We Do Not Offer Testing Only Services

As the leading functional medicine clinic in the UK, we support our clients in optimising their health and tackling illnesses. To do this we offer tests that help us identify the root cause of their health concerns. With that in mind, our testing services are only for patients under consultation with our expert practitioners.

Mentoring for registered Nutritionists

Personal mentoring with experienced Nutritionist & Functional Medicine Practitioner Oliver Barnett.



The London Clinic of Nutrition is one of the largest integrative and functional medicine practices in Europe, with a team of 25 staff members and a reputation for helping thousands of patients regain their health. Our mentoring programme is ideal for anyone looking to expand their outreach, upscale their business, and develop their knowledge in a variety of disciplines including functional medicine, microbiome testing, autoimmune disease, and more.

A unique aspect and an additional benefit of Oliver’s mentoring package is the ability for participants to regularly observe Oliver in Practice with his own clients.

Learn from one of the UK’s leading Nutritionists and Functional Medicine practitioners

Oliver has worked in the wellness industry for nearly 20 years and has supported over 20,000 clients with a range of conditions to improve their health and wellbeing. He started as a sole practitioner, before founding and building LCON into one of Europe’s leading functional medicine practices.

Along the way, he developed his unique multi-disciplinary approach, combining nutrition, naturopathy, herbal medicine, functional medicine, and psychotherapy. After experiencing a spiritual awakening in 2017, this approach expanded to include spiritual, soul work, and energetic medicine so that healing comes from a place of self-love, compassion and awareness within the patient.

Support for aspiring Nutritionists or holistically minded Health Practitioners

Oliver intuitively created an approach that draws upon nearly two decades of training, self-development, and work with thousands of patients. He is now offering other practitioners the opportunity to work with him to develop their own style and approach, at any stage of their journey.

Much as Oliver guides his patients to a place of self-healing and intuitive living, he uses this approach to help his mentees develop as practitioners.

Each approach is bespoke and will focus on what the mentee would like to address, whether this is deepening and developing what they offer their patients, or perhaps looking at how a clinical practice is commercially developed and sustained.

Perhaps you’ve graduated with a degree in nutrition but feel like you need more support, before you are ready to work one to one with clients? Observing Oliver in practice with his own clients will provide great insight into the processes here.

Perhaps you find yourself being approached by clients with complex and chronic health issues that you don’t yet feel qualified to handle. Are you feeling overwhelmed or concerned that you don’t have all the answers?

Or perhaps you are already working with clients and are looking to develop a sustainable business strategy or increase your offerings, including functional medicine, microbiome testing, autoimmune disease and more?

With Oliver’s support, you will work through your challenges, grow as a practitioner, and develop your own sustainable approach to your practice and patients.

Package options

The package is for a minimum of six months, although we will consider monthly subscriptions depending on individual circumstances.

This includes two hours of Oliver’s time each month broken down into one or two sessions.

Email support is also available, as well as ad hoc telephone calls where needed.

Prices are as follows:

  • Monthly £400 per month
  • Six month package  £2,000
  • 12 months package £3,500
