After you’ve received your test kit, collect your samples and return them to the lab.

We’ll promptly deliver your results to you once they’re processed.

Our team provides commentary on all lab findings, assisting you in understanding their implications.


Are you curious about the difference between a GI MAP and a Genova GI Effects or a GI 360? Perhaps you’re interested in understanding which test delves into your gut microbiome, or you’re seeking specific insights like Lactobacillus Acidophilus, candida yeast, or molds. Discover the answers you seek in our newly crafted comprehensive digestive test comparison table.


Functional medicine takes a comprehensive approach to understanding the origins of illness and aims to restore health by addressing individualised root causes, which may vary even among those with similar diagnoses.

Smart Nutrition uses functional medicine’s cutting-edge scientific testing to provide clients with an in-depth understanding of their personal health picture.


As the leading UK SIBO test provider, we’ve conducted thousands of tests over 15 years. With results in just 3 days, our test uses more breath samples, than most ensures accuracy. Plus, our expert team provides detailed comments with your results for comprehensive insights.


Our Genetic Methylation Test is one of our best sellers. Find out if you can methylate efficiently. The test covers everything that the popular you tube star Gary Brecka’s 10X DNA test checks for but our test goes a few step further and checks for an extra 22 extra genes.

Just wanted to say a big thank you for all of your help through a very difficult time. I'm back eating everything now (have been for a while) which is amazing! And have weaned myself of needing any supplements. I really appreciate your had work and guidance technically but also helping me tune into my body and what it needs.

Thanks to your expertise and diligence in checking everything when the provisional diagnosis of SIBO didn't quite ring true with you, I was officially diagnosed with Exocrine pancreatic insufficiency (EPI) (after a second sample was taken for confirmation at the GP). I'm really grateful for you finding it as I don't know where I'd be otherwise!

I just wanted to say thank you very much for the service you provide. It was such a relief to finally have an answer after years of digestive troubles. I have managed to get a prescription for Rifaximin from my GP (albeit only for twice a day dosing, not three times a day) and I’m combining it with garlic and ginger.
