Matt's Thanksgiving Message

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.

Happy thanksgiving from the Optispan Team!

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?

Creatine is being called a "cognitive super-drug" that feels like "speed without the speed." Influencers are telling you to mega-dose 20 grams a day for brain power, bone health, and more. But what does the science actually say?In this episode, we go beyond the hype and fact-check the wildest creatine claims taking over the internet. I break down the real evidence on mega-dosing, and put the cognitive benefits to the testI react to clips from Paul Saladino, Jeff Cavalier, Rhonda Patrick, and Dave Asprey to separate proven fact from marketing fiction.

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.Key Topics & Timestamps:00:00 - Introduction00:52 - Brad's Background02:47 - Starting the YouTube Channel & Philosophy on Science Communication07:39 - The Rigor of Clinical Data vs. Misinformation10:14 - Admitting Mistakes in Public (Resveratrol, Metformin)14:40 - Funding and Designing the Rapamycin Clinical Trial19:25 - Rapamycin Trial Results Submitted & Plans for a PhD23:28 - Preventative Care: New Zealand vs. US Healthcare Systems27:59 - The Vitamin D Debate: To Test or Not to Test?35:18 - Trust in Medical Guidelines & The Hormone Replacement Therapy Controversy43:42 - The Problem with Biological Age Clocks46:22 - Patient-Centered Care: Inform vs. Decide in Medicine49:49 - How to Judge the Quality of a Clinical Trial (CONSORT)53:44 - Risk vs. Benefit: When Should We Prescribe Preventative Drugs?58:05 - GLP-1 Agonists (Ozempic) and SGLT2 Inhibitors in Practice01:02:00 - Brad's Personal Use of an SGLT2 Inhibitor01:05:38 - The State of Longevity Research: How Much Do We Really Know?01:08:34 - Closing RemarksDISCLAIMER: The information provided on the Optispan podcast is intended solely for general educational purposes and is not meant to be, nor should it be construed as, personalized medical advice.

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.
