Longevity Roadmap

In this conversation, Dr. Tara Walker discusses the fascinating topic of adult neurogenesis, the brain's ability to produce new neurons throughout life.

She explains how this process is crucial for cognitive function and how it declines with age.

The discussion highlights the significant role of exercise in boosting neurogenesis and introduces selenium as a key factor in this process.

Dr. Walker also explores the implications of her research for cognitive health, particularly in the context of neurodegenerative diseases, and the potential therapeutic strategies that could arise from understanding neurogenesis better.

Sleep is the secret weapon for a longer, healthier life—and Dr. Michael Breus is here to show you how to use it.

In this episode of Longevity Roadmap, Buck Joffrey dives deep into the science of sleep with the world-renowned sleep doctor himself. Discover why sleep is the third pillar of longevity, how REM sleep and deep sleep fuel physical and emotional restoration, and what your chronotype reveals about your ideal sleep patterns.

From the effects of sleep deprivation on metabolism and aging to natural sleep tips, supplements, and cutting-edge alternatives to CPAP machines for sleep apnea, this conversation is packed with actionable advice to boost your sleep quality and your longevity.

What if targeting a single cellular pathway could slow aging and boost immunity?

Dr. Joan Mannick, a leading voice in aging science, reveals how mTOR inhibitors may be the future of longevity therapeutics. From her early inspiration to groundbreaking clinical trials, Dr. Mannick explores the role of mTOR in aging, immune response, and antiviral immunity. Learn how selective mTOR inhibition could extend healthspan without compromising muscle mass, improve vaccine response in older adults, and unlock new possibilities in clinical longevity.

Vitamin D is more than a vitamin—it's a hormone that influences everything from your immune system to cardiovascular health, cognition, and longevity. In this conversation, Dr. Michael Holick breaks down the science of vitamin D synthesis, the truth about sun exposure vs. supplements, and why vitamin D deficiency is far more common—and more dangerous—than most people realize.

You'll learn how skin pigmentation, UVB exposure, and supplementation protocols impact your vitamin D levels, and why D3 is more effective than D2. Dr. Holick also dives into mood, cognition, and the controversial role of vitamin D in chronic disease and COVID outcomes.

With dosage guidelines by age and weight, plus practical advice on avoiding vitamin D toxicity, this episode is a masterclass on one of the most important—yet misunderstood—nutrients in health and longevity.

Is your memory decline normal—or something more? Clinical neuropsychologist Dr. Mitchell Clionsky breaks down what healthy aging looks like from a cognitive perspective and where concern might be warranted. He introduces the Memory Orientation Screening Test (MOST)—a powerful yet quick tool to assess cognitive health—and shares insights from decades of evaluating memory, dementia, brain injuries, and CTE. From preventive strategies that could reduce dementia risk by nearly 50%, to how technology is transforming neuropsychology, this conversation is a must-watch for anyone invested in long-term brain health.

What if your body already had everything it needs to heal itself—naturally?

In this episode, neurophysiologist and stem cell researcher Dr. Christian Drapeau breaks down the science of stem cell therapy, explaining how adult stem cells, embryonic stem cells, and exosomes play a central role in regenerative medicine and longevity.

Discover how aging affects the body's ability to mobilize stem cells, how injury signals guide them, and why immune system function is tightly linked to stem cell activity.

Is it possible to rejuvenate the immune system as we age? In this episode, Dr. Alessio Lanna breaks down the science of immune aging, focusing on the critical role of T cells, telomere shortening, and senescence. He explains how T cells lose their effectiveness over time—and shares emerging research on how intercellular telomere transfer and the ESMAC complex may help reverse immune senescence. Learn how pharmacological interventions could unlock new possibilities for health, longevity, and immune rejuvenation.

Are your mitochondria aging faster than you are?

In this episode, Dr. Mark Tarnopolsky breaks down the central role of mitochondria in aging, longevity, and overall metabolic health. Learn how mitochondrial dysfunction drives age-related decline, including neurodegenerative diseases, and what you can do about it.

From the paradox of oxidative stress to the risks of overusing antioxidants, this conversation unpacks what actually supports mitochondrial health—including a clinical "mitochondrial cocktail" targeting multiple aging pathways.

Dr. Tarnopolsky also explains how exercise, nutrition, VO2 max, and exokines impact your healthspan, plus why most therapeutics miss the mark.
