Calm in three sips
No routine to learn, no pills to swallow. One tasty tube on your nightstand.
One 12g blue-vanilla liquid tube in the evening — stir into 300ml water or yoghurt. No pills, no chalky powder.
Liquid Magtein® L-threonate crosses the blood–brain barrier while the other forms top up the body.
Nervous system calms, muscles relax — you drift into deeper REM sleep and wake clear, not groggy.
Who it’s for
If any of these sound like your evenings, your magnesium tank is probably running low.
You toss, turn or wake at 3am, then drag through the next day feeling un-rested.
Deeper sleepA mind that won’t switch off — stress, long hours and a head full of tomorrow’s to-do list.
Calmer nightsCoffee from morning to evening, rarely a real moment of rest in between.
Reset the systemNight cramps, twitchy legs or muscle stiffness that flares when you’re run down.
Relaxed musclesStudents and professionals who need clear, calm, switched-on concentration.
Sharper focusOlder adults wanting to protect memory, sleep quality and brain magnesium for the long run.

Meet Magtein® — magnesium that reaches your brain
Most magnesium supports the body but stops at the brain’s door. Magtein® Magnesium L-Threonate is the one form clinically shown to cross the blood–brain barrier.
it
Ordinary magnesium supports the body, but very little reaches the brain — it can’t cross the blood–brain barrier.
Magnesium L-threonate is bound to threonic acid, the one form clinically shown to cross into the brain.
It lifts magnesium levels right at the synapse — studies show a ~15% increase in brain magnesium.
Higher brain magnesium supports deeper REM sleep, lower stress and noticeably sharper focus.
Not one magnesium — four
Each form is absorbed differently and reaches a different place. Together they cover brain, body, calm and absorption.
The only magnesium proven to cross the blood–brain barrier — raising brain magnesium for memory, focus and calm.
Chelated with glycine for gentle, highly-absorbable magnesium that soothes the nervous system without upset.
A fast, well-absorbed form that relaxes muscles, eases cramps and keeps everyday magnesium levels topped up.
Wrapped in liposomes to protect the magnesium through digestion and boost how much actually gets used.

One tube, four systems
Where the magnesium goes and what it does. Tap through brain, sleep, mind and digestion.
Magnesium for the synapse
Magtein® raises magnesium right where neurons connect — supporting synaptic density, signalling and the plasticity behind memory and learning.
Deeper, more restorative nights
By calming the nervous system and relaxing muscle, magnesium helps you fall asleep and stay in the deep, REM-rich stages that actually restore you.
Regulates the stress response
Magnesium, glycine and L-theanine help quiet an overactive nervous system and regulate cortisol — so the mental chatter settles and stress eases.
Eases and regulates digestion
Magnesium draws water into the intestine and relaxes the smooth muscle of the digestive tract — supporting gentle, regular, comfortable digestion.

Calmer nights, real reviews
I’ve struggled with 3am wake-ups forever. Two weeks of the evening tube and I’m sleeping through — and the blue vanilla taste is genuinely lovely.
I’m a chronic over-thinker. This doesn’t knock me out, it just quiets the noise so I can actually relax. Mornings feel clearer too.
The calf cramps that used to wake me up are basically gone. I take it after dinner and it’s become the nicest part of my wind-down.

Questions, answered.
Magtein® (Magnesium L-threonate) is the only form clinically shown to cross the blood–brain barrier, raising magnesium directly in the brain. That’s what supports deeper sleep, lower stress and sharper focus — not just topping up the body like standard magnesium.
Most people feel more relaxed and notice deeper sleep within 7–14 days of consistent evening use. Focus and stress-resilience benefits build over the following weeks as brain magnesium replenishes.
It isn’t a drug — there are no sedatives and it’s non-habit-forming. Magnesium is a nutrient your body recognises and uses. It helps you reach deep sleep naturally, rather than knocking you out.
No. The formula calms the nervous system without sedation, so you stay focused and energised. Many people take it in the evening, but it won’t leave you groggy.
One 12g tube daily, preferably in the evening or before bed. Mix into about 300ml of water, or stir into yoghurt. It’s a delicious blue-vanilla drink — no pills, no fishy taste.
Four magnesiums (L-threonate, bisglycinate, citrate and liposomal) plus taurine, glycine, L-theanine, L-tyrosine, zinc, vitamin D3, B6 and selenium. Free from gluten, dairy, soy, nuts and common allergens, with natural blue colour from spirulina.
