Lucio Health is a London-based integrative medical service specialising in personalised, adjunctive support for people living with or recovering from cancer, as well as individuals managing complex or long-term health conditions. The service combines evidence-informed interventions with a comprehensive, patient-centred model of care designed to complement standard medical treatment pathways.
Lucio Health’s medical lead and co-founder is Dr Hariharan Kuhan. Dr Kuhan completed his undergraduate training at Imperial College London, where he also obtained a BSc in Surgery and Anaesthesia. He undertook foundation and core medical training in Central London, holding posts at St Mary’s Hospital and St Bartholomew’s Hospital, before developing extensive experience in Medical Oncology at leading centres including St Bartholomew’s, University College London, and the Royal Marsden Hospital.
He subsequently held a research fellowship at Barts Cancer Institute funded by Stand Up To Cancer and HCA Healthcare, focusing on metabolic vulnerabilities in cancer stem cells and circulating tumour cells, including the use of repurposed medicines and vitamin C in laboratory models. He later joined the Sarah Cannon Research Institute (Harley Street) as a sub-investigator on multiple Phase I and II solid tumour trials, gaining experience in translational oncology and the integration of next-generation sequencing into clinical decision-making.
Dr Kuhan co-founded Lucio Health with long-time associate Raphael Swery with a shared vision to create a service that is both patient-focused and forward-looking. Lucio Health aims to bridge the gap between laboratory science and lived patient experience—bringing insights from genomics, metabolic oncology, and integrative medicine into practical, compassionate, and highly personalised care.
The clinical approach focuses on understanding each person’s medical background, treatment history, and goals, enabling the team to develop tailored plans that support resilience during treatment, optimise recovery, and address factors contributing to chronic symptoms. Our care is aligned with each patient’s oncology treatment or follow-up plan, ensuring it remains fully compatible with standard oncology care.
Lucio Health provides structured assessment and follow-up, advanced diagnostic testing where appropriate, and ongoing clinical guidance. Where beneficial, this may include next-generation sequencing and specialised blood or tissue analyses to help build a clearer picture of each person’s health. These insights support more personalised discussions around metabolic, nutritional, and lifestyle strategies that sit alongside standard oncology care.
Treatment plans may include metabolically-targeted support (for example, using evidence-informed strategies that consider how the body’s metabolic pathways respond to illness and treatment), nutrition, movement, lifestyle interventions, and strategies to help manage treatment-related side effects. The team also supports people living with other chronic health concerns where metabolism, hormones, inflammation, or cardiovascular risk may be contributing factors. This includes issues such as blood sugar and insulin imbalance, changes in weight or body composition, chronic inflammation, metabolic dysfunction, hormonal disturbances affecting energy or sleep, and cholesterol or lipid-related concerns.
Care is offered through in-person consultations at 10 Harley Street or remotely via secure video appointments. The service operates Monday to Friday and provides an out-of-hours line for urgent queries directly related to the care offered by Lucio Health.

Dr Hari is an excellent physician and I cannot recommend him enough. He is factual while never losing sight of the essential trauma that a Cancer diagnosis can bring. I am exceedingy pleased I contacted him, his help has been enormous and his approach to the Metabolic system is exactly what we needed.
My experience with Lucio Health was absolutely wonderful. All my questions were answered time and time again, I was treated with dignity, warmth, professionalism and empathy, many of the traits lacking in a lot of oncologists providing standard of care. Choosing Lucio Health was the best choice I have made, so far, and every time I interact with them I feel positive and at ease. I literally can't fault them.
Over the past year, I’ve been through the biggest battle of my life, and Dr. Hariharan Kuhan made a profound difference throughout the journey. From the beginning, he treated me as a person, not just another patient or number. He always approached my case with honesty, patience, genuine care, and an open mind. During difficult moments, his calm guidance helped me face everything with more clarity, confidence, and hope. One of the most important parts of my journey was the integrative metabolic approach we built together, with the goal of supporting my body through treatment, improving recovery, helping maintain remission, and giving me the best possible quality of life throughout the process. His guidance helped me regain strength both physically and mentally during an incredibly demanding period. Beyond the medical side, his encouragement, reassurance, and human approach had a huge impact on me personally. I’m deeply grateful for his support throughout this chapter of my life.
I was impressed by the speed of response to my request for a consultation, and for the amount of ground covered in the online session that followed soon after. I then received a written report providing a detailed account of what was said in the session, along with considerable further information relevant to my treatment and situation. Overall, I had a sense of being held throughout the process, and the immediate outcome for me was a feeling of trust in the experience and knowledge of the consultant.
I came across Lucio Health and Dr Hari via Dr Hari's published book, and Astron.. Dr Hari has helped me work out a protocol, in absolute conjunction with my NHS team.. giving me some hope in what feels like a hopeless world.. In such a thorough, detailed, clear way - with the logistics of contact/booking/consults etc being easy and follow up reports being very clear.. exactly what I needed 🙏🏽
Dr Hari is very knowledgeable and attentive. He answers all my questions thoroughly and with care. He has given me hope, based on science and evidence, which I truly needed.
I don’t know if any amount of space is enough to truly express my gratitude to Dr. Kuhan. He has been an incredible source of support and a pillar of strength for me during one of the most difficult times in my life. My father is currently healing from stage 4 cholangiocarcinoma, and from day one, Dr. Kuhan gave us something we desperately needed—strength and hope—despite the challenges of this diagnosis. I didn’t hesitate to begin the protocol he personally designed for my father. What stood out even more was the unwavering support that followed. Every time I reached out, Dr. Kuhan took the time to carefully analyse the situation, explain things clearly, and give us a realistic understanding of what was happening—along with practical guidance on how to handle each step. In India, it can often be difficult to have detailed conversations with doctors or get clear explanations. With Dr. Kuhan, it was the complete opposite. He was always accessible, patient, and thorough. My family and I have relied heavily on him, and he has never let us down. What reassured me the most was when, after a phase of treatment, I asked our oncologists here about my father’s progress. Without knowing about the integrative protocol, they mentioned that he was doing better than other patients with a similar diagnosis. That was a powerful confirmation for us that we were on the right path. I am deeply grateful that we were connected to Dr. Kuhan. I truly believe our family would not have had a moment of peace without his guidance and support. Thank you, Doctor, from the bottom of my heart. God bless...

Dr Kuhan and the Lucio team are superb -- kind, approachable and are experts in what they do. They are making a huge difference to us when faced with a complex and challenging health situation.
