The Evidence Behind Our Prebiotic

Our prebiotic blend has been studied for over a decade in universities and clinical research centres. Across multiple human trials, it has consistently been shown to nourish beneficial gut bacteria, especially bifidobacteria, supporting digestive comfort, immune balance and overall wellbeing.

Clinical Studies

Supports Digestive Comfort

Several clinical studies show that our prebiotic helps create a healthier balance of bacteria in the gut supporting more comfortable digestion in everyday life and in people with sensitive guts.

Everyday Digestive Discomfort

In adults who regularly experienced bloating, gas or abdominal discomfort, daily use of the prebiotic for just two weeks led to:

  • Less bloating
  • Less gas
  • Reduced abdominal discomfort

These improvements appeared within the first week of use.

Irritable Bowel–Type Symptoms

In people with IBS-like symptoms, studies found:

  • Improvements in bloating and gas
  • Better overall digestive comfort
  • Increased levels of beneficial bifidobacteria

Different doses benefited different symptoms, showing the importance of personalised use.

Travel-Related Gut Upset

In two large studies with travellers visiting higher-risk destinations, those who took the prebiotic:

  • Experienced fewer episodes of travellers’ diarrhoea
  • Had shorter and milder symptoms if it occurred
  • Reported better overall wellbeing while travelling

What this means

By helping beneficial bacteria thrive, the prebiotic supports a more resilient gut - whether at home, on the go or in sensitive digestive situations.

Clinical Studies

Supports a Balanced Immune Response

Several studies in both younger and older adults show that our prebiotic can positively influence markers linked to immune function.

In Older Adults

Clinical trials reported:

  • Increases in beneficial gut bacteria associated with healthy ageing
  • Shifts in immune markers toward a more balanced, less inflammatory profile
  • Enhanced activity of natural killer (NK) cells and phagocytes—important parts of the body’s defence system

In People with Metabolic Risk Factors

In overweight adults with multiple risk factors, the prebiotic:

  • Increased beneficial gut bacteria
  • Supported healthier inflammatory and immune markers
  • Was associated with modest improvements in cholesterol, triglycerides and insulin levels

What this means:

A healthier gut ecosystem is closely linked to immune balance. These studies suggest the prebiotic can help support that connection.

Clinical Studies

Supports the Gut–Brain Connection

Emerging research shows that the gut and brain communicate through nerves, hormones and immune pathways. Our prebiotic has been studied in this area too.

Stress & Emotional Processing

In healthy adults, taking the prebiotic for three weeks:

  • Reduced the morning cortisol awakening response (a key stress hormone pattern)
  • Shifted emotional attention away from negative cues and toward positive ones during cognitive testing

Cognition & Behaviour (Early Research)

In People with Metabolic Risk Factors

Small exploratory studies in people with cognitive or neurodevelopmental challenges found:

  • Changes in gut bacteria
  • Shifts in metabolic by-products made by gut microbes
  • Improvements in specific cognitive or behavioural measures in some groups

These are early-stage findings and require larger trials, but they highlight how the gut microbiome may influence brain-related processes.

What this means:

While these studies don’t make medical claims, they support the emerging idea that nurturing beneficial gut bacteria can play a role in how we respond to stress and process emotional information.

Clinical Studies

Supports the Gut–Lung Connection

A small study in adults with exercise-induced asthma explored how the prebiotic might influence immune responses linked to the airways.

Participants experienced:

  • A less severe drop in lung function during a controlled breathing challenge
  • Reductions in certain inflammatory markers associated with airway irritation

What this means:

This suggests a potential gut–lung link, where supporting the microbiome may help balance immune responses elsewhere in the body. This is exploratory research and not a treatment for asthma, but it’s a promising area of study.

Clinical Studies

Why the Research Matters

Across all studies—whether in healthy adults, older individuals, travellers, or people with digestive sensitivities—the findings consistently show:

  • An increase in beneficial bifidobacteria
  • Better balance of the overall microbiome
  • Support for digestive comfort
  • Shifts in immune and metabolic markers toward healthier patterns
  • Signals that the gut–brain and gut–lung connections may be influenced by prebiotic nourishment

The benefits come not from adding bacteria, but from feeding the beneficial microbes already within you, helping them thrive and support whole-body wellbeing.

What You Can Expect

While individual experiences vary, many users report:

  • More comfortable digestion
  • Less bloating and gas
  • A more settled gut during travel
  • A general sense of improved wellbeing over time

Most studies show effects building over 3-4 weeks of daily use.
