Welcome to Lantern Clinic
At The Lantern Clinic, we believe healthcare should be both comprehensive and personal. Our approach combines traditional medical expertise with modern functional medicine, creating a space where patients receive the time, attention, and understanding they deserve.
Our promise is simple: you'll have access to expert care when you need it, benefit from our holistic approach that addresses root causes rather than just symptoms, and gain access to innovative functional medicine solutions that conventional healthcare often misses. Whether you're booking a GP appointment or starting a longer health journey, you'll experience healthcare that truly listens.
The body has the ability and the innate wisdom to heal itself.
So many people desperately seek someone to listen and acknowledge the validity of their symptoms and this is what we do at the Lantern Clinic.
Our team is committed to helping you comprehend your body and symptoms, empowering you to make well-informed decisions tailored to your unique test results. This personalised approach epitomises the future of medicine, and we take great pride in being at the forefront of this transformative healthcare model.
Dr Margarita Kitova-John
MD, MRCGP, DFSRH, MSc, CFMP, and IFMCP
Dr Margarita Kitova-John is a GP with a passion for getting to the root of complex, chronic health issues. She founded Lantern Clinic to create the kind of care she wished existed — personal, thorough, and truly transformative.
With over a decade of NHS experience and specialist training in Functional Medicine, she supports patients with gut health issues, hormonal imbalances, and burnout. Her approach is warm, evidence-based, and always tailored to the individual.
"After more than a decade of working as a front-line GP, I have come to understand that the vast majority of chronic diseases are a result of the modern lifestyle: the food we eat, the stress we endure, and the toxic environment we live in. I believe the majority of them are preventable and reversible with the right holistic interventions.
I have learned and witnessed that the human body has the ability to repair itself. We must understand that the body's reserves are limited and that ageing negatively may affect the natural healing processes."
