In this episode, David and Matt ask the questions we all want to ask. Could peptides such as humanin help protect the brain against Alzheimer’s disease? Can they accelerate healing, repair damaged tissues, ease arthritis, or improve muscle and gut health? Might they eventually offer new ways to treat age-related diseases? They also separate promising science from hype, examining which peptides have credible evidence from human studies, which remain experimental, and what we know about their safety. The conversation also looks at the first FDA-approved medicine designed to target mitochondria. __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

But can they really help us age better? In this episode, David and Matt dive into the rapidly evolving science of peptides—and their potential to transform longevity medicine. They explore promising compounds like GHK-Cu, MOTS-c, Epitalon, and apelin, examining what the research reveals about cellular repair, stem cells, telomeres, and the hallmarks of aging. Along the way, David separates scientifically promising treatments from unproven hype and unpacks the potential benefits, risks, and unanswered questions surrounding these increasingly popular compounds. As David puts it, “We're going to have going forward a bunch of different peptides that hopefully will help us with our longevity.” __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

Could they also extend lifespan? In this episode, David and Matt look at the emerging science behind that question. They examine a recent study in which semaglutide extended lifespan in female mice, evidence that GLP-1s may influence multiple hallmarks of aging, plus early human research examining biological aging. They also explore how these drugs work, the potential role of the brain, the promise and unanswered questions around microdosing, and what the next generation of GLP-1 therapies could mean for longevity medicine. As David puts it, this class of drugs “might be the world’s first effective longevity medicines."  __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

Dr. Sinclair explains how diet affects key biological processes tied to metabolism, health, and longevity. Dr. Sinclair breaks down what sugar does inside the body, including glycation - the process by which sugar attaches to proteins and disrupts their function. The conversation also explores why inflammation rises with age, how the gut microbiome changes over time, and why our ability to sense and respond to nutrients can decline as we get older. Most importantly, Dr. Sinclair explains what we can do about it - from reducing dietary drivers of inflammation and excess sugar to supporting gut health and the nutrient-sensing pathways linked to longevity.  __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

They break down key drivers - or “hallmarks” - of aging, including mitochondrial dysfunction, stem cell exhaustion, and declining communication between cells, and explain how these changes can affect energy, inflammation, and the body’s ability to repair itself. They also explore practical strategies including exercise, cold exposure, and molecules such as berberine, curcumin, metformin, and resveratrol, alongside emerging research into mitochondrial replacement and stem cells. Along the way, they tackle intriguing questions: When does biological aging begin? Why can identical twins age at different rates? Why does energy decline with age? And what can we do today to stay healthier for longer? __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

Drawing on evolutionary biology and the latest research, Dr. Sinclair traces physical activity back millions of years, explaining how humans evolved for endurance, why modern sedentary life creates a profound mismatch with our biology, and how exercise activates ancient cellular pathways involved in repair, resilience, metabolism, and longevity. Dr. Sinclair breaks down what happens inside the body when we exercise, including the molecular responses that help us adapt to stress and influence the brain, immune system, metabolism, cardiovascular health, and even the way our cells age. He also tackles some of the biggest questions in exercise science: Can exercise offset sitting all day? Do we compensate for calories burned during exercise? Why did humans evolve such extraordinary endurance? And could exercising with others provide benefits beyond physical fitness? From our evolutionary past to the molecular machinery inside our cells, this episode reveals why movement is so deeply embedded in human biology – and why staying active may be one of the most powerful ways to keep that biology working as we age. __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.

Drawing on the latest research, Dr. Sinclair explains why exercising for longevity isn’t the same as training for peak athletic performance – including how much exercise you really need, which types matter most as you age, and whether more exercise is always better. He also breaks down the key fitness metrics for longevity – including VO2 max, grip strength, resting heart rate, and heart rate variability (HRV) – and why cardiorespiratory fitness may predict mortality more strongly than smoking, diabetes, or hypertension. Lastly, Dr. Sinclair tackles some of the most common questions about exercise science: What’s the best time of day to work out? Should you drink coffee beforehand? Should men and women train differently? How should exercise change as you age? Whether you're just getting started or already exercise regularly, this episode offers a practical, evidence-based guide on what to do to stay healthier for longer.     __________________________________________ Partners of the Lifespan show help us keep this program freely available as an educational resource while also supporting medical research.
