Your Gut and Brain are Always Talking

Discover how your gut, microbiome and brain communicate -and what the science can teach us about supporting the connection.

Explore the Gut- Brain Axis

Your gut and brain are in constant communication. Signals travel in both directions through the nervous system, immune system, hormones and substances produced by microorganisms living in your gut.

It is a fascinating two-way relationship. Researchers are exploring how it may influence digestion, stress, mood and overall wellbeing.

What is the Gut-Brain Axis?

Plain-English Science

The gut–brain connection involves several fascinating biological pathways. Here are three important pieces of the puzzle.

The Vagus Nerve

The Gut Microbiome

Dietary Fibre & Fermentation

The vagus nerve is one important communication pathway between the brain and digestive system, carrying signals in both directions.

Your gut is home to a complex community of microorganisms. Researchers are studying how these microbes and their activities interact with digestion, immunity and the gut–brain axis.

Some types of dietary fibre are used by gut microorganisms during fermentation, producing substances called metabolites that are being studied for their potential role in gut and brain health.

Meet Your Microbiome

We bridge academic research and daily wellness, offering clear, unbiased science you can trust.

The microbiome is involved in digestion and interacts with the immune system and many other aspects of human biology. Researchers are also investigating how microbial activity may contribute to communication between the gut and brain.

A diverse, resilient microbiome is an important part of the gut–brain story — but there is still much to learn.

Supporting the Gut–Brain Connection

There is no single food, supplement or probiotic that holds the key to gut or mental wellbeing. A healthy gut is supported by a range of everyday habits, not just food. To support the gut brain connection there are many aspects to consider - fiber rich foods, plant diversity - aim to eat as many plant based foods as possible. Movement and sleep are also important. As far as possible lead a stress free life and look after wellbeing.

Probiotics: What Does the Science Say?

Probiotics are live microorganisms that, when consumed in adequate amounts, may provide a health benefit. But probiotics are not all the same. Different strains have different characteristics, and research findings cannot automatically be appto every product.

We look at the evidence behind individual strains, formulations and products — helping you understand what is known, what is promising and where the evidence is still limited.

Not all probiotics are created equal.Strain, dose, formulation and the health outcome being studied all matter.
