And no, this isn’t another wellness trend, it’s real, science-backed, and more common than you think.
Your Body Is Calling for Help.
You tell yourself it's normal.
The 3PM crash. The brain fog. The short fuse. The endless craving for coffee, sugar, something anything to get you through the day.
You’re not lazy. You’re not broken.
You’re likely missing one of the most essential nutrients your body depends on and it’s more common than you think.
Magnesium.
It powers your energy.
It calms your nervous system.
It helps you sleep, move, focus, and recover.
And yet, more than 1 in 2 Australians aren’t getting enough, not because they don’t care, but because no one’s told them to (Fatima et al., 2024).
If you’re wired but exhausted… sleeping but never rested… training but not recovering… this blog is for you.
Because this isn’t about a trendy supplement. It’s about a quiet deficiency that’s stealing your energy, your calm, and your ability to reset, day after day.
Let’s change that.
How to Know If You’re Low — The Functional Checklist
You don’t need a clinical diagnosis to know something’s off.
If you’ve been feeling flat, foggy, or just not like yourself, this could be your body’s quiet call for magnesium.
Forget the blood test. These are the real-world signs of deficiency:
Waking up tired, even after 7–8 hours of sleep
Craving chocolate, coffee, or salty foods mid-afternoon
Muscle tightness, cramps, or post-workout soreness
Feeling edgy, overwhelmed, or anxious for no clear reason
Twitching eyelids or restless legs, especially at night
Constipation, bloating, or sluggish digestion
Difficulty winding down at the end of the day
PMS, irritability, or mood swings
Brain fog or afternoon crashes
Heart palpitations or irregular heartbeat under stress
If you tick more than two?
Magnesium is a very good place to start (Fatima et al., 2024).
What’s Draining Your Magnesium Every Day
Even if you eat well, modern life burns through magnesium faster than most people realise (Fatima et al., 2024).
Caffeine: Coffee increases urinary magnesium loss (Fatima et al., 2024).
Alcohol: Acts as a diuretic, pushing magnesium out of the body (Fatima et al., 2024).
Common medications: Antacids, proton pump inhibitors (PPIs), antibiotics, diuretics — all interfere with magnesium absorption or increase losses (Fatima et al., 2024).
Chronic stress: Your body uses magnesium to regulate the stress response, meaning the more stressed you are, the more magnesium you deplete (Fatima et al., 2024).
Exercise and sweating: Athletes and active people lose magnesium through sweat and increased metabolic demands (Kaczorowski et al., 2024).
It’s not about poor choices — it’s about a system that’s out of balance.
And if you’re not actively replenishing, you’re likely running on empty.
Why Magnesium Matters (More Than You’ve Been Told)
You’ve tried the quick fixes.
Another coffee. A new pre-workout. That influencer-backed fat burner.
But what if your body isn’t asking for more stimulation — it’s asking for support?
In the supplement world, we hear a lot about protein, fat burners, and pre-workouts. But we rarely hear about the mineral that quietly fuels the systems behind it all: magnesium (Fatima et al., 2024).
Magnesium isn’t flashy. It doesn’t promise instant results.
But it is involved in over 300 enzymatic and 600 coenzymatic processes that keep your body functioning day to day (Fatima et al., 2024).
That’s not hype. That’s biology.
Magnesium Powers Key Systems Like:
Cardiovascular Function
Your heart is a muscle. Magnesium helps regulate heartbeat, blood pressure, and vascular relaxation (Fatima et al., 2024).
Low magnesium has been linked to hypertension, palpitations, and increased cardiovascular risk (Fatima et al., 2024).
Energy Production and Muscle Recovery
Magnesium is essential for converting food into ATP — your body’s energy molecule (Fatima et al., 2024; Kaczorowski et al., 2024).
It also regulates calcium flow in muscle cells, influencing contraction, relaxation, and recovery (Kaczorowski et al., 2024).
Metabolic Balance and Blood Sugar Control
Magnesium helps regulate insulin sensitivity and blood sugar levels (Fatima et al., 2024).
Deficiency leads to cravings, crashes, and metabolic dysfunction — even when your diet looks "clean."
Personalised Supplementation: Finding What Works for You
There is no one-size-fits-all when it comes to magnesium.
What works for one person, like magnesium glycinate for sleep, might not work for someone else who needs citrate for digestion, or malate for muscle fatigue.
And for many people, a blended magnesium formula combining glycinate, malate, and citrate covers more ground, supporting nervous system recovery, energy production, and muscle relaxation at once (Fatima et al., 2024).
Smart Supplementation: What You Need to Know
Form |
Best For |
Magnesium glycinate |
Sleep, anxiety, nervous system support (Fatima et al., 2024) |
Magnesium citrate |
Constipation, digestion support (Fatima et al., 2024) |
Magnesium threonate |
Cognitive function, brain fog (Fatima et al., 2024) |
Magnesium malate |
Energy production, muscle fatigue (Fatima et al., 2024) |
Magnesium orotate |
Heart health, cardiovascular recovery (Fatima et al., 2024) |
Timing and Usage Tips
- Take magnesium in the evening for stress, sleep, or recovery (Fatima et al., 2024).
- Always take with food to enhance absorption and minimise digestive upset.
- Start with a lower dose and build up gradually, especially with citrate, which can act as a laxative in higher doses.
The Stress–Magnesium Cycle: Breaking the Loop
Stress burns through magnesium faster. Low magnesium makes your stress response worse (Fatima et al., 2024).
This creates a vicious cycle that leaves your nervous system overworked, your sleep disrupted, and your recovery stalled (Fatima et al., 2024).
Replenishing magnesium helps restore calm, improve resilience, and regulate your body’s response to daily pressure.

Real Change Starts with the Basics
You don’t need another quick fix.
You need real foundations — the building blocks your body has been missing.
Magnesium isn’t a miracle cure.
It’s a mineral your body can't function without — and for thousands of Australians, replenishing it has been the first step to sleeping better, thinking clearer, moving easier, and feeling resilient again (Fatima et al., 2024).
This is your reset moment.
Not for perfection, but for progress.
Start with magnesium.
Start with what your body has been asking for.
Start with ASN.
Magnesium deficiency is extremely common — over half of Australians don't get enough.
Symptoms include: fatigue, brain fog, cravings, anxiety, muscle cramps, digestive issues, sleep problems, and heart palpitations.
Blood tests often miss it — only 1% of magnesium is in the blood; most is stored in muscles, bones, and organs.
Modern lifestyles deplete magnesium faster: Stress, Caffeine, Alcohol, Medications (antacids, PPIs, antibiotics, diuretics), Exercise and sweating.
Magnesium powers key systems: Nervous system (calm, emotional balance), Heart health (heartbeat, blood pressure), Energy production (ATP creation, muscle recovery), Metabolic balance (insulin sensitivity, blood sugar control).
The stress–magnesium cycle: Stress burns magnesium → Low magnesium worsens stress → Repeat unless corrected.
