The Longevity Blueprint: How to Live Younger, Longer w/ Jeffrey Gladden, MD

·55 min·5 clips

A cardiologist diagnosed as 'normal for your age' refused to accept decline and discovered a hidden thyroid mutation.

This episode features host Evan Trans (Detective Ev) interviewing Dr. Jeffrey Gladden, a board-certified interventional cardiologist and founder of Gladden Longevity. Dr. Gladden shares his personal health journey that led him from conventional cardiology to longevity medicine. He experienced exhaustion, weight gain, anxiety, depression, and brain fog in his fifties, which conventional tests deemed normal for his age. Dr. Gladden discovered he had subclinical hypothyroidism, a DIO2 gene mutation affecting thyroid conversion, and hormonal depletion. Correcting these with specific thyroid medications, testosterone, and DHEA restored his energy and physique. He also addressed neurotransmitter imbalances linked to poor methylation genetics using supplements like SAM-e and folinic acid. His father's dementia and his own brain fog motivated his deep dive into functional and integrative medicine, a process that took him two and a half years. He explains that aging is an exponential, not linear, process, and combating it requires an exponential strategy beyond basic diet and exercise. Dr. Gladden's longevity framework addresses five interconnected areas: life energy (psycho-spiritual health), the biological hallmarks of aging, organ system health, physical performance, and environmental design. He emphasizes the critical importance of the psycho-spiritual circle, stating it binds all others and directly impacts physiological responses to treatments. A surprising insight is that a parasympathetic, relaxed state can improve outcomes from regenerative medical procedures. Dr. Gladden argues that the greatest return on investment comes from maintaining physiologic youthfulness to extend one's period of high impact and opportunity in life. His ultimate vision is for people to have a "30-year-old body and a 300-year-old mind" at age 100, combining peak physicality with accumulated wisdom. The conversation is educational and inspirational, blending personal narrative with detailed medical and physiological concepts. The tone is conversational and passionate, with the host and guest sharing their own health transformations as motivating examples. Listeners interested in advanced health optimization, anti-aging science, and moving beyond conventional wellness approaches would find this episode compelling. Those seeking quick fixes or skeptical of functional medicine and genetic testing might find the content less relevant.
