ing biological age tests.In this episode, Dr. Matt cuts through the noise to explain what ageing clocks actually are, what they measure, and more importantly, what they DON'T. You'll learn why that $500 direct-to-consumer test is likely giving you meaningless noise, why seeing a drop in your "biological age" is often a statistical illusion, and what to do if your doctor recommends one.By the end, you'll understand ageing clocks better than 95% of the supposed experts and influencers out there. You'll also learn about the type of clock that shows real promise for personalized health today.This video was produced by One Billion Media, an agency that specializes in YouTube virality for health brands and experts.

This podcast episode is part three of a travel series where Matt recounts his recent trips to longevity and healthspan conferences in Geneva, Chicago, and Mauritius. He shares his experiences with jet lag, workouts, and the contrasting cultures of these events, from the more "alternative medicine" feel of the Geneva summit to the more scientifically-grounded Mauritius conference. A major theme is his critique of the current state of the longevity field, where he advocates for evidence-based approaches and calls out what he sees as misinformation, specifically regarding the overhyping of peptides, stem cells, and the misuse of epigenetic "aging clocks."This video was produced by One Billion Media, an agency that specializes in YouTube virality for health brands and experts.

Longevity scientist Dr. Andrew Steele sits down with Dr. Matt Kaeberlein to make the provocative case that aging should be treated as humanity's greatest challenge, even bigger than climate change. In this deep conversation, they explore why two-thirds of all deaths are caused by aging, the cutting-edge science that's already extending healthy lifespan in animals, and what it would really mean to add decades of vitality to human life. From CRISPR gene therapies to senescent cell clearance, from the ethics of radical life extension to practical steps you can take today, this is an unflinching look at whether we can (and should) slow down aging itself.Timestamps00:00 – Why Aging Is the Biggest Problem We’re Not Solving01:33 – Is Aging Actually Fixable?

In this in-depth conversation, Dr. Brad Stanfield sits down with Dr Matt Kaeberlein to discuss his journey from a primary care physician in New Zealand to a leading voice in the evidence-based longevity space. We cover the launch and philosophy behind his YouTube channel, the challenges and exciting results of his self-funded rapamycin clinical trial, and his critical perspective on supplements, medical guidelines, and the future of aging research.
Dr. Stanfield provides a unique clinician's viewpoint on hot topics like GLP-1 agonists (Ozempic), SGLT2 inhibitors, vitamin D testing, and the pitfalls of biological age clocks. We also dive into a spirited debate on the role of medical societies, the balance between risk and benefit in prescribing medications, and why he believes the field of longevity is still in its early stages of discovery.

I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it.On this podcast I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these episodes helpful!

In this podcast, I sit down with Dr. Jon Berner to explore two of the most promising yet misunderstood therapeutic agents: Lithium and Rapamycin.
We begin with a groundbreaking discussion on Lithium, moving far beyond its traditional use in psychiatry. We break down the recent landmark study in Nature that positions lithium as a potential powerhouse for combating Alzheimer's disease, delve into the different salts (orotate vs. carbonate), and discuss who might benefit, who should be cautious, and the practical realities of dosing and side effects.
In the second half, we shifted to Rapamycin, focusing on an exciting new preprint study on its use for Chronic Fatigue Syndrome (ME/CFS). We explore the compelling "hyperinflammatory" hypothesis for ME/CFS and long COVID, question whether current off-label dosing is too low, and debate the classic mTORC1 vs. mTORC2 model. The conversation also covers radical new ideas like high-dose pulse therapy, its potential use in IVF, and the powerful synergy of combining rapamycin with ketamine for treatment-resistant conditions.
Throughout, we tackle the larger themes of personalized medicine, the limitations of the FDA, and how new AI-driven tools are beginning to map the complex, N-dimensional biochemical space of human health.

They pull back the curtain on what a truly evidence-based, scientific approach to longevity medicine looks like, moving beyond the hype and "snake oil" to focus on rigorous diagnostics, personalized interventions, and the critical collection of high-quality data.In this episode, they delve into the comprehensive 6+ hour diagnostic workup I am about to undergo, discuss the hierarchy of interventions (from lifestyle as the foundation to the careful use of pharmaceuticals), and debate the role of supplements, peptides, and more experimental therapies. This is a masterclass in the practical application of healthspan medicine from leading clinicians in the field.This video was produced by One Billion Media, an agency that specializes in YouTube virality for health brands and experts.

Dr. Younggren walks us through what really happens during TPE, which biomarkers shift the most, and who might benefit the most.This video was produced by One Billion Media, an agency that specializes in YouTube virality for health brands and experts.

Just back from the tour of the longevity world! In this episode, we discuss my recent travels to two major conferences: the high-end Longevity Investors Conference in Gstaad, Switzerland, and the academic GJAM Conference in Jena, Germany.
We unpack the stark contrasts between these two worlds, from the venues and treatment of attendees to the fundamental divides in how people perceive and practice "longevity." I share my key takeaways on the growing chasm between real science and snake oil, the "apologist" perspective, and why I believe the term "Longevity Medicine" is already developing a bad reputation.
We also cover:
The ethical problem with using biological age clocks in clinical practice today.
My experience going through the comprehensive health assessment at the Years Clinic in Berlin.
Surprising VO2 Max results and a hilarious (and slightly alarming) story about getting a full-body MRI in Germany.
The disconnect between academic geroscience and the biohacking community.
My thoughts on the future of validated biomarkers.

Alzheimer’s is often talked about but rarely understood in full. For decades, most research has focused on amyloid plaques, but what if that’s only part of the story? In this deep-dive, Dr. Cory, from the Institute for Systems Biology explains a new way of looking at Alzheimer’s: It is not simply a plaque problem, but as a breakdown in the brain’s “debris management” system, especially how it handles cholesterol. This perspective connects the dots between genes like ApoE4, the role of microglia, and everyday factors like sleep and stress. It also helps explain why current drugs give mixed results, and what might actually work in the future. Dr. Cory also shares practical insights on prevention and what a new era of treatment could look like .This video was produced by One Billion Media, an agency that specializes in YouTube virality for health brands and experts.

Most people take supplements without ever checking if their body actually needs them. Is that smart… or just expensive guesswork?
In this podcast, Dr. Matt Kaeberlein sits down with Ryan Ware to unpack the truth about supplements, the rise of AI in medicine, and how people are consuming health information today. From internet “gurus” to tools like ChatGPT, they explore where people are searching for health answers, and whether those answers are truly helping or quietly harming.
Along the way, they share critical reflections on the wellness industry’s blind spots, the limitations of blood tests, and what smarter, evidence-based health decisions really look like.
Join the conversation to find out what really matters for your health, and what’s just hype!
