You didn't notice it working. That was the point.
Probiotics have an unusual feedback loop.
Some notice a big difference. Others don't notice much.
For probiotics, you feel the absence of the problem they were preventing - the digestion that stays strong during a work trip, the week that stays steady despite late dinners or disrupted sleep.
When things become steady, it's easy to conclude nothing is happening.
That steadiness is not a signal to stop. It means the input is doing exactly what it should.
Most people stop at 30 days. Not because it isn't working. Because it's working exactly as it should - and they don't recognise it.
Your microbiome doesn't hold its position.
Your gut is not a switch. It is an ecosystem.
Ecosystems stabilise through repeated inputs, not single interventions.
The strains you introduce don't stay permanently. It’s like eating yoghurt, kimchi or sauerkraut every day - except those sources don't guarantee named strains at validated doses.
When you stop the input, the environment shifts back. Not overnight. Not dramatically. But the digestive consistency you'd built just quietly fades. The heaviness after a late dinner comes back. The unpredictability on travel days returns.
A steady baseline you'd started to forget.
This is called microbial drift. It's biology.
THE TIMELINE LOGIC
30 days introduces. 90 days integrates.
*Individual results vary. Food supplements don't replace a varied, balanced diet and a healthy lifestyle.
Most probiotic products compete on volume. We compete on evidence.
The industry competes on strain count - 5, 10, 20+ strains, 50 billion CFU. These are marketing numbers.
Your gut doesn't work that way.
LGG® and BB-12® are two of the most clinically documented probiotic strains in published literature. We chose them, not because they were easy to source, but because the science is traceable: published, peer-reviewed, and strain-specific - not a "blend" you can't independently verify.
10 billion CFU per sachet. Guaranteed until end of shelf life - not just at manufacture.
Precision strains. Without a bacteria's "strain name," any science claims don't apply.*
Taxonomy: Genus > Species > Subspecies > Strain. For Gutcultured®, the registered strains are Lacticaseibacillus rhamnosus GG, LGG® and Bifidobacterium animalis subsp. lactis BB-12®.
One sachet. Same time each day. That's the whole ritual.
Freeze-dried for stability. No refrigeration required - the same potency whether it's in your kitchen cabinet, your carry-on, or your desk drawer.
Dissolves in any drink or can be taken directly on your tongue. No taste that requires masking.
No timing requirements around food.
Consistency matters more than perfect timing. Take it when it fits your day, and, keep taking it.
Try it properly. If nothing shifts, we'll refund your first month.
When people stop because they didn't see results, they often never gave it a fair evaluation - inconsistent use, wrong expectations, no baseline to measure against.
This guarantee is built around fixing that.
When you start your 90-day routine, we send you four short check-ins at day 14, 30, 60, and 90. Under 3 minutes each. They're not surveys for our benefit. They're a structured way for you to track what's actually changing - because with probiotics, the shifts are quieter than you'd expect and easy to miss without a reference point.
Complete at least three of the four check-ins. If you reach day 90 and honestly don't observe a meaningful difference in your digestive baseline, contact us. We'll refund your first month. No return. No additional paperwork beyond the check-ins you've already completed.
What that means in practice:
- For the standard price Rebalance 3-month pack: €54.50 back.
- For the standard price Lifestyle Subscription: €49.50 back.
One thing worth saying plainly:
This is a partial refund, not a full one. We're honest about that because the science is also honest. 90 days of consistent daily use produces a measurable shift for most people. We're not promising a dramatic result. We're committing to the process, and protecting your first month if it doesn't deliver.
We're not asking for blind trust. We're asking for 90 days, honest check-ins, and your own judgement.
*Note: Applies to the Rebalance 3-month pack and Lifestyle Subscription. The one-month purchase is not covered. At least 3 of 4 check-ins must be completed within 7 days of each prompt to qualify. Check-ins are sent by email. If you don't receive one, contact us.
What you get with the 90-day routine:
- 90 sachets. LGG® + BB-12®. 10 billion CFU guaranteed per sachet.
- Two of the most clinically documented probiotic strains in published literature.
- Four structured check-ins to track what's changing.
- Free EU delivery.
- First month guaranteed under the 90-Day Confidence Guarantee.

Your questions, answered.
Because clinically-proven should also be clear-cut.
What makes BB-12® and LGG® better than generic live cultures?
The difference is traceability. LGG® and BB-12® are registered, named strains with published, peer-reviewed research tied specifically to those strains - not a generic blend where the science from one strain is claimed for another.
Remember, without the strain name, any science claims don't apply.*
*Taxonomy:
Genus > Species > Subspecies > Strain
For Gutcultured®, the registered strains are Lacticaseibacillus rhamnosus GG, LGG® and Bifidobacterium animalis subsp. lactis BB-12®.
Why only two strains? Isn’t more better?
Not always. Many multi-strain formulas include unproven bacteria. We selected the two most researched strains with synergistic effects - simplifying without sacrificing efficacy.
Does BB-12® and LGG® support the gut-brain axis?
Gutcultured® is researched and sold for gut barrier support and digestive regularity - these are the clinically validated areas for LGG® and BB-12®.
The gut-brain axis is an area of ongoing research where researchers study the link between gut barrier integrity, microbiome composition, and neurological signalling.
What we can safely say is that the strains in Gutcultured® - LGG® and BB-12® - are among those cited in that research. The gut is where we work and we know our strains are outstanding for gut barrier support and digestive regularity. What happens upstream is what the science is continuing to investigate.
How long does it take for a probiotic to work?
Clinical research points to 90 days as enough time for meaningful, measurable change in the gut environment.
LGG® and BB-12® studies use 30–90 day protocols. The 30-day mark introduces the strains. The 90-day mark is where the research documents a stable shift in the digestive baseline.
Can I take Gutcultured® with antibiotics?
Yes. LGG® was selected specifically for its ability to survive antibiotic exposure. It's been used safely alongside antibiotics in hospital settings for over 30 years.
Is this safe during pregnancy or breastfeeding?
Yes. Both BB-12® and LGG® have been safely studied in infants, children, and pregnant women. However, always consult your healthcare provider.
Can I travel with it?
Yes. Our sachets are shelf-stable for 24 months, no refrigeration needed.
