Functional & Longevity Medicine
A personalised, integrated approach to health, Functional Medicine tackles concerns at the root cause.
Holistic, Proactive Health
Treating the Person, not the Symptoms
At PHC, we specialise in Functional Medicine, a holistic approach to understanding and nurturing the body and mind. We help those who may be frustrated by conventional medicine, to reclaim their health and wellbeing. Our leading team of Functional Medicine Doctors uncover the root causes behind many complex, chronic conditions via advanced diagnostics and comprehensive assessments. Combining this with extensive experience & knowledge in both conventional and functional medicine, they prescribe bespoke, personalised treatment plans and ongoing support programmes.
PHC Longevity Medicine represents a new, medically-led and functional medicine-informed approach to extending healthspan – the years lived in good health, rather than chasing unproven promises of lifespan extension. Unlike elitist longevity clinics that rely on gimmicks or fragmented interventions, PHC prioritises deeply understanding each individual’s baseline health through advanced testing, holistic assessment and root-cause analysis. From this foundation, medically validated, personalised intervention plans are created, using evidence-based tools that may include targeted nutrition, physician-led supplementation, peptide therapies (where appropriate), and structured lifestyle protocols. Every plan is co-designed with the client and we meet every client where they are at on their health journey, ensuring intentionality, readiness and long-term sustainability.
This vision is delivered through a multi-disciplinary team model that integrates functional nutritionists, physicians, elite trainers and clinical coaches underneath one unified framework, avoiding the confusion of mixed guidance. With data tracking from validated wearables, structured follow-ups and on-going care, clients can see measured progress in real time across key markers such as VO₂ max, sleep quality, metabolic health and heart rate variability. From a tailored baseline assessment to longitudinal reviews, every stage is designed to be evidence-driven and accessible, reclaiming the longevity conversation from exclusivity and grounding it in functional, personalised and realistic health optimisation.
HEALTH OPTIMISATION
“We use a functional medicine approach here at PHC which means we see every symptom and sign from a cell-up perspective. Rather than just asking ‘what can you take to fix it’ we ask ‘what has gone wrong and where’. We know that cells communicate with each other and whole systems are interconnected. It is this interconnectedness that is respected when we work with you on your health journey. We are here with you for the long distance – not just the sprint”
