Clinically Proven Live Bacteria

Calmer, more predictable digestion, day after day.

Two of the world’s most studied probiotic strains - LGG® + BB-12® - designed to support regularity,¹ digestive comfort,²⁰ and balanced microbiome.¹³

*Built for daily use, because the microbiome adapts gradually - not overnight.

Try Gutcultured Today

Clinically Proven.
Expertly Crafted.
Trusted Worldwide.

Every batch meets the world’s strictest standards for safety, stability and efficacy. Tested, certified and manufactured in Denmark.

Real change takes consistency.

Here’s what a 3-month journey can look like.

The microbiome adapts gradually.
A daily, consistent routine over 90 days allows your gut ecosystem the time it needs to adjust and stabilise.

Month 1: Foundation & Adaptation

Your microbiome begins adjusting to daily use.
Some people notice early digestive changes.
For others, this phase feels subtle.

This month is about establishing a stable baseline.

Month 2: Stabilisation & Digestive Ease

With continued daily use, digestion often begins to feel more predictable.

Some people describe:
• Greater regularity
• More consistent days
• Fewer fluctuations

This is where routine starts to compound.

Month 3: Deeper Balance & more Stable Microbiome

After 90 days of daily use, your microbiome has had time to adapt.

At this stage, most people feel ready to properly evaluate their routine.

Beyond 3 Months: Sustained Microbiome Health

Probiotics are not a quick fix.
They work best when taken consistently.

Because strains do not permanently colonise the gut, continued use maintains exposure.

Best results are seen alongside healthy lifestyle habits.

CONSISTENCY LOOKS GOOD ON EVERYONE

You’ve seen it in their routines. Now make it part of yours.

Meet the strains

Two world-leading bacterial strains. Clinically documented in over 500 human studies and 2,500 scientific publications worldwide - the most researched live cultures strains on earth.

Up to

70%

Decrease risk of antibiotic-associated gut issues

Up to

50%

Reduced risk of eczema and atopic dermatitis⁴

Up to

50%

Shorter duration of diarrhea, including antibiotic-associated diarrhea ² ³

Lacticaseibacillus rhamnosus, LLG®

The world's most documented bacterial strain - trusted for immune, gut, and barrier support.

• Strengthens the intestinal barrier and reduces gut "leakiness", so irritants are less likely to cross into the bloodstream. ¹ ³

• Helps protect gut and immune balance during stress, travel and antibiotic use. ⁷ ¹³

• Studied across all life stages, from infants to adults. Safe for pregnant women and breastfeeding mothers.

Bifidobacterium animalis subsp. lactic, BB-12®

Clinically validated for digestive comfort and immune balance.

• Supports gut barrier integrity and strengthens natural immune defenses.

• Stimulates serotonin secretion in the gut, which helps regulate key functions like gut motility and nutrient absorption.

• Supports a balanced gut microbiota by crowding out unwanted bacteria, and produces anti-microbial substances.

How we compare

Not all live cultures are created equal. Gutcultured isn’t just “science-backed”, we’re clinically proven.

Feature Gutcultured Other Supplements Functional Drinks with "Probiotics"
Clinical Documentation Backed by published clinical studies on named strains Often generic, not strain-specific Rarely supported by clinical trials
Strain Identification Uses well-documented, clinically-researched, and most importantly, "named" bacterial strains (LGG® and BB-12®) May list species only, without specifying strains or linked research May list species, without specifying strains or linked research
Potency Guarantee Guaranteed viable count until end of shelf life Often labeled “at manufacture” only or not at all Potency not usually guaranteed at consumption
Regulatory/Quality Status Includes strains with QPS (Qualified Presumption of Safety) and GRAS recognition Varies - not always QPS or GRAS confirmed Not typically QPS or GRAS recognized
Survivability Documented acid and bile tolerance; survivability demonstrated in studies Survivability varies, not always tested Live bacteria often unstable during processing or storage
Shelf Life / Stability Stable under standard storage conditions Stability not always validated Requires refrigeration; bacteria may decline before consumption

Why we built Gutcultured

A new era of gut care, built for modern life, proven by decades of clinical research.

Your gut under pressure

The impact of modern life on your microbiome

Processed food, stress, poor sleep, travel and antibiotics can all place strain on your gut microbiome. When the gut barrier weakens, researchers describe a process they call increased intestinal permeability, in everyday language a "leaky gut", which clinical research links to low-grade inflammation in the body.²¹

In daily life, gut imbalance often shows up as bloating, irregular digestion, sensitive skin, and feeling more run-down. Scientists are also studying the gut-brain axis: the continuous, two-way communication between the microbiome, the immune system, and the brain.²²

Research from UZ Leuven and the Rome Foundation found that up to 40 per cent of people worldwide, and 38 per cent of adults in Belgium, meet the criteria for a disorder of gut-brain interaction (DGBI), such as bloating, constipation or irritable bowel syndrome,²³ demonstrating how a healthy microbiome is harder than ever to maintain.

For us, that figure is not just a statistic. Our founders watched people close to them move through the same cycle of bloating, irregular digestion and low resilience, before seeing what a supported microbiome and a simple, clinically backed daily routine could do. That journey became Gutcultured.

Our Philosophy

Genes matter, but only 20%. The rest? Your lifestyle.

In health, the latest science confirms that genes matter - but only 20%. The rest? Your choices. Your gut sits in the center of the 80% you control - sleep, nutrition, movement, stress, recovery, connection, purpose.

Gutcultured sits inside this bigger lifestyle philosophy - not as a magic pill, but as a precision tool that reinforces your daily choices.

Your questions, answered.

Because clinically-proven should also be clear-cut.

What makes BB-12® and LGG® better than generic live cultures?

They’re not just names - they’re clinically documented strains, backed by 500+ clinical studies and 2000+ scientific publications, and recognized by regulatory authorities like EFSA and FDA. Many products use unverified, non-traceable blends.

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.

Is it safe to take daily?

Absolutely. Our strains have Qualified Presumption of Safety (QPS) status in the EU and GRAS status in the US. Daily use is not only safe - it’s where the benefits compound.

What results should I expect, and when?

Most people feel lighter and more regular with consistent use over 4 weeks.

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 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.

Can I travel with it?

Yes. Our sachets are shelf-stable for 24 months, no refrigeration needed.
