The Optispan Podcast with Matt Kaeberlein

• Scientist Reacts: Why Megadosing Creatine Is A Waste Of Time

  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. Discover the simple, science-backed creatine protocol that actually works, and save your money (and your gut) in the process.This video was produced by One Billion Media, an agency that specializes in YouTube virality for health brands and experts.

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!
