About Bimuno

What is Bimuno?

Bimuno® is a prebiotic supplement containing a proprietary galactooligosaccharides (GOS) composition. Bimuno GOS is targeted to specifically feed bifidobacteria, a type of good gut bacteria. Bimuno has shown to reduce digestive discomfort, strengthen immune health, influence brain function and mood, and help protect against pathogens1,2,3,4.

Bimuno is available as a prebiotic powder: Bimuno® DAILY

Who can take Bimuno?

Bimuno can be taken by anyone (aged 4 years and over) who wishes to maintain their digestive health and general wellbeing. 

Is Bimuno suitable for children?


Bimuno® DAILY is suitable for children aged 4 years and over.

Young children should always take Bimuno under the supervision of an adult.

Bimuno® DAILY is a taste-free powder, which comes in an easy to use sachet. Pour one sachet of powder into tea, coffee, juice or other drink, or sprinkle it over food. Take one sachet daily, if you have a sensitive stomach, take half a sachet for 7-10 days and if well tolerated, increase to 1 sachet per day.

Is Bimuno a medicine?

No, Bimuno is a prebiotic food supplement that contains fibre and supports a healthy gut environment.

When should my patients take Bimuno?

Bimuno can be taken any time of the day. We recommend taking it at the same time each day so it easily becomes part of their daily routine.

How often should my patients take Bimuno?

Bimuno should be taken once a day. For optimum results, Bimuno should be taken as part of a daily routine to continue feeding good gut bacteria.

What should my patients expect when taking Bimuno for the first time?

Days 1-3: When you take Bimuno for the first time, it should take about 3 days to start feeding your good gut bacteria, specifically bifidobacteria.

Days 4-7: You may start to feel some slight gurgling in your tummy. This is a good sign as it means Bimuno is beginning to reset your gut microbiome (the bacteria in your gut).

Days 8-14 and beyond: Bimuno is feeding and nurturing your good gut bacteria. Make Bimuno part of your daily routine and continue to feed your good gut bacteria.

With daily use, the majority of Bimuno users experience an increase in their gut bifidobacteria within 7 days, although individual responses may vary.

Can Bimuno help with sleep?

The BBC programme “The Truth About Sleep” showed the impact on Dr Michael Mosley of consuming Bimuno® DAILY. The programme explained the impact of improving fibre intake and the positive effect that this has on the good bacteria in your gut and inferred that this may improve sleep patterns. In the programme Dr Michael Mosley discussed how his sleep patterns had improved whilst taking Bimuno in the evening before going to sleep. It should be noted that no formal clinical investigations have been conducted to assess the impact of Bimuno on sleep patterns.

Are there any side-effects with taking Bimuno?

In the first week of taking Bimuno, you may experience some stomach gurgling and rumbling which often subsides after a few days.

You may want to consult with your doctor or other healthcare professional before trying Bimuno if you suffer from any health problems and/or using prescription medications.

Is it safe to take Bimuno long-term?

Yes, Bimuno is designed to take long-term. We recommend you take Bimuno as part of your daily routine, in order to give your good gut bacteria a constant source of food so that it continues to thrive.

Where can my customers or patients buy Bimuno from?

In the UK, the complete Bimuno range is available online at, Boots and Amazon. Bimuno is also stocked in Holland & Barrett, Tesco, Sainsbury’s, and independent pharmacies and health food shops across the UK, however the Bimuno products they sell may vary from store to store.

Pre-existing conditions, intolerances and special diets

Can my patients take Bimuno if they are pregnant or breast feeding?

Yes, they can. Bimuno is a food supplement and not a medicine. It is not absorbed but transits through the gut to the large intestine (colon) where it feeds good gut bacteria with positive effects for their host.

Will Bimuno interfere with chronic medication?

Bimuno is a food supplement and not a medicine; to the best of our knowledge, there are no described contraindications or interactions with medicines.

Can Bimuno be taken whilst undergoing chemotherapy or radiotherapy?

Although we have not had any studies looking at the safety of Bimuno in cancer patients during or after chemotherapy and radiotherapy, the scientific evidence suggests that it is safe to take supplements like Bimuno during chemotherapy and radiotherapy.

Bimuno is a food supplement and not a medicine; to the best of our knowledge, there are no described contraindications or interactions with medicines.

Is Bimuno suitable to take if my patients have a pre-existing medical condition such Coeliac Disease, SIBO, IBD etc.?

Bimuno is generally regarded as safe to take even if you have existing medical conditions.

We identify allergens in bold in our ingredients list on each pack.

Is Bimuno suitable for people suffering from lactose intolerance?

Bimuno contains lactose. However, the lactose content is well below that considered safe in most lactose intolerant people by the British Dietetic Association (BDA)5 and the European Food Safety Authority (EFSA)6.

Bimuno levels of lactose compared to official definitions of low lactose:


Is Bimuno suitable for vegetarians?

Bimuno® DAILY is suitable for vegetarians.

Does Bimuno contain artificial colours or flavourings?

Can my patient take Bimuno if they are on a low-FODMAP diet?

Yes, there is evidence to suggest that half a sachet of Bimuno® DAILY can be taken daily by individuals following a low-FODMAP diet. Although Bimuno is technically a fermentable fibre, the dose given and the specificity of the Bimuno GOS for bifidobacteria is thought to be the reason for why Bimuno can reduce flatulence, bloating and the associated abdominal pain.

Research has shown that individuals who experience flatulence, bloating and the associated abdominal pain found reductions in the above discomfort when taking Bimuno, at a comparable level to a Low-FODMAP diet1,7,8.

Prebiotic facts

What is the difference between prebiotics and probiotics?

Prebiotics are non-digestible food, for example non-digestible carbohydrates or polyphenols, that is selectively utilised by beneficial bacteria in the gut9. Prebiotics are not affected by heat and acidity and therefore reach the colon intact, where they exert a positive effect on the resident beneficial probiotic bacteria to confer a health benefit.

Probiotics are beneficial live bacteria which when taken in adequate quantities can confer a health benefit. Probiotics are susceptible to heat and acidity and therefore may not reach the gut alive.

What are the benefits of prebiotics over probiotics?

As probiotic supplements and foods contain live bacteria, they need to survive the passage through the upper gastrointestinal tract, the acidity of the stomach, secretions of the small intestine and then compete with existing bacteria for colonisation sites in the large intestine (colon). Not all commercially available probiotics can survive this journey in sufficient numbers to make an impact.

Prebiotics are ‘non-digestible’. This means that they reach the large intestine where they exert a beneficial effect on the resident beneficial bacteria so as to confer a health benefit.

How does Bimuno differ from other prebiotics?

Bimuno is rooted in scientific research. It is the product of an ongoing research and development programme conducted in collaboration with the University of Reading and other globally renowned research institutes. Bimuno is the most widely studied GOS supplement with its safety and efficacy supported by over 90 scientific publications including over 20 clinical trials.

Bimuno research is far reaching and demonstrates positive outcomes in gastrointestinal (GI), immunity, brain, cognition and mood, Traveller's Diarrhoea (TD) and cardiovascular functions.

Bimuno GOS differs from other prebiotics in its structure. The structure of Bimuno GOS is a reason for its specificity to feed bifidobacteria, an anaerobic bacteria that does not produce gas. Bimuno GOS can be given in a lower dose, whilst it still causes a prebiotic effect, a beneficial characteristic for those with sensitive stomachs10.
