The National Longevity Clinic operates from 69 Harley Street in London's Marylebone medical district, positioned as a health-optimisation and longevity practice. It was founded by cardiologist Dr Francesco Lo Monaco, a European Awards in Medicine winner in 2022 and 2024, together with Nutrition Practitioner Audrey Elena Ottaviani-Lo Monaco. Clinical services are delivered by doctors practising under National Heart Clinic Ltd, which is regulated by the Care Quality Commission.
The clinic pairs functional medicine with advanced diagnostics. Its comprehensive functional blood panels analyse over 250 biomarkers spanning hormones, micronutrients, inflammatory markers and cardiovascular indicators, alongside DNA and genetic testing, gut microbiome analysis, biological age assessment, VO2 Max testing, and imaging including full-body MRI and full-body ultrasound. Doctor-led medical services include cardiovascular care with inclisiran therapy, hormonal and endocrine optimisation, metabolic and weight management, and GP and preventative care from a female-led team.
Therapies include IV infusion therapy with formulations such as an NAD+ cellular support infusion, a vitamin C nutrient drip, iron infusions and a custom longevity blend, plus NAD+ therapy, red and infrared light therapy at 630 nm and 850 nm, and apheresis. Care is also packaged into three structured longevity programmes: ORIGIN (a weekend reset), ASCEND (30 days) and ZENITH (3 months).
