24/01/2018 - We have temporarily paused 16s gut microbiome testing to launch our new personalised nutrition service. Contact us to be an early access customer.

Comprehensive gut microbiome analysis and interpretation, available exclusively through accredited Health Professionals.



Thousands of bugs live in your gut. Some are associated with good health, and some are known to be linked to certain diseases. At MapMyGut we assess the diversity of your gut ecosystem using the latest DNA sequencing technology. This means that we’re able to identify the microbes that inhabit your gastrointestinal system by means of “matching” pieces of bacterial DNA, so we literally create a map of the microbial contents of your gut, hence the name. Our microbiome specialists then add an individualised analysis of your results. Finally, we create a thorough report that describe the key microbes we’ve found living inside you and what they mean for you and your health.

Our tests are available exclusively from one of our accredited health professionals. They will provide you with a kit and will keep in touch with us so they know where your sample is from the moment you send it back to us to the time your results are released, at which point your health professional will contact you to arrange to discuss those with you. Your health professional will guide you through your report and, armed with the powerful information featured in it, will provide you with individualised dietary and lifestyle recommendations that work for you. All our accredited health professionals have extensive experience in using micriobiome assessment and other functional tests and have passed the stringent MapMyGut professional accreditation process.

24/01/2018 UPDATE: We have temporarily paused our 16s gut microbiome testing to launch our new personalised nutrition service, which will include an assessment of your unique microbiome and the identification of foods that may help you to improve your gut, weight and overall health.

Contact us if you want to be part of our early access customer group, mentioning your interest, and the MapMyGut team will get in touch with you.


The 16S

Standard sequencing method for microbiome tests. It measures a single gene present in all bacterial DNA called 16S that allow us to classify most of the common bacteria present in your gut. Most population data we have is based on this method.

Following the analysis our team of microbiome experts will asses the results and identify how the different groups of microbes associate to health and disease. This information will allow your health specialist to provide you with personalised nutritional and lifestyle advice.

The current turnaround time is currently 6 to 8 weeks and your practitioner will be able to keep you updated of the process. Click here to contact us.

Why are we different?

MapMyGut tests are available through one of our professionals exclusively.

Why?  Because every health professional we accredit becomes a long-term research partner who will work with us to help us understand the relationship between the foods you eat and your gut microbes. We have selected our team of practitioners on the basis of their training and clinical experience of using functional tests. Aside from their professional qualifications, they're all registrants of registers accredited by the Professional Standards Authority and they're all committed to continuing professional development, complete 100s of hours of work-based learning on the microbiome every year. We trust them to be able to help you at every step of the way, from ordering your test kit and explaining what your results mean, to issuing individualised dietary and lifestyle recommendations that are relevant to you thereafter.

What our tests are not

Our tests do not provide medical advice and they are not medical diagnostic tools. Our microbiome tests are not medical tests.  Our tests and subsequent report are designed to provide your accredited health professional with insights into the state of your gut microbiome, enabling them to provide you with nutritional, dietary, lifestyle and other advice you deem appropriate.

Our microbiome tests are not intended to be and are not sold as medical diagnostic tools. If you've any doubts about what this means to you, we recommend you read our terms of service.

  • Claudia's microbial profile showed she has very few firmicutes - which normally make up about a third of the total microbial community. An imbalance in this group is associated with poor diet and obesity. We know that junk food diet can halve the number of firmicutes in the gut in just a few days. Levels of enterobacteriaceae associated with poor diet were also high. We know that this microbe is associated with inflammation and in old people frailty, putting them at risk of hospitalization.

    Claudia was recommended periodic fasting as this increases microbial diversity and straightens how the bacteria interact with the gut lining increasing her metabolic functions. We know that a diverse microbiome produce more healthy chemicals with reduction in weight gain. Claudia stated:

    I am now taking a probiotic, trying the 5:2 diet and exercising more. I feel better already with more energy and have lost weight. This has been the kick start I needed to reboot my unhealthy lifestyle.

  • Malcolm's gut microbiome analysis showed that, unusually, 50% of his gut microbiome contained a bacterium called pseudomonas generally associated with inversions. He also had a very low proportion of firmicutes which is associated with a poor diet and obesity and a slight increase of enterobacteria associated with IBS and common on people on junk food diets that can produce toxins.

    Malcolm was asked to make dramatic changes to his diet to stop processed foods and replace them with a wide range of fruits and vegetables. We know that the chemicals found in processed food are very detrimental for the microbes. Also, most processed meets have traces of antibiotics in them which contributes to reducing the microbial population further. Malcolm stated:

    My diet is very heavy in sandwiches and refined carbohydrates and low in fibre. These results have encouraged me to slowly include more fruit and vegetables in my diet as well as reducing refined carbohydrates and processed meats.
