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. | 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. |

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.
