Are there any costs other than the tests and the supplements?

If you're worried about any extra costs outside of the tests and supplements, rest assured that we will never charge for 'extras'.

There are no further costs involved. The advice we give based on the results of your tests is free.

We’re proud to provide your test at the same price available across the market, privately through practitioners. In addition, you’ll receive:
  • An easy-to-read report of your results
  • Personalised review of symptoms by our practitioners
  • Personalised health plan
Included with your test, we also provide the following Healthpath support:
  • Our knowledge base, with all the answers to your questions
  • Our group support calls, where you can talk to our team of experienced practitioners

Coming soon, we'll also be launching:

  • our community, where like-minded people chat, with guidance from our experts
  • our library, with educational materials on improving gut health


Your symptoms review, test results and health plan have everything most people need to get on the road to recovery, along with the support platforms and education we’ve created.

If you need personalised help

Sometimes, only highly personalised 1 to 1 support over a longer period with an experienced, highly skilled functional medicine practitioner will do.

Speaking to a practitioner over a video call is a separate service. We only recommend doing that if you have ongoing problems with your symptoms, or you find the protocol we've put together too difficult to follow. 

Returning your samples

If you're in the UK, just use the FREEPOST label that came with your kit. If you're outside the UK, or you want to arrange special delivery, you'll need to arrange the right fee from the postal service in your country and return the sample to the laboratory within the right timeframe to ensure your sample is valid.
