Overview of the Science behind Bimuno

Research on how the gut microbiome can be modulated through exogenous strains of beneficial bacteria (probiotics), has been well documented.

The effects of stimulating endogenous bacteria through consumption of dose-controlled prebiotics are arguably less well known.

Clasado has published human clinical trials on the prebiotic Bimuno® since 2008 and to date has over 90 scientific publications including over 20 clinical trials.

The research journey started at the University of Reading, UK by demonstrating how beneficial endogenous bacteria can be selectively grown in the colon using the galactooligosaccharides (GOS) contained in Bimuno.

Bimuno (also in publications referred to as B-GOS®) is shown to beneficially affect the human gut microbiome through its selective stimulation of bifidobacteria. The growth of good bacteria in the gut has been repeatedly demonstrated in studies in healthy adult populations1,2,3 individuals with IBS4,5,6 and obese adults7,8.

Human research has demonstrated the effect of bifidobacteria and associated metabolites on the gut microbiome, the host and the resulting influence on digestive health, immune health and cognitive health.

Digestive discomfort

Bloating, Flatulence and associated Abdominal Pain

Bimuno® has been shown to reduce the physical effects of digestive discomfort1,2,3,4.

Clinical research using Bimuno has shown that it reduces flatulence, bloating and abdominal pain in individuals who experience gastrointestinal discomfort and leads to a significant reduction in urgency2. Bimuno also has a positive effect on improving bowel habits in individuals with IBS4 and maintaining regularity in healthy individuals5.

It's important to note that by specifically targeting gut bifidobacteria (which do not contribute to gas production), Bimuno does not lead to increased gas6, which could be a concern for some individuals.

Digestive Discomfort

People who experience digestive discomfort are often advised by nutrition professionals to temporarily follow a restrictive diet which avoids fermentable (FODMAP) foods. Whilst this approach often yields short term benefits, a low FODMAP diet has a number of challenges as it can alter the gut microbiota, impact nutrient intake and diet quality, is complex to understand, requires the patient to be adequately supported to follow the diet accurately and safely, and lastly, not all patients respond to the diet1.

People who experience digestive discomfort respond more favourably to Bimuno GOS2,7 compared to inulin type prebiotics which may aggravate gastrointestinal symptoms.

Immune function

Immunity can be affected by lifestyle, stress, poor nutrition and it also changes as people age. Particularly with ageing, the decline of immune function - so called immunosenescence - may start to play a bigger role and can affect all parts of the immune system making a person more prone to getting ill.

Bimuno provides diverse benefits to the immune system. It improves immune resilience in the elderly1,2, improves low-grade chronic inflammation in the overweight3 and decreases asthma-associated pro-inflammatory cytokines4. Bimuno has shown to increase the level of anti-inflammatory cytokines and decrease the level of proinflammatory cytokines.

Immune Function

As many athlete’s experience GI problems and exercise-induced asthma, application of Bimuno to a physically active population could be advantageous. In addition, typically many athletes follow a high-protein, low-fibre diet so supplementation of Bimuno could help bridge the fibre gap.

Behaviour, mood and cognition

Modulation of the gut microbiome has also been demonstrated to affect behaviour, mood and cognition through the gut-brain axis. Bimuno supplementation has been shown to reduce stress through decreasing cortisol levels in healthy individuals1, impacting on their attention and mood.

In another study involving autistic children, supplementation with Bimuno led to significant improvements in social skills2. In an IBS cohort, Bimuno supplementation reduced anxiety and improved quality of life3.

Behaviour, Mood & Cognition

Travellers' Diarrhoea

Studies have shown that Bimuno reduces the adhesion of pathogens to gut cells and increases certain internally secreted substances to prevent invasion of pathogens. This strongly suggests a positive effect by Bimuno on the innate immune system. This effect is reflected in studies1,2 where Bimuno was shown to reduce incidence of diarrhoea caused by pathogens.
