Full Show notes: https://bengreenfieldlife.com/magteinpodcast Can a specific form of magnesium reverse brain age by 7.5 years in six weeks? That’s what was observed in controlled human trials led by this episode’s podcast guest, Dr. Guosong Liu, an MIT-trained neuroscientist who spent over two decades at the Picower Institute studying how the brain forms and stores memory. Most magnesium supplements do not reach the brain in meaningful amounts. Magnesium L-threonate does, because binding magnesium to L-threonate improves its ability to cross the blood-brain barrier. Once inside, it supports synaptic density and N-methyl-D-aspartate receptor activity, which are directly involved in learning, memory formation, and cognitive performance. We also get into: - Why higher brain magnesium levels are linked to stronger cognitive performance - Human data on executive function, memory, and age-related decline - How magnesium shifts sleep architecture toward deeper, more restorative stages - How to approach dosing, timing, and delivery formats 00:00 Introducing Dr. Liu, neuroscientist 06:16 Pairing supplements with activities 08:26 Explaining synaptic plasticity and PTSD therapy 11:47 Discovering magnesium for brain research 14:21 Discovering magnesium's brain benefits 20:17 Magnesium and brain health 20:57 Magnesium bioavailability explained 27:15 First human clinical trial results 29:42 Magnesium L-Threonate research findings 33:25 Executive function and memory boost 35:13 Magnesium and intracellular function 38:39 Magnesium and sleep misconceptions 41:41 Magnesium's impact on sleep and stress 45:57 Threonine’s role in brain function 49:36 Affiliate links and product transparency .📲 Check out my FREE Top Health Community! - https://joinlifenetwork.com 💊Shop My Curated Marketplace of Vetted Products! - https://shoplifemarket.com 🏋️Sign up for a FREE Coaching Call! - https://jointriumphcoaching.com 📩 Check out my FREE newsletter! - https://bengreenfieldlife.com/newsletter/ 🔗My Website: https://bengreenfieldlife.com/ 🔗My Podcast: https://bengreenfieldlife.com/podcast/ 🔗My Books: https://shopbengreenfieldlife.com/collections/books Connect with me: ⬇️ Instagram https://www.instagram.com/bengreenfieldfitness/ Facebook https://www.facebook.com/BGFitness X https://twitter.com/bengreenfield TikTok https://www.tiktok.com/@bengreenfield
