Older adults often have lower magnesium levels due to reduced intake and absorption, so supplementation makes a much bigger difference.
But, there’s also a direct correlation between stress and magnesium depletion. It’s a vicious cycle. Your body uses up more magnesium when it’s stressed - and a magnesium deficiency leads to more stress.
So if you’re really stressed out, you’re going to need to be patient as your body’s internal magnesium stores are replenished. You can expect it to take a bit longer to get back to baseline.
Nutrient deficiencies - particularly in vitamin D, B6, or calcium - can also affect how well your body utilizes magnesium for sleep support. If you’re also deficient in these nutrients you’ll need to give it more time to replenish them as well.
Tips on Speeding Things Up and Getting a Better Night’s Rest
Patience is a virtue, but you shouldn’t have to wait long for a good night’s rest. There are things you can do to replenish your body’s magnesium stores faster and supercharge the sleep benefits it has to offer. Here are some tips on making the most of magnesium for sleep!
Use Magnesium as Part of a Wind-Down Routine
Magnesium isn’t a magic bullet for sleep. We’re not trying to downplay its benefits, but we do want to be clear that it works best as part of a more comprehensive bedtime routine.
A warm soak with magnesium chloride in the evening helps relax muscles and shift the nervous system into a rest-and-digest state. Dimming the lights, limiting screen use, and keeping your bedroom cool can go a long way in making it easier to fall asleep naturally.
Combine With Sleep-Friendly Nutrients and Habits
Remember, complementary nutrients like glycine, B6, and L-theanine can support magnesium’s calming effects by promoting neurotransmitter balance and lowering cortisol.
It may be worth building out your own sleep-friendly stack with all of these. The truth is, though, we’ve come up with a formulation combining the most bioavailable magnesium chloride with Vitamins A, E, and L-carnitine that works even better.
What you don’t consume is equally important, if not more so. Steer clear of caffeine after noon, and avoid any sort of heavy meals before bed. We also recommend keeping a consistent bedtime routine. These are small shifts that add up when paired together.
Track Results and Adjust Based on How You Feel
It’s worth tracking your sleep habits to get a better sense of how magnesium is working for you. Otherwise, you may not notice a difference. There are plenty of sleep trackers you can buy.
Or, you can just journal how you feel each morning. Take note of better restfulness, fewer wake-ups, or less tension at night. Pay attention to these subtle changes and give the routine at least a week or two before making adjustments.
