Why does your stomach bloat even when you eat well?

You eat well. You're careful. And your belly bloats anyway.

It's not a lack of willpower. It's not your diet. It's not even your digestion.

It's your nervous system.

When stress sets in (work, mental load, accumulated fatigue, screens), your body produces cortisol continuously. And when cortisol stays high, everything goes out of balance:

Digestion slows down — your body switches to survival mode, not digestion mode

Acidity rises — heartburn, reflux, discomfort after every meal

The stomach tenses up — tension, gas, blocked stomach

The body retains water — bloated stomach, puffy face, heavy figure

The microbiota becomes unbalanced — even probiotics can no longer compensate

You've probably tried herbal teas, probiotic courses, gluten-free or lactose-free diets. And nothing changed in the long run.

Because you were treating the symptom. Not the cause.

The cause is a nervous system under tension that prevents your body from functioning normally. As long as stress doesn't go down, the stomach can't relax.

When stress goes down, the belly follows. That's exactly what Brainstoorm was designed for: to soothe first, so that your body regains its balance.

Does this concern you? Check below.

This concerns you if you recognise at least 3 of these signs...

Now, count:

Your stomach is flat in the morning… but bloated by the afternoon

You eat a balanced diet, but the bloating comes back anyway

You exercise regularly, but your stomach stays bloated all the same

After meals, your stomach becomes hard, heavy or uncomfortable

You regularly have gas, abdominal pressure or that feeling of a blocked stomach

Some mornings, your face looks puffy (water retention, inflammation, fatigue)

Stress settles straight into your stomach and your body

Coffee makes you jittery, gives you acidity or worsens the bloating

You’re looking for a hot drink that truly respects your digestion

You’ve tried probiotics, herbal teas or diets with no lasting result

You avoid certain clothes because of your stomach

You feel tired the moment you wake up, even after a full night’s sleep

Your digestion depends on your stress level — the more tense you are, the more it blocks up

3 signs or more? Your gut isn’t the problem. It’s your nervous system running in overdrive. And that’s exactly what Brainstoorm targets.

The next question you’re asking yourself: ‘OK, but how long until it changes?’

Day 1, Day 7, Day 30: what to expect in concrete terms?

☕ DAY 1 — From the very first cup

Your stomach stays flat after your cup

No acidity, no surge of stress

A warm, comforting moment, with no downside for your stomach

You won't be waiting 3 months to feel something. Here's what our customers describe:

🌿 DAY 7 — The body starts to let go

• Less bloating as the day goes on
• Smoother digestion, less gas, less of a hard belly
• Your body relaxes — you feel lighter

🌬️ DAY 21 — Balance sets in

• A more stable belly, even after meals
• Less retention and swelling (belly + face)
• A calmer mood, more consistent well-being

✨ DAY 30 — The transformation

• You no longer think about your belly before getting dressed
• A less puffy face in the morning, a body that retains less water
• You look at yourself differently in the mirror — your glow comes back naturally
• Stress drops, you're calmer and more aligned in your body

🔄 AFTER 30 DAYS — When the adaptogens really take over

30 days is the moment you feel the difference. But that's not where the real work stops. Adaptogens don't mask anything. They retrain your body to work differently.

At 60 days:

• Cortisol regulates deeply — your body no longer overreacts to the slightest stress
• The microbiome strengthens — digestion becomes naturally smooth, without thinking about it
• Energy stabilises throughout the day — no more morning spike followed by the crash

At 90 days:

• A flat belly is no longer a good day — it's your new normal
• Clearer skin, de-puffed features, your radiance back
• What used to send you over the edge no longer affects you the same way
• The people around you start noticing the change before you do

Adaptogens work like training: in the first few weeks, your body learns. After 2-3 months, it has integrated the new reflexes. The result is no longer an effort — it's a state.

That's why the women who stay beyond the first month never go back.

Curious to know what's inside to get all this? Here's the formula.

The 9 active compounds behind the flat-belly effect (and why they work together)

You’ve just seen the results. Here’s how we get there.

Each ingredient was selected to act on one of the 3 levers you discovered above: calming the nervous system, soothing the gut, restoring balance.

🌿 Acacia — 2708 mg

The digestive pillar. A gentle prebiotic fibre that nourishes the microbiota and promotes comfortable transit. Reduces bloating, gas and the feeling of a blocked belly. It's the one that gets the work going from Day 1.

🍄 Chaga — 1000 mg

The anti-inflammatory. A powerful antioxidant that calms the low-grade inflammation responsible for swelling. Supports cortisol regulation — the key ally for sensitive bellies.

🌿 Ashwagandha — 200 mg

The cortisol regulator. Helps your body come out of alert mode. Less cortisol = less tension in the gut, less retention, less tightness.

🍄 Lion's Mane — 1000 mg

The gut–brain bridge. Acts on the gut-brain axis to reduce mental overload and stop stress from settling in the gut. Also supports focus and memory.

🌱 Maca — 3000 mg

Hormonal balance. An adaptogenic plant that helps the body better cope with everyday stress. Also boosts natural energy and libido — a relaxed body is a body that regains its vitality.

🍄 Cordyceps — 1000 mg

Energy without overstimulation. Improves oxygenation and helps the body cope with effort and fatigue without overloading the nervous system. Stable energy, zero jitters.

🍫 Cocoa — 1400 mg

Pleasure with no trade-off. Rich in antioxidants, supports mood and brings an indulgent taste with no acidity. Gentle on sensitive stomachs.

🌼 Rhodiola — 25 mg

Gentle resilience. Helps the body adapt to physical and emotional stress, without overstimulation.

☕ Newcaff microencapsulated caffeine — 20 mg

The smart boost. Gentle, gradual stimulation. No sharp spike, no crash, no jitters that end up in your stomach.

Also contains xylitol and vitamin B5 to support cellular energy.

🔑 The principle: helping your body relax before trying to perform. It's this approach that makes the formula different from anything else out there.

And compared with other brands? Spoiler: nobody doses like this.

6225 mg per cup: why other brands can't keep up

You know the formula. Now, here's why it's unbeatable.

6225 mg of active ingredients and adaptogens per cup — 3x more than other brands on the market

240 g per jar (vs 180 g for the competition) — better dosed, more effective

5x less caffeine than a regular coffee — energy without jitters, without a crash

11.84 kcal per cup — zero sugar, zero fat, zero additives

100% clean — vegan, GMO-free, gluten-free, lactose-free

Up to 2x cheaper than other brands — with more benefits

Delicious choco-hazelnut coffee flavour — no mushroom taste

A real, lasting effect on energy, digestion and stress. Not a placebo — the most complete formula on the French market.

Excellent for cutting down on coffee and quitting it

If, like me, you want to cut down on your coffee consumption without losing energy or performance, I’ve found an excellent alternative. No jitters, no bloating, and with a real reduction in stress and anxiety. Ideal if you want to cut down on your coffee consumption without losing effectiveness.

A wonderful discovery

I feel much less bloated after drinking it, digestion is lighter and more comfortable, with no feeling of heaviness. On top of the indulgent taste (special mention for the chocolate note ), it gives me gentle energy, with no jitters. A real favourite for combining pleasure, digestive well-being and a daily boost

My gut is calmed

From the very first dose, I noticed relief in my digestion, my stomach was less heavy, less bloated, no more slump after my meal. My bowel movements became normal again. I’m continuing the experience!

Good vitality

I felt the benefits from the very first day. A very pleasant vitality, good digestion and I’m less hungry in the morning, I no longer get the famous ‘sugar spike’ and I sleep better. The taste is very pleasant; the first time it surprises you because it’s not like other breakfast products, but by the second time I’d adopted it!.

Fast delivery

Fast delivery. A real difference in flavour compared to other similar drinks. A very good alternative to coffee. The cocoa flavour means less sugar and allows easier digestion. No more weight on the stomach at the end of a meal. Got it right with the first pack 👌🏻

Won over

A fast, careful delivery and a wonderful discovery! I came across Brainstoorm and I admit I was rather sceptical, having already tried this kind of alternative before. But this one clearly stands out. Pleasantly surprised by its mild taste of coffee, chocolate and hazelnut: it’s both indulgent and comforting. Perfect for a gentle wake-up, just the way I like it, but also for cocooning and warming up over an afternoon snack. Having already tried other brands based on mushroom extracts, I can say that, to my taste, this one is by far the best: no bitterness or unpleasant aftertaste. It has finally let me find a real coffee alternative that I truly enjoy. I felt more stable energy, reduced stress, less bloating and a real overall sense of well-being, with improved digestion. I also really appreciate that it’s gluten-free, lactose-free, with no added sugar and no additives.

I started testing the super coffee...

I started trying MushNGo's Super Café Brainstoorm recently, and honestly, I loved discovering it. The taste is really pleasant, fairly mild, with a slight chocolate and hazelnut note, without the bitterness you can find in some coffees. The difference shows above all in the energy: it's much more steady, with no sharp surge, no jitters or palpitations, and especially without the famous slump afterwards. I feel more focused, calmer, and my digestion is easier too. The blend of adaptogenic mushrooms and plants is a real plus, and the fact that the caffeine is lower suits me much better. It's clearly an alternative to regular coffee that I now include in my daily routine.

Coffee alternative

I tried the chocolate/hazelnut flavour, a taste that is good and clearly noticeable. Just take 2 spoonfuls of Brainstoorm then add 200 ml of hot or cold water or milk, and that’s it! It’s the coffee to try for people looking for a drink with no jitters, with flavour, better energy and better focus, while avoiding stress and digestion problems.

A lovely discovery

A lovely discovery With my sensitive stomach, coffee was something I had to strictly limit. But THIS coffee (chocolate hazelnut for me) reconciled me with cups of coffee whenever I fancy one. No more digestion pain and above all, I no longer feel the harmful effects (jitters...). I highly recommend it

Delicious and effective super coffee

This coffee alternative, based on adaptogenic mushrooms, is healthy and lets you treat yourself while regaining your energy throughout the day. You can make your coffee very easily and quickly by simply adding the product to water or milk. The chocolate hazelnut flavour is delicious, I love making it in hot milk with a dash of hazelnut syrup. I noticed I was much more productive after having the Brainstoorm super coffee, I felt far less tired than usual, and my digestion was much better than with regular coffee. I also tend to be anxious, and I saw a clear difference when having this product, I feel calmer and less stressed. It’s a versatile and delicious product that I recommend!
