Introducing Bimuno

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, gut microbiome mediated health forms an important area of focus through its relationship to areas such as immune defence, immune health, cognition and even sport and athletic health.

A multiple award-winner in the nutrition industry, Bimuno is a proprietary galactooligosaccharide (GOS) ingredient that puts scientific research, performance, credibility 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 110 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 make the active ingredient of Bimuno. The structural properties (specific beta-linkages and a characteristic 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 known as a human milk oligosaccharide (HMO), a favoured substrate for bifidobacteria.

The GOS in Bimuno cannot be found in any types of food and unlike other oligosaccharides found in foods such as beans, garlic or pulses, Bimuno does not contain the alpha-linked galactose and alpha-linked glucose, with a terminal beta-linked fructose, known as fructans.

Instead, Bimuno contains solely galactose and glucose monomers within the GOS composition. The composition of our proprietary GOS makes it a preferred source of carbohydrates (over other sugars) for bifidobacteria, an important type of beneficial bacterial group of the gut microbiome.

The GOS in Bimuno is scientifically proven to be more selective towards bifidobacteria when compared to other commercially available prebiotic GOS, which lack this selectivity and can therefore be metabolised by many types of microbes, beneficial or otherwise.

In addition, key opinion leaders recommend that for some indications, such as irritable bowel syndrome (IBS), GOS with beta-linkages, such as Bimuno, is advantageous over plant-based prebiotics, such as FOS and Inulin, which contain fructan groups. Fructans may exacerbate symptoms of IBS.

Additionally, Bimuno has demonstrated positive effects on symptom relief in IBS sufferers or in individuals suffering from some undiagnosed GI discomfort.

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 a functional ingredient for gut health 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 110 scientific publications.

The research journey for Bimuno started at the University of Reading. Since 2004, Clasado has completed over 20 clinical trials on its unique prebiotic, demonstrating that Bimuno contributes to overall health and wellbeing.

Bimuno's key areas of effectiveness

Gastrointestinal Health

Promotes gastrointestinal wellbeing by reducing abdominal pain and discomfort, bloating and flatulence, and improving bowel regularity.

Cognitive Health

Reduces stress hormone levels and anxiety and improves mental health and cognitive function through the gut-brain axis. Studies on the efficacy of Bimuno are supported by human clinical trials data, the majority are also backed by preclinical in vitro and in vivo studies.

Immune Health

Modulates the immune system by increasing anti-inflammatory and decreasing pro-inflammatory biomarkers.

Immune Defence

Human trials have proven its capacity to strengthen the body’s natural defences and prevent diarrhoea caused by pathogens.

Sports Nutrition

Proven to support athletic health formulations through reduced incidence and severity of GI symptoms and supporting immune health, including upper respiratory symptom episodes.

Is the gut microbiome the key to health?

Over the past decade, research into 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 and its ability to affect our mental and physical health.

This revelation is driving scientists to look at the benefits of microbiome-altering technologies such as prebiotics, probiotics, synbiotics and postbiotics, which have been shown to have positive effects on human health.

As dietary fibre, prebiotic ingredient 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.
