Explore the science

When will I notice results?

Many people notice improvements in bloating and digestive comfort within the first 7 days of daily use. Because everyone’s gut microbiome is different, results can vary, with some people noticing more significant improvements after 2–4 weeks of consistent use.

How do I take GutSupp daily?

Simply mix one sachet daily into hot or cold drinks, yoghurt or food. GutSupp is tasteless, easy to dissolve and designed to fit seamlessly into your everyday routine.

How much is shipping?

Free UK delivery on subscription orders. £3.50 for delivery on single purchase orders. Orders are typically dispatched within 24 hours.

Product Benefits

Supports digestive comfort and regularity by nourishing beneficial gut bacteria, helping to restore balance in the gut. A healthier gut may also support better sleep through the gut-brain connection, strengthen immune function, and contribute to improved daily energy and overall wellbeing.

What makes GutSupp different?

GutSupp is backed by over 100 scientific publications and 20+ human trials, making it one of the most studied prebiotics of its kind. It works quickly, increasing beneficial gut bacteria in as little as 7 days, while selectively feeding the bacteria your gut actually needs - not everything indiscriminately. Plus, it’s effortless to use, with a tasteless, heat-stable formula that fits easily into your daily routine.

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!

they are great

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. I went out the next day to look for some, when i got home i started straight away. After the first week or so I noticed how much better my sleep was. I have been taking gutsupp for years now and would not be without it. Ive had sleeping problems for many years and one night/early morning i saw a program on television which included someone...

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.

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.

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.

Subscription plans start at £17.99 per month with the six-month supply, billed at £107.99 every six months. Every subscription includes free tracked UK delivery and the digital Gut Health Guide. The plan selector shows the price and delivery interval for each option.

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.
