Compositional Gut Test

The Compositional Gut Test quantifies the total amount of bacteria in the gut as well as the levels of key beneficial bacteria and the most common problematic bacteria.


When it comes to your body, your gut is at the epicenter of the action. So, it is no surprise really, when something isn’t quite right in your gut, it can affect many aspects of your physical and mental health. Gut health testing is a great way to get to know your gut better.

Bifidobacterium – Genus (approx. 47 species)

Problematic bacteria:

E.coli – species
Clostridium difficile – species
Fusobacterium nucleatum – species
Proteus mirabilis – species

Who should test?

Gut health testing with the Compositional gut test is ideal for anyone having issues like bloating, constipation, anxiety, fatigue, allergies or joint pain, or for those without any issues at the moment who would like to keep it that way!

Benefits of balancing bacteria in the gut

Eating a more diverse diet which includes lots of prebiotic and fermented foods, staying well hydrated and having regular, moderate exercise and optimum sleep can go a long way to improving gut health. Benefits can include a more balanced and effective gut microbiota, which can in turn contribute to better overall physical and mental wellbeing.

When and how to collect a sample?

Collect your stool sample anytime following your typical diet and lifestyle so that your results are representative of your normal routine. Try to avoid changing anything for a couple of weeks before collecting your sample as this can over-estimate your scores.

The instructions will be in your kit, but here is a digital version if needed.

Mandy Brown

Good service. Test report clear and concise. The only downside for me was the colour of the packaging – white writing on a yellow background. I found it really difficult to read. The instructions inside were also very faded ink. If you are doing this for the first time, the last thing you want to be doing is struggling to read the instructions

The test was easy to do at home and from activating the test all the way through to the report, there was clear communication. The test report was very clear and concise and written in plain English and not technical. I am now able to take measures to counteract a deficiency. Amazing service from start to finish

Simple and easy to use in the comfort of my own home. Results came through pretty quickly. I would definitely recommend to others and I will use this for my client as a nutritional therapist it’s good to get an understanding of baseline levels before adding any supplements.

I found out my results were poor after taking the test and started taking Omega 3 capsules. I was plagued with migraines having 2 a week roughly and am delighted to say they have gone. Can’t recommend this product enough!
