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.

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.
