How to Choose the Best Magnesium Supplement

Most magnesium supplements on the market don’t actually help your body relax. Here’s what to look for — and what to avoid — if you want real results.

You’ve probably heard that magnesium can help you relax. Or that it can make it easier to fall asleep at night. Or that it can help your body handle stress without falling apart.

And all of that is true — but only if you’re taking the right kind of magnesium.

Because here’s the hard truth: Most magnesium supplements on the market won’t help your body relax. That’s because they’re built on forms your body struggles to absorb. Or they leave out the critical co-factors your nervous system needs to actually feel the difference.

No wonder so many people add magnesium to their routine… and still find themselves wide awake at 2 a.m., staring at the ceiling, replaying the day’s worries on a loop.

The good news? Choosing the right magnesium supplement isn’t complicated once you know what to look for — and what to avoid.

Let’s walk through it.

Choose Magnesium That’s Easy to Absorb

When it comes to magnesium, it’s not how much you take that matters. It’s how much your body can actually absorb.

And that’s where most supplements go wrong.

Walk down any supplement aisle, and you’ll see bottle after bottle boasting about their magnesium content. But take a closer look at the label — and chances are, you’ll find cheap forms of magnesium.

These are easy to manufacture. And on paper, they look impressive because they contain a high percentage of elemental magnesium.

But there’s a catch.

Studies show that only about 4% of these cheaper forms are actually absorbed by the body.¹ The rest simply passes right through your system — giving you little to no benefit.

That’s why so many people feel disappointed. They’re taking the capsules. They’re swallowing the pills. But their nervous system is still stuck in high gear — and their sleep isn’t getting any better.

That’s because they’re not absorbing their magnesium. It’s literally getting flushed out of their body and down the drain. 

If you want magnesium that truly supports relaxation, deeper sleep, and calmer stress levels, you need a supplement made with bioavailable forms — the ones your body can easily recognize and use.

Ideally, you want your magnesium in a blended form that your body can actually absorb. That’s why Magnesium Relax includes magnesium bisglycinate chelate (TRAACS®), which is shown to be up to 4x more absorbable than standard magnesium; Albion® Di-Magnesium Malate, which is 3x more absorbable; and magnesium citrate, a water-soluble form that’s easy to absorb and well-studied for sleep and relaxation. Together, these forms ensure your body doesn’t just ingest magnesium—it actually uses it.

When you combine these three forms — glycinate, citrate, and malate — you give your body the kind of magnesium it actually knows what to do with. Not the kind that ends up wasted.

Because when it comes to magnesium, the right form makes all the difference between feeling frustrated… and finally feeling calm, relaxed, and ready for real sleep.

Choose Magnesium With The Right Co-Factors

Choosing the right magnesium is the first step toward better sleep and calmer days.
But if you really want your nervous system to switch off at night — and stay off — there’s something else you need to know…

Magnesium doesn’t work in isolation. It works best when paired with co-factors that help it to do its job properly.

Without these co-factors, even the best magnesium supplement can fall short.

That’s why the smartest formulas don’t just stop at magnesium. They also include key ingredients like zinc, P5P (the active form of vitamin B6), and calming adaptogens like Sensoril® Ashwagandha.

Together, these ingredients support every part of your body’s relaxation system — from balancing your stress hormones to boosting your brain’s natural sleep signals.

Let’s take a closer look at what they do — and why they matter if you’re serious about real, lasting results.

Choose Magnesium With Sensoril® Ashwagandha

Sensoril® is a patented, full-spectrum extract of ashwagandha — one of the most studied adaptogens in the world. But it’s not just any ashwagandha. Sensoril® is carefully standardized to deliver a potent dose of calming compounds (withanolides) while keeping harsh compounds (like withaferin A) extremely low.

Bottom line? Sensoril® doesn’t sedate you. It resets you.

Here’s how…

Ashwagandha Reduces Feelings Of Occasional Anxiety

In one randomized, double-blind, placebo-controlled study, researchers gave 130 chronically stressed adults 250 mg of Sensoril® per day (125 mg twice daily) for 60 days.²

Then they measured the results using a tool called the Hamilton Anxiety Scale — one of the most trusted assessments used by doctors and psychiatrists to measure anxiety in clinical settings.

Just to be clear. This is not the kind of ‘mood quiz’ you find in magazines. It’s a professional-grade diagnostic tool used in hospitals and research trials.

Patients are asked to rate how often they experience symptoms like:

• Nervousness or fear for no reason
• A racing heart or tightness in the chest
• Trouble sleeping
• Feeling jumpy, irritable, or “on edge”

Each symptom is graded from 0 (not present) to 4 (severe) — and the total score helps clinicians assess how serious the anxiety is.

And the results?

After just 60 days on Sensoril®, participants saw a 62% drop in their scores.

Imagine if nearly two-thirds of your stress just vanished. 

That’s exactly what happened to people who took part in this Sensoril® study.

And that wasn’t the only benefit…

Ashwagandha Helps You Handle Stress

You may not know this, but your body has a resilience hormone called DHEAS. It’s often called the bounce-back hormone — your built-in shock absorber.

When DHEAS is high, you can roll with the punches. But when it’s low? Even the smallest bump feels like a brick wall.

And here’s the thing…

Chronic stress burns through your DHEAS reserves.

That’s when the little things start to feel big. You get snappy, teary, overwhelmed — like you’re barely holding it together.

But in the same 60-day clinical study, participants taking 250 mg (125 mg twice daily) of Sensoril® daily saw their DHEAS levels jump by 32.2%.

That’s like giving your nervous system a cushion — so when life hits hard, you bounce instead of break.

More DHEAS =

✔ Greater emotional resilience
✔ Better hormonal balance
✔ And the ability to handle life without falling apart

In other words?

It helps you feel more like you again.

And that’s not all the Sensoril® researchers discovered. 

Ashwagandha Gives Your Mind Permission To Relax

You’ve probably heard of cortisol. It’s your body’s main stress hormone — designed to help you survive danger. Like when your ancestors had to run away from a sabre-tooth tiger.

But here’s the problem…

Cortisol isn’t supposed to stay high. It’s built for short bursts — not endless marathons.

Yet when you’re under constant stress?
Your cortisol never shuts off.
And your brain stays on high-alert.

And you feel it — that wired-but-exhausted feeling that won’t quit. 

Like your whole system forgot how to wind down.

That’s why this next result from the Sensoril® studies³ is such a big deal:

Cortisol levels dropped by 24.2% in just 60 days. And for many of the study participants, that was the moment everything changed.

The noise quieted.
The tension faded.
And for the first time in months — they slept.

Not because they tried harder to relax.
But because their nervous system finally allowed it.

Ashwagandha Tells Your Body: “You’re Safe.”

There’s a little-known biomarker in your body called CRP — short for C-reactive protein. It’s produced by your liver whenever your system senses a threat.

In small doses it’s helpful. Like when you’ve got the flu, or sprained your ankle.

But under chronic stress your CRP stays high.

And your entire nervous system gets stuck in defense mode.

Which means your brain never gets the memo to shut off.

And no matter how tired you are… you can’t relax.

That’s what made this next finding so remarkable:

In a 60-day double-blind, placebo-controlled trial⁴, researchers found that CRP levels dropped by 36.6% in participants taking 250 mg (125 mg twice daily) of Sensoril®.

That’s not just a small change — it’s a biochemical green light.

A message to your body that says: “You’re safe. It’s okay to rest.”

And for many participants, that shift in CRP came right alongside deeper sleep, calmer moods, and clearer thinking.

Because when the emergency signal shuts off?

Your whole system can finally relax.

How Sensoril® Ashwagandha Works

Most so-called “stress supplements” just take the edge off. They dull you. Sedate you. Numb you out.

But Sensoril® doesn’t do that.

It doesn’t knock you out — it helps you reset.

How?

By calming the very system that creates your stress response:

Your HPA axis.

That’s the communication loop between your brain and your adrenal glands. When you’re under pressure — emotionally, physically, or mentally — here’s what happens:

Your Hypothalamus → sends a signal to
Your Pituitary gland → which tells
Your Adrenal glands → to pump out cortisol (your main stress hormone)

That’s your HPA axis in action.

It’s useful when you’re in danger. But when it stays stuck in the “on” position?

Your nervous system never gets to power down. You feel wired. Jittery. Exhausted. And no amount of deep breathing or melatonin can fix it.

Sensoril® helps regulate this loop — so you’re not constantly running on adrenaline.

That’s why the above studies showed a 24.2% reduction in cortisol after just 60 days.

In other words?

Sensoril® doesn’t mask your stress. It rewires the system causing it.

And with zero reported side effects in multiple clinical trials, it’s one of the safest and most effective ways to feel like yourself again.

So you can see why it’s a good idea to choose a magnesium supplement that includes a clinical dose of Sensoril®. Now let’s talk about what happens when you add zinc to the mix…

Choose Magnesium With Zinc

When it comes to choosing the best magnesium supplement it’s a good idea to check the label for zinc. 

That’s because zinc helps your body produce melatonin — the hormone that tells your brain it’s time to wind down and go to sleep. It also helps keep cortisol (your main stress hormone) in balance, so you’re not lying awake feeling wired when you should be resting.

And the research is clear.

In a double-blind, placebo-controlled study⁵, researchers looked at one of the most high-pressure professions in the world: ICU nurses. Long hours, life-or-death decisions, endless alarms — and no room for error.

More than half of the nurses in the study reported poor sleep. Over 80% said they were under extreme stress. And nearly a quarter relied on sleep medications just to get through the night.

So researchers asked a simple question: what happens if you give them zinc?

The results were remarkable.

• They fell asleep faster. The nurses in the study reported falling asleep up to 30 minutes faster each night!
• They stayed asleep longer. Study participants went from sleeping less than 6 hours a night to closer to 7 or more. That’s 30 extra hours of sleep each month!

Let that sink in. Zinc helped real people — working in one of the most sleep-deprived, stress-saturated environments in healthcare — actually sleep better.

Naturally. Safely. Without a single reported side effect. 

So you can see why it’s a good idea to choose a magnesium supplement with zinc. And that’s not all. It’s also worthwhile checking to see whether your magnesium supplement includes vitamin B6. 

Choose Magnesium With The Right Form Of B6

Magnesium, Sensoril® and zinc lay the groundwork for a calm mind, relaxed body, and deeper sleep. But if your brain still feels like it’s stuck in overdrive at night, there’s a good chance you’re missing one last critical piece: vitamin B6.

Specifically, the active form of vitamin B6 — known as P5P (pyridoxal-5-phosphate).

Here’s why it matters:

Your brain relies on P5P to produce GABA — the calming neurotransmitter that slows racing thoughts, quiets overstimulation, and helps you shift from “fight or flight” into real rest.

Without enough GABA, your mind stays active when you want it to slow down. You lie in bed, exhausted but wired, replaying conversations, worries, and to-do lists in an endless loop.

And here’s the problem:

Most magnesium supplements that include vitamin B6 use the wrong form — pyridoxine. It’s a cheaper, synthetic version that your body has to convert into active P5P before it can be used.

But stress, aging, common medications, and even genetics can block that conversion process — leaving you stuck with inactive B6 that your brain can’t actually use.

That’s why supplementing with P5P directly makes such a difference.

It skips the conversion step entirely — giving your brain the building blocks it needs to naturally boost GABA levels, quiet the mental noise, and finally let you relax into real, restorative sleep.

And it’s not just theory.

A 2021 review⁶ published in Nutrients confirmed that P5P supplementation helps:

• Increase GABA production
• Reduce brain excitability
• Promote a calmer, more balanced mood

So, when you combine the right forms of magnesium, zinc, and P5P — and pair them with clinically supported adaptogens like Sensoril® — you give your body the full toolkit it needs to finally relax, reset, and sleep the way nature intended.

Until now, finding all those ingredients together — in the right forms and the right doses — has been nearly impossible.

But that’s about to change.
