About Us
At The Gut Guy, we’re a dedicated team of gut health specialists and naturopaths who believe that real wellness starts with clarity, not guesswork.
We use evidence-based testing and personalised support to uncover what your gut truly needs, helping you restore balance, improve digestion, and feel your best every day.
Our Story
After years of seeing clients struggle through endless supplements, restrictive diets, and conflicting advice, Josh Williams founded The Gut Guy to offer something different: a testing-led, data-backed approach that helps people truly understand what’s going on inside their bodies.
What started as one practitioner’s mission has now grown into a collaborative team of gut health experts, naturopaths, and holistic practitioners. Together, we share one goal: to help people stop guessing and start healing through insight, education, and support.
We believe in working with other professionals, not against them. Our team often collaborates with naturopaths, nutritionists, and functional health practitioners to ensure our clients receive complete care, addressing not just the gut but the person as a whole.
Our Mission
At The Gut Guy, our mission is to bring clarity, confidence, and connection to gut health.
We exist to help people who are tired of the trial-and-error approach. Our goal is to guide you toward a deeper understanding of your microbiome using science-backed testing and holistic care.
We believe true wellness comes from balance between data and intuition, modern research and natural healing, body and mind. That’s why we take the time to listen, educate, and empower every person we work with.
By combining functional testing with the expertise of our growing team, we’re helping more people across Australia move beyond symptoms and into lasting digestive wellness.
What Makes Us Different?
Multidisciplinary Approach
Our clinicians work together to create a targeted and personalised treatment plan and avoiding symptom management approaches.
If we can't help you, our clinicians have a list of trusted specialists that we can refer you to.
Advanced Gut Health Testing
Within 2 weeks, you’ll know if poor gut health is driving your symptoms and exactly what to do about it.
Our dedicated practioners will suggest additional tests, only if clinically appropriate.
Affordable Payment Plans
Natural health, personalised payment plans that give you full access to essential tests, consultations and supplements without paying for everything upfront.
Personalised Online Approach
We're Melbourne-based, but our services are 100% online. That means no clinic wait times, no travel, and flexible support.
All treatment plans, test kits and practioner-prescribed supplements will be delivered straight to your door.
Real Support, Zero Abandonment
Unlike other clinics, you can speak directly to The Gut Guy before committing to a paid consultation.
If you then decide to come on-board, The Gut Guy will be with you every step of the way, answering your questions, clarifying treatment plans, providing motivation all via 1:1 support phone consultation or email.
Avoid Endless Costs
Unlike other clinics, we don't mark up or overprescribe supplements, tests or consultations.
Our practitioner consultation fees are typically 25% lower than other clinics, with results seen in three sessions, not six.
