Digestive Comfort Study

WHAT WERE THE RESULTS?

A human intervention study in adults from the general population experiencing bloating, abdominal pain and flatulence found that daily supplementation with B-GOS led to statistically significant reductions in these symptoms within 7 days, with further improvements maintained into week two.

  • Conducted in adults with real-world digestive discomfort (not clinical IBS only)
  • Significant reductions in bloating, flatulence and abdominal pain scores
  • Improvements observed within 1 week, sustained at 2 weeks
  • No significant changes in stool frequency — suggesting targeted symptom relief rather than laxative effect
  • Placebo-controlled design

 https://pubmed.ncbi.nlm.nih.gov/30109908/

Reduced bloating and abdominal discomfort

Improvements observed within 7 days

What it means for you / benefits

You’re likely to feel a difference relatively quickly — particularly less bloating and discomfort — without harsh or disruptive effects on digestion.

IBS Digestive Symptoms

WHAT WERE THE RESULTS?

A randomised, placebo-controlled clinical trial in individuals with IBS showed that daily supplementation with trans-galactooligosaccharide significantly increased levels of beneficial bifidobacteria and improved key symptoms including bloating, flatulence and stool consistency, particularly at a 3.5g daily dose.

  • Conducted in IBS-diagnosed patients (higher symptom severity)
  • Dose-dependent effect, with strongest results at ~3.5g/day
  • Significant improvements in:
  • Bloating
  • Flatulence
  • Stool consistency
  • Demonstrated direct link between microbiome changes and symptom relief
  • Randomised, placebo-controlled design

https://pubmed.ncbi.nlm.nih.gov/19053980/

Increases beneficial bifidobacteria levels

Supports healthier microbiome balance

What it means for you / benefits

If it works in more sensitive, IBS-type guts, it’s strong evidence it can help with everyday bloating and digestive discomfort.

Gut Microbiome Study

WHAT WERE THE RESULTS?

A randomised, double-blind, placebo-controlled crossover study in healthy adults demonstrated that B-GOS acts as a selective prebiotic, significantly increasing populations of bifidobacteria without stimulating less desirable bacterial groups.

  • Crossover design (participants act as their own control → stronger data)
  • Selective stimulation of bifidobacteria (key beneficial species)
  • No broad overgrowth of other bacteria → targeted microbiome effect
  • Conducted in healthy adults, showing baseline gut improvement
  • Establishes mechanism of action, not just outcome

https://pubmed.ncbi.nlm.nih.gov/18326619/

Effective from low daily doses

Easy to integrate into routines

What it means for you / benefits

Rather than adding bacteria, it feeds the right ones already in your gut — helping restore balance naturally.

Metabolic Health Study

WHAT WERE THE RESULTS?

A 12-week randomised, double-blind, placebo-controlled crossover study in 45 overweight adults found that B-GOS increased bifidobacteria and led to improvements in markers including C-reactive protein (CRP), insulin levels, total cholesterol and triglycerides.

  • 12-week duration (longer-term intervention)
  • Participants had elevated metabolic risk factors
  • Observed reductions in:
  • CRP (inflammation marker)
  • Insulin
  • Total cholesterol
  • Triglycerides
  • Increased bifidobacteria linked to these changes
  • Suggests gut-driven systemic effects

https://pubmed.ncbi.nlm.nih.gov/23303873/

Supports healthy gut-brain communication

Studied alongside stress-response markers

What it means for you / benefits

Shows gut health doesn’t just affect digestion — it can influence broader health markers linked to inflammation and metabolism.

Digestive Resilience Study

WHAT WERE THE RESULTS?

A randomised, double-blind, placebo-controlled study in 159 travellers found that those taking B-GOS experienced lower incidence and shorter duration of travellers’ diarrhoea, alongside reduced abdominal pain and better overall wellbeing.

  • Large sample size (n=159)
  • Real-world high-stress gut environment (travel)
  • Reduced:
  • Diarrhoea incidence
  • Duration of symptoms
  • Abdominal pain
  • Improved quality-of-life scores

https://pubmed.ncbi.nlm.nih.gov/19756029/

Supports balanced immune responses

Encourages beneficial gut bacteria growth

What it means for you / benefits

Supports gut resilience under stress — useful beyond travel (diet changes, alcohol, busy routines).

Travel Gut Protection Study

WHAT WERE THE RESULTS?

A follow-up randomised, placebo-controlled study showed that B-GOS reduced the likelihood of diarrhoea episodes, with protective effects becoming apparent after approximately one week of consistent supplementation.

  • Reinforces time-dependent effect
  • Protection strongest with high compliance
  • Focus on short-duration diarrhoea reduction
  • Complements earlier travel study

https://pubmed.ncbi.nlm.nih.gov/28931149/

Supported by human clinical trials

Backed by decades of research

What it means for you / benefits

This isn’t a quick fix - it works by building your gut’s resilience over time.

Gut improvement obvious on day 9

I'm on day 9 of my first purchase of GutSupp. Impressed so far. I'm a really restless sleeper and wake several times a night but my sleep has improved significantly since starting the supplement. I am also someone who suffers from constipation and have had no problems at all since starting GutSupp. My internal plumbing has been working perfectly!

Ive had sleeping problems for many years and one night/early morning i saw a program on television which included someone taking gutsupp. I also was having problems with my stomach.

Perhaps a little less stress

My husband thinks I'm a little brighter. It has been a very busy month and there have been difficult situations and conversations. I have felt more calm, even and happy emotionally. I've not had a cold (the kids and husband had several) and that's quite usual for me too. I've been more 'zen' through it all. My husband thinks I'm a little brighter.

Definitely a keeper

The effects of the product itself are outstanding. I feel more energised, experience an overall better mood and wake up early and refreshed. After trying all sorts of vitamins and supplements over the years, a prebiotic like this one is definitely going to remain part of the daily routine.

Everything you need to know before starting GutSupp

Learn how GutSupp works, what to expect and why thousands take it daily for digestive comfort and gut balance.

Many people begin noticing improvements in digestive comfort, bloating and overall gut balance within the first 7 days of daily use. Clinical studies on Bimuno® GOS have shown increases in beneficial gut bacteria within this timeframe.

Because everyone’s gut microbiome is different, results can vary. Some people notice changes sooner, while others experience more noticeable improvements with continued daily use over 2–4 weeks. For best results, GutSupp should be taken consistently every day.

GutSupp is powdered by Bimuno that contains GOS. Galactooligosaccharides (GOS) are a high fibre prebiotic derived from lactose and is proven to stimulate the growth of good bacteria in your gut.

Gutsupp is derived from lactose (milk) so it is suitable for vegetarians and is also gluten-free. Gutsupp is informed sport certified so it is also suitable for athletes.

It would be a pleasure to answer any questions or queries you might have. Please feel free to reach out to hello@gutsupp.com.

Prebiotics work much like fertilisers in the garden and feed the "good bacteria" in our gut. Therefore, introducing prebiotics and probiotics into your daily lifestyle can stimulate your overall gut health and well-being. Bimuno and all food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

GutSupp is a prebiotic fibre powder that has been scientifically proven to feed & stimulate the growth of beneficial bifidobacteria in your gut within just 7 days. Helping to promote optimal gut health and further whole body benefits.

Gutsupp is a prebiotic. Prebiotics can be thought of as the food for the 'good types of
bacteria in your gut such as bifidobacteria that help balance your microbiome.
Probiotics are 'live' bacteria. The issue with many probiotic supplements is that they
don't reach your gut intact and if they do, lack the food they need to thrive and be
effective.

For best results Gutsupp should be taken daily. In the first 7 days, you might notice
some slight tummy gurgling, a positive sign that your gut microbiome is starting to reset.
It's very important that you continue to feed the good bacteria in your gut.

GutSupp is a tasteless powder that dissolves easily on food or in drink. Simply add to
your morning hot drink or juice, or add to your porridge or yoghurt bowl.

GutSupp can be bought from as little as 59p a day with free UK delivery.

Yes, Gutsupp can help your symptoms of IBS! If you have a particularly sensitive stomach we recommend taking a ½ sachet for the first 7-10 days to let your gut gradually transition.

Yes you can! Gutsupp transitions through the gut to the large intestine (colon) and is
not absorbed to other areas of your body.
