Our success with Functional Medicine at the London Clinic of Nutrition

As the UK’s largest functional medicine clinic, we pride ourselves on clinical excellence. As a premier nutritionist in London, our expert functional medicine doctors combine industry-leading nutrition and functional medicine expertise, alongside the latest laboratory testing, so we can attend to all your health needs in one trip.

As an award-winning integrative medicine clinic, we are proud to have received the UK’s highest award from Integrative Healthcare & Applied Nutrition (IHCAN).

Over the last 10 years, we have managed to turn many of our clients’ lives around by supporting numerous complex, chronic illnesses. We specialise in numerous health conditions, including; Lyme disease, autoimmune disease, gut health, hormone health and unexplained illness.

To understand what to expect when you attend the clinic and how successful our approach is, please have a read of our Google reviews and testimonials.

To offer best access we typically see our patents online via virtual appointments, meaning we can support people from all over the world. However, we understand that sometimes people prefer face to face appointments, therefore upon request we can make appointments in one of our pop up clinics in London.

Why Patients Choose the London Clinic of Nutrition

There are a growing number of functional medicine clinics in London. If you’re comparing practitioners, our guide explains how to find a good functional medicine doctor. Here is what makes the London Clinic of Nutrition different. Our approach is built on the idea that each patient’s biology, genetics, and history is unique. We call this biochemical individuality. Rather than applying standard protocols, we investigate what is actually driving your symptoms.

Deepest Lyme Disease Expertise in London

One of the only clinics in the UK with a dedicated Lyme disease investigation pathway. We screen for co-infections and support patients with long-term post-treatment symptoms.

Users

A Multi-Practitioner Team, Not a Solo Clinic

Our clinic has a team of functional medicine doctors and nutritional therapists, each with their own area of expertise. When your case is complex, having multiple specialists available makes a real difference.

10+ Years of Documented Outcomes

Over a decade of managing complex chronic conditions across Lyme disease, chronic fatigue, autoimmunity, and gut health. That depth of experience is something newer clinics simply cannot offer.

Paediatric Functional Medicine

We work with children as well as adults. This includes complex cases involving Lyme disease, gut health, and nutritional support for children with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Paul Foley and Lelani both specialise in paediatric presentations.

Cancer Support Alongside NHS Care

We provide nutritional support for cancer patients as a complement to NHS treatment. Daisy, our oncology nutrition specialist, works with patients in active treatment and recovery. One patient credits their father’s NED status to the plan that the clinic put together.

Mould, Mycotoxin and Toxicity

One of a small number of UK clinics with clinical experience in mould illness, biotoxin illness, and CIRS. Oliver Barnett, Paul Foley, Daisy, and Lelani all hold this as a specialism — making LCON one of the most experienced teams in the UK for this presentation.

Our Functional Medicine Team

At LCON you are cared for by a team, not a single clinician. Your lead practitioner will have specialist depth relevant to your presentation.

Conditions We Investigate and Support

Functional medicine works especially well for conditions where standard testing has not given a clear answer. This often applies when chronic inflammation, immune problems, or several body systems are involved at the same time.

What is functional medicine?

Functional medicine is a systematic approach that aims to discover the reasons behind your symptoms. This is where it differs from traditional approaches that try to treat or suppress the symptoms without ever really addressing the root cause.

At the London Clinic of Nutrition, we treat you as an individual; with a unique complex and interwoven set of circumstances, environments and physiology.

Functional medicine is evidence based and has been proven to help in the treatment of:

  • Long Covid
  • Autoimmune Disease
  • Thyroid (Over and Underactive)
  • Lyme Disease
  • Chronic Fatigue
  • Skin Conditions
  • PCOS
  • Fertility
  • Gut Health
  • Toxicity
  • Weight Loss
  • IBS

This includes some of the most common conditions we support using functional medicine, however we also have considerable success working with clients who experience many unexplained illnesses.

Why use a functional medicine approach?

Often we find that the causes of an illness can be seemingly unrelated issues. For example, chronic fatigue syndrome or joint pain may be caused by digestive issues or thyroid problems.

Functional medicine helps us piece together the puzzle and take a more integrated, holistic understanding. After using a systematic approach to assess your symptoms we create an individualised plan tailored specifically to your needs.

Frequently Asked Questions

Answers to the questions we hear most often from patients considering functional medicine for the first time.

QWhat is a functional medicine doctor?

A functional medicine doctor investigates the root causes of illness rather than treating symptoms alone. They use advanced lab testing, nutritional science, and lifestyle medicine to understand why you are unwell and build a plan around that.

QWhat does functional medicine treat?

Functional medicine works well for complex or chronic conditions including Lyme disease, chronic fatigue, ME/CFS, autoimmune conditions, gut problems, hormone imbalances, Long COVID, brain fog, skin complaints, and cardiovascular health. It is also used alongside NHS cancer treatment.

QHow is functional medicine different from a regular GP?

A GP diagnoses and treats conditions based on clinical guidelines. Functional medicine asks why you developed the condition and what can be done about the root cause. The testing goes further too looking at gut health, inflammation, hormone balance, and immune function rather than just checking for disease markers.

QIs functional medicine available on the NHS?

Not currently. Functional medicine is offered by private clinics. The London Clinic of Nutrition has over a decade of experience and offers a complimentary discovery call so you can speak with the team before making any commitment.

QHow much does a functional medicine consultation cost in London?

The cost depends on your needs, the testing involved, and the practitioner you see. The best starting point is a complimentary discovery call, no obligation, and it gives you a clear picture of what your care would look like before you decide.

QDo you offer functional medicine for children?

Yes. We work with children presenting with complex or chronic health conditions including Lyme disease, gut problems, nutritional deficiencies, and ASD-related presentations. Please mention during your discovery call that you are enquiring about a child.

QWhat makes the London Clinic of Nutrition different?

Three things. First, deep Lyme disease expertise. We are one of the only clinics in London with a dedicated co-infection investigation pathway. Second, a multi-practitioner team rather than a single clinician. Third, over ten years of documented patient outcomes.
