THE NIGHT-TIME STRUGGLE NO ONE SEES

Exhausted All Day. Wide Awake at Night.

It's 2am. Your body is exhausted. Your mind won't stop. You replay conversations from three days ago. Rehearse tomorrow's to-do list. Check the clock. Promise yourself you'll sleep now — then look again ten minutes later. You wake up more tired than when you went to bed. Your brain feels wrapped in fog. Small things irritate you. Your energy disappears before the day has properly started. Your muscles ache. Your jaw is clenched. Your shoulders never quite drop. You don't even notice anymore — this has become your normal. And when night comes again, you dread the same familiar battle: tired body, switched-on nervous system, another day waiting on the other side. This is not a willpower problem. Your body may be asking for the mineral that supports normal nervous system and muscle function — the missing piece that can help you feel ready for the answer.
2am. Still awake.

Your body is desperate for rest. Your mind is replaying everything — tomorrow, yesterday, and every conversation in between.

Exhausted on waking.

You open your eyes already drained. Brain fog follows you into the morning, and your energy runs out far too early.

Tension that won't let go.

Your jaw is tight. Your shoulders are up by your ears. Irritability, restless muscles and anxiety follow you from daylight into bed.

THE MAGNESIUM GLYCINATE AHA MOMENT

Your Body Is Tired. Your Nervous System Just Needs Help Switching Off.

Meet PureBioClinic Magnesium Glycinate — a high-absorption form designed to give your body magnesium it can actually use. Magnesium contributes to the normal functioning of the nervous system, normal psychological function, normal muscle function, and the reduction of tiredness and fatigue. That connects directly to the nights you cannot switch off, the tense muscles you carry into bed, and the mornings you start already depleted. This is not a sedative. It does not force sleep. It supports the systems that help your body wind down naturally. One capsule before bed. A simpler evening. A calmer night to look forward to.
300+
300+ enzymatic reactions depend on magnesium — including the systems behind energy, nerves and muscle function.
1
one easy capsule before bed — no powders, measuring or complicated routine.
0
no sedatives and no forced crash — just high-absorption Magnesium Glycinate supporting your nightly wind-down.

Your Magnesium Glycinate Journey

NIGHT 1–3

Night 1 — A Different Kind of Bedtime

The first thing most people notice is the edge coming off the evening. Muscles feel less tightly wound. Lying down stops feeling like a fight.

WEEK 1–2

Topping Up the Tank

You are replenishing your magnesium consistently. Your evening routine feels calmer, your muscles feel less wound up, and the next morning begins with a little more in reserve.

WEEK 3–4

Daytime Payoff

This is where the fatigue claim earns its keep — mornings that start easier, an afternoon dip that isn't a cliff edge, and a steadier head through the day.

BEYOND WEEK 4

Your New Normal

Sustained results with continued daily use. Most people don't stop — because evenings that switch off properly become the standard they won't go back from.

Take 1 Magnesium Glycinate capsule daily, ideally an hour before bed. Give your body time to build a consistent routine — Week 4+ is where the difference can feel more familiar.

Serving Size: 1 Capsule. Servings Per Container: 60. All EU/UK-authorised health claims comply with Regulation (EC) No 1924/2006. A food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle.

Claims That Had to Pass a Regulator

Most sleep and calm supplements lean on words nobody has had to prove. Magnesium doesn't need to. Its benefits — reduced tiredness and fatigue, normal muscle function, normal nervous system function, normal psychological function — are EU/UK-authorised claims that passed the European Food Safety Authority's scientific review. We pair that with a high-absorption form rather than the cheap oxide most brands use, because the form decides how much actually reaches you. No borrowed credibility, no sedatives, no hype.

HOW TO USE IT

One Capsule, an Hour Before Bed. Give It Four Weeks.

1

Take

One capsule with water about an hour before you plan to sleep.

2

Be Consistent

Every night, same time. Magnesium is about replenishing levels, not a one-off knockout.

3

Give It Time

Many people feel calmer evenings within days, but give it a full 4 weeks — repletion is cumulative.

💡

If your evenings are the problem, don't take it in the morning. The people who get the most from magnesium are the ones who make it the last thing they do before winding down.

I've struggled with a busy mind at bedtime for years. Started taking this about six weeks ago and I genuinely fall asleep faster now. It's become part of my evening routine.

Elaine.M
Elaine.M Verified

I was waking up at 3am every night, mind racing. A friend suggested magnesium glycinate and I'm so glad I tried this one. Much calmer nights now.

Fiona.R
Fiona.R Verified

Takes a couple of weeks to kick in but once it does, the difference is noticeable. I feel less tense in my shoulders and I'm sleeping through more often.

Alison.W
Alison.W Verified

I work long hours and the mental fatigue was really getting to me. This has made my evenings feel more restful and I wake up feeling less drained.

Deborah.K
Deborah.K Verified

I've tried cheaper magnesium supplements before and they did nothing. The glycinate form seems to actually absorb properly. Calmer, better sleep, less muscle aching.

Lesley.H
Lesley.H Verified

My GP mentioned magnesium for my muscle cramps. Found this after some research and it's been brilliant. Cramps have almost completely gone and I sleep better too.

Tracey.N
Tracey.N Verified

Going through perimenopause and the anxiety and broken sleep were exhausting me. This has taken the edge off noticeably. I feel more like myself again.

Joanne.P
Joanne.P Verified

I take one capsule about an hour before bed. My mind winds down so much more easily now. Honestly didn't expect it to work this well.

Beverley.A
Beverley.A Verified

I was sceptical — I always am with supplements. But after a month I realised I was waking up less in the night and feeling less stiff in the mornings. Reordered

Nicole.F
Nicole.F Verified

The mental fatigue from juggling work and kids was relentless. This doesn't fix everything but it genuinely takes the edge off. I feel calmer and less overwhelmed.

Lorraine.S
Lorraine.S Verified

Second bottle now. Sleep is deeper, I'm less irritable, and the tension I used to carry in my neck and shoulders has eased. Really pleased with this.

Denise.T
Denise.T Verified

I was a bit unsure about the capsule size but it's fine with water. Noticed a real difference in how quickly I wind down after a stressful day. Good product.

Kathryn.B
Kathryn.B Verified

I do a lot of research before buying anything. The glycinate form is well absorbed and this brand is transparent about dosage. It works. Calmer evenings, better sleep.

Moira.L
Moira.L Verified

My sleep had been terrible for two years. I'm not saying this is a miracle but it has genuinely helped me fall asleep and stay asleep longer. Very happy.

Geraldine.O
Geraldine.O Verified

I take this alongside my evening wind-down routine and it really does help quiet my thoughts. Less muscle tension too, which I wasn't expecting.

Anthea.J
Anthea.J Verified

I've recommended this to three friends already. The difference in my sleep quality after just a few weeks was enough to convince me. Brilliant product.

Celia.D
Celia.D Verified

Perimenopausal sleep issues are no joke. This has been one of the few things that's actually helped. I fall asleep more easily and wake up feeling more rested.

Irene.V
Irene.V Verified

The mental fatigue was the thing that surprised me most — I didn't realise how depleted I felt until I started feeling better. This has made a real difference.

Rowena.G
Rowena.G Verified

Easy on the stomach, which I was worried about. I take it with my evening meal and sleep much better for it. Will keep buying.

Philippa,E
Philippa,E Verified

I was waking up exhausted despite a full night's sleep. After about three weeks on this I started waking up actually feeling rested. Didn't expect it to work so quickly.

FREQUENTLY ASKED QUESTIONS

Questions About Magnesium — Answered Honestly.

  • Because most of it is magnesium oxide — the cheapest form to manufacture and one of the poorest absorbed, so a large share of what you swallow never reaches you. We use a high-absorption form instead. You're paying for what your body can actually use.

  • No. Magnesium isn't a sedative and won't force you unconscious. It supports normal nervous system and psychological function, which is why evenings tend to feel calmer — without the grogginess or the foggy morning.

  • Many people notice calmer evenings within the first few nights. The fatigue benefit builds over a few weeks, because magnesium repletion is cumulative. Give it a full 4 weeks.

  • One capsule with water about an hour before bed. Same time every night.

  • Generally yes — magnesium pairs well with a normal routine. If you take prescription medication, are pregnant or breastfeeding, check with your GP first.

  • No. It's a dietary mineral, not a sedative. You can stop any time without a rebound.

  • In a GMP-certified facility. UK-dispatched.

  • Yes — 60 days, no questions asked. If your evenings and mornings don't feel different, contact us for a full refund, empty bottle or not.
