Gut-Brain Health
AT RE:HEALTH, WE TAKE AN INTEGRATIVE AND SCIENCE-DRIVEN APPROACH TO GUT-BRAIN HEALTH, RECOGNISING THAT WHAT HAPPENS IN THE GUT DOESN’T STAY IN THE GUT.
Your gut is often called your "second brain", and for good reason. Have you ever felt butterflies in your stomach when nervous or had a "gut feeling" about something? That’s the gut-brain connection in action—communicating through the vagus nerve, neurotransmitters, and immune pathways.
​
When this connection is disrupted—due to inflammation, imbalanced gut bacteria, leaky gut, or chronic stress—it can lead to digestive discomfort, brain fog, mood imbalances, and fatigue.
​
​If you're struggling with IBS, SIBO, food sensitivities, bloating, anxiety, or cognitive symptoms, we go beyond symptom management to uncover the root causes of gut-brain dysfunction, helping you restore balance and feel your best.
The Re:Health Approach
BEYOND SYSTEM MANAGEMENT
The gut does far more than digest food—it is a key regulator of brain function and mental well-being, and that the signalling is a two way street with messages passing from the brain to the gut and the gut to the brain. Research shows that gut imbalances can contribute to mood disorders, cognitive issues, and neuroinflammation, while chronic stress and brain inflammation can impair digestion and gut function.
​
​Instead of treating these issues separately, we take a root-cause approach, identifying biochemical, digestive, and metabolic factors affecting both gut and brain health—allowing for targeted, personalised support that restores balance in both systems.
Key Areas We Assess & Support
MICROBIOME IMBALANCES & DYSBIOSIS
The gut microbiome plays a key role in producing serotonin, dopamine, and GABA, the neurotransmitters that regulate mood, focus, and emotional resilience. Disruptions in gut bacteria (dysbiosis) can contribute to brain fog, anxiety, and depression.
LEAKY GUT & BRAIN BARRIER INTEGRITY
A weakened gut lining allows toxins and inflammatory proteins into the bloodstream, which can trigger immune activation, neuroinflammation, and mood disturbances.
SIBO (SMALL INTESTINAL BACTERIAL OVERGROWTH)
Excess bacteria in the small intestine can cause bloating, constipation, diarrhoea, and brain fog, as well as nutrient malabsorption and inflammation.
NEUROTRANSMITTER PRODUCTION & GUT HEALTH
Over 90% of serotonin and 50% of dopamine are produced in the gut. Gut imbalances can disrupt neurotransmitter function, affecting mood, motivation, and mental clarity.
INFLAMMATION & IMMUNE ACTIVATION
Chronic gut inflammation can trigger neuroinflammation, leading to fatigue, memory issues, and mood instability.
BLOOD SUGAR & METABOLIC FUNCTION
Blood sugar fluctuations can impact gut motility and brain function, leading to energy crashes, irritability, and digestive discomfort.
FOOD SENSITIVITIES & INTOLERANCES
Foods that cause an inflammatory response can contribute to brain fog, mood swings, and digestive distress.
MITOCHONDRIAL FUNCTION & GUT-BRAIN ENERGY
Both the gut and brain require high amounts of cellular energy to function properly. Mitochondrial dysfunction can lead to fatigue, sluggish digestion, and poor concentration.
VAGUS NERVE FUNCTION & NERVOUS SYSTEM REGULATION
The vagus nerve controls gut motility, digestion, and emotional resilience. A poorly regulated vagus nerve can result in bloating, stress sensitivity, and sluggish digestion.
Advanced Functional Testing for Neurodivergent Conditions
We use comprehensive lab testing to move beyond guesswork and identify the root causes of gut-brain dysfunction. Read more about lab testing here
YOUR PERSONALISED GUT HEALTH PLAN
Using data-driven insights, we create a tailored programme designed to restore gut function, reduce neuroinflammation, and support overall mental clarity. This may include:
​
Personalised Nutrition Strategies – A targeted approach to support gut healing, neurotransmitter production, and energy balance.
Targeted Nutritional & Botanical Support – Using evidence-based probiotics, prebiotics, postbiotics and herbal antimicrobials to rebalance the microbiome and gut barrier.
Nervous System & Stress Resilience – Supporting vagus nerve stimulation, breathwork, and relaxation techniques to regulate the gut-brain connection.
Ongoing Monitoring & Refinements – Regular check-ins to assess progress and refine strategies based on your body’s unique needs.
