Something's Taken Over Your Gut

If You Get An Itchy Backside At Night, Something's Taken Over Your Gut — And It's Worse Than You Think.

Why so many men over 35 are bloated, tired after eight hours' sleep, craving sugar and itching for no reason — and the simple two-gummy habit one Dublin man says finally settled it.

The bacteria in your gut outnumber your own cells. When the wrong ones take over, they feed off everything you eat — and nobody is telling men about it.

Gut out of balance vs healthy gut
Left: a gut out of balance. Right: a healthy one.
Estimated 6-minute readUpdated September 2026

It started, for Mark Doyle, at about three in the morning.

The itch. Down there. The one no man mentions to anyone. It would wake him, he'd lie there, and by the time it eased the alarm was an hour away.

Seven and a half hours in bed on his watch. Feels like four.

He'd stand at the bathroom mirror and press his fingers into his cheeks. Push at the soft line under his jaw. Stick out his tongue — white again. Turn sideways. Pull his stomach in. Let it out.

Still there.

"A lad at work asked if I'd been on the beer the night before," he says. "That's how puffy and wrecked I looked. Every single morning. I hadn't had a pint since Saturday."

By afternoon it's worse. Bloated after lunch like he's swallowed a football — and it's not just gas. A wall at three o'clock that only a bar of chocolate gets him through. Skin that itches for no reason. A rundown feeling he can't shake and can't explain.

Mark is 43. An operations manager in Dublin who trains four mornings a week, eats "reasonably well" and is not the kind of man who ignores his health.

"It's not laziness," he says. "I was doing everything. I just felt like something had taken over and was running the show from the inside."

Mark at his desk at 3 PM
3:15 PM. Second coffee gone. The chocolate is being negotiated.

What Mark didn't know at the time is that he was closer to the truth than he realised. Something had taken over. Not a mystery illness. Not his age. The bacteria in his gut had gone out of balance — and they were working against him.

Do Any Of These Sound Familiar?

  • An itch "down there", worse at night, that comes and goes and you'd never mention
  • A gut that always feels bloated — and it's not just gas
  • Waking up tired even after eight hours of sleep
  • A white coating on your tongue in the morning
  • Skin that itches for no reason
  • Sugar cravings at three in the afternoon and ten at night
  • A stubborn belly that doesn't respond to training the way it used to
  • That rundown, foggy feeling you can't shake
Three or more?Most men treat these as separate problems. A cream for the itch. A fat burner for the belly. A fourth coffee for the crash. Something for the tongue, if they mention it at all.

What if they all trace back to the one thing nobody checked — the trillions of bacteria living in your gut?
Balanced gut vs gut out of balance
The more sugar you feed it, the more it makes you crave.

The Thing Nobody Checked

Mark went to his GP twice in two years. Bloods, thyroid, iron, cholesterol, blood sugar. Everything came back normal.

The night-time itch got a sensible answer, too: threadworms are the most common cause in Ireland, a pharmacy treatment clears them in days, and it's worth ruling out.1 Mark did. It came back anyway.

"He told me I was healthy and to keep doing what I was doing," Mark says. "I was doing what I was doing. That was the problem."

GP consulting room
Everything came back normal. That's the frustrating part.

That's not a criticism of GPs. A standard blood panel is designed to catch disease, and Mark didn't have one. What nothing on a lab sheet measures is the balance of bacteria in your gut — and that balance decides a lot more about how a man feels than most men have ever been told.

What Your Gut Bacteria Actually Do

There are more bacterial cells in and on your body than human ones.2 Most of them live in your gut, and the good ones earn their keep: they help break down food, they train your immune system, and they talk to your brain along a nerve-and-chemical line researchers call the gut–brain axis.2,3

Break down food, train your immune system, talk to your brain, outnumber your own cells

Here's the part most men have never heard: the balance can tip. Feed the gut sugar, late takeaways and weeknight pints and cut its sleep short, and the harmful bacteria get the conditions they like. Your gut becomes a breeding ground for the wrong stuff — and the wrong stuff feeds off everything you eat.

Sugar and late takeaways → bad bacteria feed → bloated, tired, craving

It steals your energy. It leaves the gut sluggish and bloated. And the worst part: research shows a short night's sleep alone pushes the brain toward calorie-dense, sugary food the next day4,5 — so the more sugar you feed it, the more it makes you crave. A loop that runs itself, at 3 PM and again at 10 PM, every day.

What Happens When It's Ignored

Nothing dramatic. That's what makes it so easy to miss.

Mornings get a little puffier. The tongue stays white — a coating that Mayo Clinic links, in everyday cases, to dehydration, alcohol, a low-fibre diet and the bacteria that build up on it.6 Lunch sits heavier. The belt goes out a hole and you blame the Christmas. The 3 PM crash arrives earlier. The itch comes back on the long sitting days — sweat, moisture and diet are all on the HSE's list of common causes1 — and you'd rather live with it than say it out loud.

Fourth session of the week. Same body as last month.

And through all of it you're still training. Still turning up. Still doing the work. Which is exactly why it's so demoralising when a man who trains four days a week looks like he trains none.

"I kept blaming my workouts. Then I kept blaming my age. Neither explained why a man training four days a week looked and felt like he was training none."

Why Nothing Worked

Mark had tried the lot.

A detox tea that changed nothing except how often he visited the bathroom. A fat burner that gave him the shakes. A pre-workout that made his heart race. Six weeks of cutting carbs that ended with him eating his kids' Easter eggs at eleven at night — which, he now knows, was the loop winning.

Detox tea, fat burner, pre-workout, cutting carbs — crossed out

Every one of them attacked one symptom from the outside. None of them did anything for what was going on in his gut. And every one of them was complicated enough that he'd quit inside a fortnight — and go straight back to feeding the wrong bacteria.

"I didn't want another routine I'd fail at," he says. "I wanted one thing I'd actually do every day."

What Actually Shifts It

The lad at Mark's gym who put him onto it was in his fifties and had more energy than anyone in the place. He didn't sell it. He just said: two gummies a day, ten mushrooms, no caffeine, keeps them next to the coffee machine.

Functional mushrooms have been used daily in traditional practice across East Asia for centuries.7 What's newer is the research interest in what they do in the gut: mushroom fibres and polysaccharides are being studied as food for the good bacteria — the kind that help crowd out the bad stuff — though most of that work is still early and in the lab.8

Lion's Mane, Cordyceps, ReishiChaga, Shiitake, Maitake

Each of the ten has its own reputation — the roles men keep reading about:

Ten mushrooms. One full-spectrum blend. Two gummies. And a gut that's finally being fed something the good bacteria like.

Mark

He ordered a pouch on a Sunday night and put it beside the coffee machine so he couldn't miss it.

Mark at the kitchen counter with two Mycella gummies
Kettle on. Two gummies. Out the door.

The first thing that changed wasn't his gut. It was that he actually did it. Day three, day ten, day twenty, the pouch was there and the gummies took four seconds. For the first time in years he had a small win before 7 AM — and the rest of his day started organising itself around it. A proper lunch instead of the deli counter. Water on the desk. Phone charging in the kitchen, not the bedroom. Pints on Saturday only. The loop, starved.

"Two gummies was something I could actually remember. Once that stuck, the rest of my day started sticking too."

Five months on, the mornings look different. Gut settled. Less puffy. Belt two holes in. The 3 PM chocolate run happens rarely enough that his colleagues noticed. Tongue pink. And the thing he never mentioned to anyone? "Haven't thought about it in weeks."

What To Expect

Days 1–7Days 1–7

The habit forms. Pouch beside the coffee, two gummies, done — and the sugar the wrong bacteria were living on starts to dry up.

Weeks 2–4Weeks 2–4

The routine becomes automatic. Many men say the mornings feel different first: gut settling, less of the 3 PM negotiation.

Months 2–3Months 2–3

This is where men reorder — not because they have to, but because they don't want to go back to how the mornings felt.

Individual experiences vary. Mycella is a food supplement, not a treatment; keep training, eating and sleeping well.

Your Body Has Been Trying To Tell You Something

Another 3 AM wake-up, scratching.

Another morning puffy and foggy, tongue white.

Another afternoon dragging yourself to the vending machine to feed the thing that's feeding on you.

Or…

You sleep through. Your gut settles. Your energy comes back. Your mind clears. The shirt sits flat. And the only thing you changed was two gummies with your coffee, every single day.

The Decision Mark Almost Didn't Make

"I'd spent hundreds over three years on things that didn't work," he says. "When I saw this was under forty euro and two gummies a day, not trying it would have been the mad decision."

The bacteria in your gut don't take a day off. They eat what you give them, every day — and the men whose bodies change are the ones who finally have one thing they never skip.

Frequently Asked Questions

How quickly will I notice anything?

The habit is what changes first — most men say the mornings feel different inside the first couple of weeks once the routine sticks and the sugar loop is broken. Bodies change over months, not days, and only when the training, sleep and food line up around the ritual. Individual experiences vary.

Does Mycella kill bad bacteria or worms?

No, and be wary of anything that says it does. Mycella is a functional-mushroom food supplement. Mushroom fibres are being studied as food for the good bacteria; if you think you have threadworms, a pharmacy treatment is the right answer, and a persistent itch should be seen by your GP.

How is this different from a detox tea or a fat burner?

Those work on one symptom from the outside and are hard to stick with. Mycella is two raspberry gummies a day with ten functional mushrooms — a daily ritual designed to support focus, energy, calm, sleep and immunity, and simple enough that you don't quit it.

Does it contain caffeine or anything psychoactive?

No. No caffeine, no stimulants, no psychoactive mushrooms. Functional mushrooms only.

How do I take it?

Two gummies a day, whenever you'll actually remember. Most men anchor it to the morning coffee. Follow the directions on the label and don't exceed the recommended dose.

Is it safe with medication?

If you take any medication or have a medical condition, check with your GP or pharmacist before starting any mushroom supplement. If a symptom is persistent, severe or worrying you, see your GP — a supplement is not a substitute for that.

What's in it, exactly?

Lion's Mane, Cordyceps, Reishi, Chaga, Shiitake, Maitake, Tremella, Royal Sun, Black Fungus and White Button — 250 mg of 100% fruiting-body extract of each per two-gummy serving. Vegan, non-GMO, gluten-free, no fillers.
