A BAD NIGHT MAKES A LONG DAY
You sleep. But do you actually rest?
You wake up tired, lose focus, and in the evening you can't switch off? Here's how a bad night can carry over into the day.
Small things become big.
Concentration slips, patience gets shorter. Even routine tasks feel heavier.
The body is tired. The mind isn't.
You want to rest, but the tasks keep going in your head. And tomorrow the cycle starts again.

HOURS DON'T TELL THE WHOLE STORY
More than hours. Real rest.
8 hours in bed isn't necessarily 8 hours of quality sleep. Frequent waking can leave you unrested.
Quality and duration both matter. Most adults need 7–9 hours of sleep. MAG CORE does not replace the hours you need. Sleep guidelines ↗
THIS IS THE REST YOU WANT
Imagine the day after a good night.
Clearer thoughts. More calm. Energy for life after work. These are benefits of good sleep, not a guaranteed effect of the supplement.
Being here. Really.
In the conversation, in the task, in the moment. Without feeling like your thoughts are passing through fog.
More patience.
For your loved ones, the day's little surprises and yourself.
Having energy left.
For a walk, a workout or dinner with friends. Not just for the sofa.
Rest that makes sense.
Time for recovery. Not a lost part of the day.
MEET MAG CORE
Two forms. One clear formula.
3 capsules provide 300 mg magnesium from bisglycinate and malate, complemented by taurine and 6 mg vitamin B6 (P5P).
Magnesium and B6 contribute to normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue. MAG CORE is not a sleeping pill.

HOW MAG CORE SUPPORTS THE BASICS
Four ingredients. No extra noise.
What 3 capsules contain — and the role of each ingredient.
180 mg elemental magnesium
Bisglycinate
Magnesium contributes to normal functioning of the nervous system and normal psychological function.
See the full formula in MAG CORE ↗120 mg elemental magnesium
Malate
Brings the daily intake to 300 mg magnesium. Magnesium contributes to normal energy-yielding metabolism, muscle function and the reduction of tiredness and fatigue.
See the full formula in MAG CORE ↗360 mg per daily dose
Taurine
Part of the four-ingredient formula. We don't attribute a proven effect of taurine on sleep to this combination.
See the full formula in MAG CORE ↗6 mg as P5P per daily dose
Vitamin B6
The active form pyridoxal-5-phosphate. Vitamin B6 contributes to normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue.
See the full formula in MAG CORE ↗4 ingredients.One clear formula.
Amounts per 3 capsules. There is no EU-authorised claim that magnesium, taurine or B6 cure insomnia. The stated functions of magnesium and B6 are authorised nutrition health claims.
BENEATH THE SURFACE OF A GOOD NIGHT
Sleep isn't a single button.
Nerve signals. Stress response. Muscle function. Explore six links that explain why the ingredients matter — and how far the data goes.
IN THE NERVOUS SYSTEM
- Magnesium
- involved inRegulation of NMDA receptors
- involved inNerve activity
Simplified diagram of a biological role, not a measurement of sleep.
Established biological role
The nervous system has regulators too.
Magnesium is involved in controlling the activity of NMDA receptors — part of the system that transmits nerve signals. Think of a regulator, not a button that switches the brain off.
In MAG CORE
300 mg magnesium from bisglycinate and malate in 3 capsules. Magnesium contributes to normal functioning of the nervous system.
How do we know this?
NMDA channels are one of the mechanisms studied. The existence of a mechanism doesn't prove that extra intake improves sleep in every person.
Nowak et al. · NMDA and magnesium ↗
Authorised functions of magnesium ↗
LINKS UNDER STUDY
- Magnesium status
- studied linkStress system
- studied linkCortisol and sleep
This is not a proven causal chain in every person.
Limited human + animal data
When the day doesn't end when you go to bed.
Sleep and the stress response are linked. Magnesium status is part of the picture being studied: in animals, deficiency alters the stress system; a small study in older adults reports changes in night-time cortisol and sleep.
In MAG CORE
300 mg magnesium in 3 capsules. Magnesium contributes to normal psychological function and normal functioning of the nervous system.
How do we know this?
Held et al. studied 12 people aged 60–80 with different, higher doses and another form of magnesium. They report lower cortisol in the first part of the night and more slow-wave sleep.
The link deficiency → disrupted stress response has also been shown in mice, but it doesn't prove that every person with a shortfall has high night-time cortisol. A separate human study shows that sleep loss itself can raise cortisol the following evening.

STUDIED WITH FREE GLYCINE
- 3 g glycine on its own
- tracked in a studyTime to fall asleep
- tracked in a studySelf-rated sleep quality
3 g is the dose of free glycine in the study, not intake guidance.
Small studies with free glycine
What's behind the “gly” in bisglycinate?
Glycine is the amino acid that magnesium is bound to in bisglycinate. In small studies, 3 g of glycine on its own before bed was linked to a shorter time to fall asleep and better self-rated sleep.
In MAG CORE
In MAG CORE, glycine is bound to magnesium in the bisglycinate; there is no separate confirmed dose of 3 g free glycine.
How do we know this?
The study by Yamadera et al. used free glycine and tracked sleep with a questionnaire and polysomnography.
Thermoregulation is also discussed — the natural drop in body temperature around sleep. Data on this glycine mechanism comes mainly from animal experiments.
Yamadera et al., 2007 ↗
Glycine: human data and context for the mechanism ↗
HOW THE BODY USES B6
- B6 / P5P
- involved inEnzymes for neurotransmitter synthesis
- involved inGABA and serotonin
A biochemical role. More B6 doesn't automatically mean more sleep.
Established biological role
The helper behind chemical signals.
The body uses vitamin B6 as a helper for enzymes, including in making GABA and serotonin. This is part of normal communication between nerve cells.
In MAG CORE
6 mg vitamin B6 as P5P in 3 capsules. B6 contributes to normal nervous and psychological function.
How do we know this?
P5P is a coenzyme form of B6. Its role in neurotransmitter synthesis doesn't prove that 6 mg improves sleep or increases melatonin.
NIH · biological roles of B6 ↗
B6 and GABA · study and mechanism ↗
OBSERVED IN MOUSE CELLS
- Taurine
- interaction in a modelGABA and glycine receptors
- interaction in a modelNeuronal excitability
Cellular mechanism ≠ proven effect on sleep in humans.
Laboratory data · not a human trial
Another link with nerve signals.
In mouse nerve cells, taurine interacts with GABA and glycine receptors and changes their excitability. This explains the scientific interest in it, but doesn't prove better sleep after taking a supplement.
In MAG CORE
360 mg taurine in the daily dose of 3 capsules.
How do we know this?
Jia et al. tracked receptor activity in the mouse thalamus, not the sleep of people taking 360 mg taurine. Concentrations in a cell experiment are not equivalent to a capsule dose.
THREE NORMAL FUNCTIONS
- Muscle function
- magnesium contributes toElectrolyte balance
- magnesium contributes toEnergy metabolism
Three separate functions, not sequential effects on sleep.
Authorised functions of magnesium
Not just the mind. The body too.
Magnesium contributes to normal muscle function, electrolyte balance and energy-yielding metabolism. These are everyday body functions — part of the bigger picture of recovery.
In MAG CORE
180 mg magnesium from bisglycinate + 120 mg from malate = 300 mg in total per daily dose.
How do we know this?
These functions don't mean instant muscle relaxation, treatment of cramps or deeper sleep. The forms add up to the total amount of magnesium; malate has no separately proven effect on sleep in this formula.
WHY MAGNESIUM BISGLYCINATE
Studied in people with poor sleep.
Bisglycinate is one of the two forms of magnesium in MAG CORE. In a randomised, placebo-controlled study from 2025, researchers tracked how taking it affected people with complaints of poor sleep.
Adults with poor sleep
Randomly assigned to a bisglycinate or placebo group.
Intake period
Daily intake and tracking of self-rated symptoms.
As bisglycinate
The amount is elemental magnesium taken daily in the study.
Fewer insomnia complaints.
After 4 weeks, the bisglycinate group reported a greater improvement on the Insomnia Severity Index (ISI) than placebo.
SMALL CHANGES, STARTING TONIGHT
Make room for a quieter evening.
Three habits you can repeat tomorrow too. Practical guidance ↗
Protect time for sleep
Go to bed and get up at similar times. Plan enough hours for sleep.
Turn down the noise
Put work and bright screens aside. Late caffeine and alcohol can disrupt sleep.
Prepare the space
A dark, quiet and cool bedroom. A few pages of a book. A signal that the day is over.
A SMALL STEP. EVERY DAY.
Choose your MAG CORE.
300 mg magnesium from bisglycinate and malate, with taurine and 6 mg vitamin B6 in a daily dose of 3 capsules. 90 capsules · 30 daily doses.
The daily figure is a calculation for the subscription, not a daily charge. Food supplement. Not a substitute for a varied diet and a healthy lifestyle.
CLARITY BEFORE YOU ORDER
A few honest answers.
What do studies show about magnesium and sleep?
In a 2025 study of 155 adults, 250 mg magnesium as bisglycinate daily for 4 weeks led to a small improvement in self-rated insomnia symptoms compared with placebo.
The results come from questionnaires, with no objective measurement of sleep. Schuster et al., 2025 · PubMed ↗
What is magnesium's proven purpose?
Magnesium contributes to normal functioning of the nervous system and muscles, normal psychological function and the reduction of tiredness and fatigue. These are authorised nutrition claims, not a promise to treat insomnia. Regulation (EU) No 432/2012 ↗
When and how should I take MAG CORE?
Our recommended daily dose is 3 capsules with water.
You can split the intake into two — for example 1 capsule in the afternoon and 2 in the evening. If you take all three capsules at once, follow the label directions and your personal tolerance.
Focus on consistency: choose a routine that suits you and that you can follow every day. Do not exceed the recommended daily dose.
Will I feel a change on the very first night?
There's no guaranteed timeframe or guaranteed result. Sleep depends on many factors, and taking magnesium doesn't solve every cause of poor sleep.
What if I still wake up tired?
For persistent sleep problems, severe daytime sleepiness or snoring with pauses in breathing, see a doctor. If you have kidney disease, are pregnant, breastfeeding or taking medication, discuss the supplement with a healthcare professional.
Does the subscription charge me every day?
No. The per-day figure shown is calculated over 90 days. The subscription order is for 3 bottles, with delivery and billing every 3 months. You can also choose a one-time order without a subscription.
FOR THE MORNING YOU LOOK FORWARD TO
