Claire Clerkin

Nutritional Therapist, Lecturer, Clinic Supervisor and Academic Tutor

I have been in clinical practice for over 10 years, and I use functional tests every week to help get the best results for my clients. They are a fantastic part of our toolkit that can add real value to your practice.

However, it took me years to build the confidence to recommend pricey tests and confidently deliver value for my client's precious spend.

I have designed this course to give newly qualified practitioners the fundamentals of choosing, using and delivering functional tests. It's something I wish I had when I was starting out.

An overview of test analytes and what they mean.

 " This was a very comprehensive course, covering many tests and even included a visiting speaker for one class. I have learned a lot from it and now feel that have much more confidence in deciding which tests, and which companies, are valuable for different client issues. Thank you Claire." 

 " I finally found a course that is both value for money & where I learn information that is relevant to my current practice.
I loved that each test had its own lecture. Claire is very easy to listen to, is great to learn from and knowledgeable & experienced in her field. Each lecture is well structured, easy to follow & Claire provides relevant studies & documentation for you to use as a practitioner.

An excellent course to complete & the life time access allows me to go over the material again as & when I need it. Can't wait for more of Claire's courses." 

 " Every month after we had a session, I wanted to rush off and try the test out on myself!
I really liked the structure throughout - when would we test, 'selling' it to the client, interpretation, etc. I found that very helpful.
Showing the case studies made each of the tests more real."
