Redefining Health Optimisation

Health is built daily. Through lifestyle, nutrition, and function. At the National Longevity Clinic, we build a plan tailored for you. Based on what your body needs, and how it reacts to interventions. Our approach is entirely proactive. We start before decline begins, disease takes root, and health deteriorates.

1. Initial Consultation

A deep dive into your medical history, lifestyle, and longevity goals.

2. Diagnostic Assessment

Advanced testing across hundreds of biomarkers to establish your biological baseline.

3. Medical Intervention

Personalised protocols combining medical therapies, nutrition, and lifestyle adjustments.

4. Monitoring & Re-Evaluation

Continuous tracking and refinement to ensure sustained improvements.

Clinical Excellence Meets Precision Longevity

The National Longevity Clinic is the vision of Audrey Elena Ottaviani-Lo Monaco, a certified nutritional practitioner and functional medicine expert, whose own health journey inspired a different approach to healthcare. As the founder, she believes that medicine must restore vitality, not merely treat disease. This philosophy is shared by co-founder Dr Francesco Lo Monaco, an award-winning cardiologist whose career bridges rigorous science and compassionate care.

Twice honoured at the European Awards in Medicine (2022 & 2024) and named Fluxx Global Cardiologist of the Year 2025, Dr Lo Monaco has earned over 500 five-star reviews and recognition among the top 10 percent of clinicians in London. Yet the story goes deeper than accolades.

Together, they built a clinic where science meets soul, blending precise diagnostics, evidence-based protocols, and profoundly personal care to help each patient reclaim their health and longevity.
