What happens when a former finance executive who experienced burnout firsthand reveals why cellular health may be one of the most overlooked foundations of performance, recovery, and longevity?

In this episode of Becoming Limitless, Dr. Elie sits down with Iain de Havilland, founder and global CEO of NAD Clinic Group, to explore the science behind NAD+, cellular energy, burnout recovery, and the future of evidence-based longevity medicine.

Together, they unpack what NAD+ really is and why it has become one of the most discussed interventions in longevity and performance optimization. Iain explains how NAD+ supports cellular function, mitochondrial health, cognitive performance, energy production, and recovery, making it a key component of many modern longevity protocols.

Iain shares his personal journey from the high-pressure world of global finance into longevity medicine after experiencing severe burnout and discovering the potential of NAD+ therapy. He explains how that experience led him to build NAD Clinic Group with a strong focus on clinical protocols, medical oversight, education, and making longevity interventions more accessible to a broader population.

A major focus of the discussion is the importance of evidence-based longevity rather than hype-driven wellness trends. Iain explains why regulation, medical supervision, and personalized protocols are essential in a rapidly growing industry where misinformation, aggressive marketing, and unproven interventions have become increasingly common.

The conversation also explores the future of NAD+ delivery, including IV therapy, subcutaneous administration, and a new inhaled pulmonary delivery system designed to improve convenience, absorption, accessibility, and global scalability. Iain discusses how innovative delivery methods could help democratize longevity medicine by reducing costs and making interventions available beyond specialized clinics.

The discussion also covers cellular health, mitochondrial function, metabolic wellness, burnout recovery, smoking cessation, hospitality-based longevity clinics, education for healthcare professionals, and the rapidly expanding longevity ecosystem across the GCC and MENA region. Iain shares why he believes the future of healthcare lies in prevention, optimization, and helping people take greater responsibility for their long-term health before disease develops.
