Gut health is surging to the top of the public health agenda, as studies uncover the true extent of beneficial gut bacteria’s influence. Consumers are becoming more proactive and informed on matters of health and wellbeing. Naturally, the gut microbiome forms an important area of focus through its relationship to areas such as immune health, cognition and even sport and athletic health.
Bimuno is a proprietary galactooligosaccharide (GOS) ingredient that puts performance and versatility at the forefront for product developers.
The most widely studied commercially available GOS prebiotic, Bimuno is supported by a comprehensive portfolio of research – over 90 scientific publications, including more than 20 clinical trials.
The proprietary GOS structure is derived from lactose, a natural component of cow’s milk.
What is the active ingredient of Bimuno?
A unique mixture of galactooligosaccharides (GOS) make the active ingredient of Bimuno. The chemical properties (beta-linkages and the degree of polymerisation profile) of our proprietary GOS drive the scientifically proven functionality of Bimuno.
Importantly, one of the structures in Bimuno’s GOS is 3-galactosyl-lactose which is also found in human breast milk oligosaccharides (HMOs), a favoured substrate by bifidobacteria.
The GOS in Bimuno cannot be found in any types of food and unlike oligosaccharides found in foods such as beans, garlic or pulses, it does not contain the alpha-linked galactose and alpha-linked glucose, with a terminal beta-linked fructose, known as Fructans.
Instead, Bimuno contains only galactose and glucose as structural components. The composition of our proprietary GOS makes it a preferred source of carbohydrates for the good gut bacteria, bifidobacteria.
The GOS in Bimuno is scientifically proven to be more selective towards bifidobacteria when compared to other commercially available prebiotics, which lack this selectivity and can therefore be metabolised by many types of microbes, beneficial or otherwise1.
In addition, key opinion leaders recommend that for some indications, such as irritable bowel syndrome (IBS), GOS with beta-linkages, such as the one in Bimuno, is advantageous over any plant-based prebiotics, such as FOS and Inulin, which contain fructan groups2. Fructans have been shown to exacerbate symptoms of IBS3,4. Conversely, Bimuno has demonstrated positive effects on symptom relief in IBS sufferers or in individuals suffering from some undiagnosed GI discomfort5,6,7.
What is the research behind the effectiveness of Bimuno?
Bimuno has been developed with science as its core driver, in order to offer food and supplement manufacturers an ingredient that provides value and that consumers can trust. The science behind Bimuno is one of the most comprehensive of any commercially available prebiotic, with its safety and efficacy supported by over 90 scientific publications.
The research journey for Bimuno started at the University of Reading. Since 2008, Clasado has completed over 20 clinical trials on its unique prebiotic, demonstrating that Bimuno contributes to overall health and wellbeing.

Is the gut microbiome the key to health?
Over the past decade, research into the microbial organisms that live in us has come to the forefront of human science. The gut microbiome, in particular, is now being coined as an organ in its own right, carrying approximately 150 times more genes than are found in the entire human genome. Scientists have recognised its impact on human physiology, as well its ability to affect our mental and physical health.
This revelation is driving scientists to look at the benefits of microbiome-altering ingredients such as prebiotics and probiotics, which have been shown to have positive effects on human health.
Bimuno has been shown to beneficially affect the human gut microbiome through its selective stimulation of bifidobacteria. The proliferation of good bacteria in the gut has been repeatedly demonstrated in studies in healthy adults8, elderly9,10, individuals suffering with IBS11,12 and obese adults13,14 .
|Indigestible fibre utilised by probiotics||Beneficial, living microorganisms which use fibre to thrive. Rarely permanently colonise the gut.|
|Nourishes the good bacteria that we already have in the gut||Needs to compete with present resident bacteria in the gut|
|Stable: not affected by temperature, acidity, storage time||Not stable: can be damaged by heat and acid; sensitive to storage time|
|Not affected by stomach acid and digestive enzymes||Can be killed off by the pH during transit through GI tract|
|Recommended dose of GOS for GI symptom relief: 1.37 g/day; for prebiotic effect, immune system modulation, antipathogenic activity, brain health and function: 2.75 g/day||Desired benefits depend on effective dose/serving size and strain used|
