Which Magnesium is Best for Sleep? - Flewd Stresscare

Sleepless nights take a toll on your physical and mental wellbeing. It can bleed into your performance at work or athletically, and the grumpies are real when you’re not well-rested. 

With competitive price and timely delivery, T&P sincerely hope to be your supplier and partner.

While everyone seems to turn to melatonin as a way to overcome insomnia, it leaves you feeling groggy the next day - that’s why we always recommend magnesium for sleep as a better alternative.

However, not all magnesium is created equal. You need the best magnesium for sleep - one that works well without any uncomfortable side effects. So which magnesium is best for sleep?

Although you’ll see people recommend magnesium glycinate, citrate, threonate, malate, and even oxide, magnesium chloride is the most bioavailable form on the market. It’s the form we use in our magnesium bath soak.

It’s time to stop tossing and turning. Wake up feeling refreshed and invigorated using our Insomnia Ending Soak, which also features vitamins A & E with natural L-carnitine to help you drift away to dreamland.

How Magnesium Supports a Better Night’s Sleep

You’re probably familiar with some of what magnesium does - but given the fact it plays a role in more than 300 bodily processes, so many people underestimate its importance in human health.

Its primary functions are linked to muscle relaxation, nerve function, and stress regulation. So, how does magnesium support sleep? It stimulates gamma-aminobutyric acid (GABA) production.

This neurotransmitter slows down brain activity so you have less trouble falling asleep. In other words, decreased GABA activity is associated with racing thoughts, restlessness, and in turn, poor sleep quality. If you ever feel like you can’t stop thinking at night, this is probably why.

Cortisol plays a part in keeping you awake as well, though. This stress hormone also stirs up an overactive mind. Magnesium regulates it to keep it at bay. Magnesium also supports melatonin production, the hormone that regulates your sleep-wake cycle.

If your body feels restless at night, magnesium can help there, too. It calms tense, spastic muscles - which is why pregnant women use it at night to manage restless leg syndrome (RLS). 

But the truth is, anyone who struggles with frequent nighttime awakenings or who can’t even fall asleep in the first place can benefit from incorporating the best magnesium for sleep into their bedtime routine.

Which Magnesium is Best for Sleep?

It’s not as simple as finding the first magnesium sleep supplement and adding it to your regimen. Some forms have low bioavailability so they won’t be as effective or efficient. Others cause more harm than good with side effects such as digestive discomfort.

That being said, which magnesium is best for sleep? We’ll help you weigh all your options below, but look no further than magnesium chloride, the star of the show in the best magnesium soak for sleep.

Magnesium Chloride

Bioavailability speaks to how easily your body can absorb and utilize a substance. Low bioavailability means you’re taking a lot of something, and it’s not really moving the needle. 

That’s why the high-bioavailability magnesium chloride is the best magnesium for sleep - especially when used transdermally! You can massage it into your skin or better yet, tap into the magnesium soak benefits.

This method bypasses the digestive system so you can avoid all the uncomfortable side effects oral magnesium supplements are notorious for. It also distributes magnesium efficiently throughout the entire body for the most comprehensive benefits.

Topical magnesium chloride supplementation also leads to rapid results. You can soak right before bed, and you’ll already feel your mind and body winding down by the time you get out of the tub. Order today at Flewd Stresscare and see why this is the #1 epsom salt alternative.

Magnesium Glycinate

Which magnesium is best for sleep if you just want to use an oral supplement, though? Magnesium soaks aren’t so practical when you’re on the road, but whether it’s for business or pleasure, traveling is when you need the most sleep. Magnesium glycinate is a great choice.

This form of magnesium is bound to glycine, an amino acid with calming properties to help lull your body and mind into a deep, restful state. This helps keep stress-related sleep disturbances at bay.

Although magnesium glycinate is fairly well-absorbed, all forms of oral supplementation tend to be associated with questionable bioavailability. You might counter this by taking higher doses, but this can lead to those uncomfortable digestive side effects we mentioned above. 

Magnesium L-Threonate

This specialized form of magnesium is often listed as the best magnesium for sleep since it has a unique ability to cross the blood-brain barrier, providing quick relaxation and turning down the volume on racing thoughts.

Just be aware there is much less evidence on magnesium L-threonate specifically related to sleep. It might not be quite as effective as magnesium chloride or glycinate.

Magnesium Malate

Most people are drawn to magnesium malate for energy support or for a muscle bath soak to provide relief from soreness. So why is it being mentioned on this list of which magnesium is best for sleep?

Truthfully, it’s only going to make sense for anyone who’s sleep struggles are linked to chronic fatigue or fibromyalgia-related discomfort. If that’s not the case for you, stick with one of the other forms listed above. 

Magnesium Oxide

This is one of the most common forms of magnesium you’ll find, but is it the best magnesium for sleep? Not by a long shot. The problem with magnesium oxide is it’s so poorly absorbed that it ends up working more as a laxative than a sleep aid.

Although it contains a really high percentage of elemental magnesium, the human body has a hard time processing it effectively and actually making use of it. Steer clear of this form, as it’s really just going to make sleep problems worse since you’ll be on the toilet all night!

Magnesium Citrate

Magnesium citrate is another readily available and affordable form of magnesium, but it was put last on this list for a reason. While it may be better absorbed than magnesium oxide, it still has a really strong laxative effect, limiting its use for sleep support.

Now, if you’re having trouble with constipation, by all means, give magnesium citrate a shot. Otherwise, stick with magnesium chloride, the best magnesium for sleep by far.

How Much Magnesium for Sleep Should You Take?

There are two questions we get asked all the time about using magnesium to fall asleep and stay asleep. Which magnesium is best for sleep, of course, but also how much magnesium for sleep should you take?

There’s really no one-size-fits-all answer as it depends on how much magnesium you’re getting from other sources (like diet or through soaks), but here are the general guidelines:

  • Men: 400-420 mg per day
  • Women: 310-320 mg per day

We’ve seen sleep experts suggest taking 200-400 mg of magnesium before bed for the best results. As we touched on throughout this guide on the best magnesium for sleep, though, oral supplements - whether powder, pills, or tablets - are linked to digestive discomfort.

Bloating, diarrhea, and stomach cramps are all too common in higher doses of magnesium. It’s a catch-22 because you need high doses of magnesium for it to make a difference in your sleep quality and quantity.

Even better-absorbed forms like glycinate can lose effectiveness due to poor gut absorption rates and individual digestive sensitivities. That’s why we always recommend topical magnesium vs oral.  

Wait, does magnesium soak into the skin? It sure does! We touched on this a bit in highlighting the benefits of magnesium chloride. This approach completely bypasses the digestive system so there’s no risk of stomach discomfort, and you can guarantee high bioavailability.

Transdermal magnesium is definitely your best bet if you want an effective and gentle way to deliver magnesium directly to the bloodstream for faster relaxation and better sleep. That being said, it’s time for you to get your hands on the best magnesium for sleep at Flewd Stresscare.

Strategies to Try in Conjunction With the Best Magnesium Supplement for Sleep

Before we wrap up our guide to which magnesium is best for sleep it’s important that we remind you this mineral is only one piece of the puzzle. Sure, it can make a massive difference in both sleep quantity and quality - but you need to pair it with other healthy sleep habits, including:

  • Stick to a Consistent Sleep Schedule: Go to bed and wake up at the same time every day (yes, even on weekends) to regulate your body’s internal clock.
  • Limit Blue Light Exposure Before Bed: Avoid screens at least 60 minutes before bedtime to let your body’s natural melatonin production process kick into gear.
  • Create a Relaxing Wind-Down Routine: Instead of watching TV or doom-scrolling on your , you can read, practice deep breathing, or take a warm magnesium-infused bath. These things will signal to your body that it’s time to sleep.
  • Avoid Caffeine and Alcohol in the Evening: Both of these can disrupt sleep cycles and prevent deep, restorative rest. No more caffeine after 2-3 P.M., and know that even one drink will impair sleep quality. 
  • Keep Your Bedroom Cool and Dark: A temperature between 60-67°F and blackout curtains are non-negotiables for creating the ideal sleep environment. You might even want a fan or white noise machine.
  • Try Gentle Stretching or Yoga: Light movement before bed helps relieve tension and primes your body for sleep.
  • Manage Stress Levels: Meditation, journaling, or mindful breathing can reduce nighttime restlessness. Our soaks go a long way in doing this as well, though.

But the best thing you can do to overcome your sleep woes is ordering your Insomnia Ending soak at Flewd Stresscare today. See firsthand how it can help you get a good night’s rest!
