Gut Health
You're outnumbered by the life inside you.
An estimated 100 trillion microbes live in your gut — and they help shape your digestion, immunity, metabolism and even your mood. The MY GUUT™ test reads that inner ecosystem and turns it into something you can act on.
Know your gut
Meet the ecosystem you've been carrying all along.
Clinical-grade sequencing, a simple home kit, and a report you can actually use. Get to know your microbiome with MY GUUT™.

The basics
What is the gut microbiome?
Your gut microbiome is the vast community of bacteria, viruses, fungi and other microbes that live in your digestive tract — mostly in the large intestine. Far from being passengers, they're working partners: breaking down fibre your body can't digest, producing vitamins and short-chain fatty acids, and helping train your immune system.
No two microbiomes are identical. Yours is shaped by your diet, sleep, stress, medication, environment and genetics — and it shifts over time. That's the interesting part: unlike the DNA you were born with, your microbiome can change, which makes it one of the more actionable windows into your health.
Researchers increasingly use the word diversity as shorthand for a resilient gut. A wide, balanced mix of species is generally associated with better health, while a narrowed or imbalanced community — sometimes called dysbiosis — is associated with a range of digestive and metabolic issues.
How it works
Three steps, start to insight
Embarrassment kills. People put off mentioning a change in their bowel habits because the subject feels awkward — and that delay is exactly what bowel cancer thrives on. So Dr Tang decided to meet the taboo head-on.
Every April, for Bowel Cancer Awareness Month, he leads an annual street campaign known as the Dirty Protest. Volunteers dressed as poo emojis and loo rolls march through UK city centres — from Manchester to Liverpool's John Lewis at Liverpool ONE — handing out treats, holding emoji balloons, and starting the conversations most people avoid.
The humour is the strategy. It's loud, it's hard to ignore, and it gives people permission to ask the questions they've been sitting on. Dr Tang is there in person to talk through signs and symptoms with anyone who stops.
Straight talk
What a microbiome test can — and can't — tell you
Microbiome science is genuinely exciting, but it's still a young field. MY GUUT™ is a research-grade insight and lifestyle tool — not a clinical diagnosis. It describes the composition of your gut and flags patterns and possible associations; it doesn't, on its own, diagnose disease.
Used well, it's a powerful starting point: a clearer view of your gut and practical, personalised steps around diet and lifestyle. Like all MeCheck tests, it's reviewed for clinical appropriateness by founder and GP Dr Chun Tang before listing.
If you have ongoing or worrying digestive symptoms — persistent pain, bleeding, or unexplained weight loss — please speak to your GP rather than relying on a microbiome report alone.
Why it matters
The gut touches more than digestion
Research increasingly links the state of the gut microbiome to systems far beyond the stomach. These are associations the science is still mapping — but they're why gut health has become such a focus.
Digestion & nutrients
Gut microbes ferment fibre, produce short-chain fatty acids that nourish the gut lining, and help synthesise vitamins like K and several B vitamins.
Immune defence
A large share of immune activity happens in the gut. A balanced microbiome helps the immune system tell friend from foe and supports a healthy gut barrier.
Metabolism
The microbiome is associated with how the body handles blood sugar, fat storage and weight — part of why two people can respond differently to the same meal.
The gut–brain axis
The gut and brain are in constant two-way communication. Research links microbiome balance to mood, stress responses and mental wellbeing.
Skin & inflammation
The gut–skin connection and low-grade inflammation are active areas of study, with the microbiome implicated in how the body regulates inflammatory responses.
