Dr. Henry Mahncke reveals how an NIH-funded study showed brain training reversed brain aging markers by 10 years, why speed-based training is uniquely effective, and the future of brain health interventions.Dr. Henry Mahncke, CEO of Posit Science and creator of BrainHQ, discusses the groundbreaking INHANCE study that used PET scans to show brain training can reverse brain aging by 10 years. In this wide-ranging conversation, Dr. Mahncke explains how their adaptive brain training exercises increase acetylcholine—a crucial neurochemical that declines with age and is depleted in Alzheimer's disease. He addresses common criticisms of brain training, explaining why speed and accuracy training is fundamentally different from memorization exercises, and shares surprising insights including why Tom Brady uses brain training. We discuss optimal dosing (30 minutes daily works well), the role of sleep in brain plasticity, supplementation with compounds like phosphatidylcholine, and whether this should be a lifelong practice. Dr. Mahncke makes the case that we're at the beginning of a "brain health revolution" where maintaining cognitive function should be as routine as physical exercise🌐Links in this video Brain HQ website https://www.brainhq.com/ The trial on clinical trials https://clinicaltrials.gov/study/NCT04149457 Effects of Computerized Cognitive Training on Vesicular Acetylcholine Transporter Levels using [18F]Fluoroethoxybenzovesamicol Positron Emission Tomography in Healthy Older Adults: Results from the Improving Neurological Health in Aging via Neuroplasticity-based Computerized Exercise (INHANCE) Randomized Clinical Trial https://games.jmir.org/2025/1/e75161Seeking Health supplements: 10% discount code Richard10 https://crrnt.app/SEEK/-dm0MyrQ, Histamine Nutrients https://crrnt.app/SEEK/EpM7paAOAX3 Life Astaxanthin 20% discount code MODERN20 https://tinyurl.com/2t3w26nwhttps://www.choosemuse.comStemregen 15% discount Code MODERN https://tinyurl.com/45z968yr (Only available in the US)Renue by Science all 10% discount with code MHS https://renuebyscience.com/ Nuchido Time+ 20% discount of first purchase with code MODERN20 https://nuchido.com/MODERNIf you would like to support our channel please consider signing up on patreon https://patreon.com/ModernHealthspanYou can also find us on YouTube at https://www.youtube.com/c/modernhealthspan

Dr. John Cramer, 92-year-old nuclear physicist, discusses participating in the first mitochondrial transplant trial for aging and his longevity theory.Dr. John Cramer is a 92-year-old emeritus professor at the University of Washington who has spent decades researching nuclear physics and quantum mechanics. Now, he's turned his attention to longevity, and he's not just theorizing. Dr. Cramer is participating in Mitrix's groundbreaking mitochondrial transplantation trial, which aims to replace damaged mitochondrial DNA with healthy versions grown in bioreactors.In this conversation, Dr. Cramer explains why he believes mitochondrial dysfunction is the root cause of aging, not just another hallmark. He discusses how energy depletion cascades into all other aging symptoms, why previous interventions like telomere extension haven't delivered, and what markers will be tracked throughout his trial. He also shares his personal longevity protocol, including rapamycin, senolytics, and hyperbaric oxygen therapy.This is one of the first detailed discussions of autologous mitochondrial transplantation for aging in humans.🌐Links in this video Mitrix Bio website https://mitrix.bioSeeking Health supplements: 10% discount code Richard10 https://crrnt.app/SEEK/-dm0MyrQ, Histamine Nutrients https://crrnt.app/SEEK/EpM7paAOAX3 Life Astaxanthin 20% discount code MODERN20 https://tinyurl.com/2t3w26nwhttps://www.choosemuse.comStemregen 15% discount Code MODERN https://tinyurl.com/45z968yr (Only available in the US)Renue by Science all 10% discount with code MHS https://renuebyscience.com/ Nuchido Time+ 20% discount of first purchase with code MODERN20 https://nuchido.com/MODERNIf you would like to support our channel please consider signing up on patreon https://patreon.com/ModernHealthspanYou can also find us on YouTube at https://www.youtube.com/c/modernhealthspan

Mayo Clinic's Dr. Sundeep Khosler discusses findings from the first major randomized controlled trial of senolytics in humans, revealing why cellular aging varies dramatically between individuals and what this means for longevity interventions.Dr. Sundeep Khosler, a physician-researcher at the Mayo Clinic, leads some of the first human clinical trials testing senolytics for aging and age-related diseases. In this conversation, he shares critical findings from their 60-person randomized controlled trial that challenge assumptions about how we age at the cellular level.The study revealed that senescent cell burden varies dramatically between individuals, with significant implications for who might benefit from senolytic interventions. While overall results showed modest improvements in bone formation markers, women with the highest senescent cell burden (measured through blood biomarkers) showed dramatic 60% improvements—suggesting aging interventions may require personalized approaches rather than universal protocols.Dr. Khosler discusses the development of blood-based biomarkers for measuring senescent cell burden, explains why age 70 appears to be a critical threshold, and addresses the gap between promising animal studies and human translation. He provides evidence-based guidance on what people can do now, explains why he doesn't recommend current senolytics outside clinical trials, and discusses FDA-approved medications that may impact cellular aging as secondary benefits.This interview offers a balanced, nuanced perspective on where senolytic research actually stands, moving beyond hype to understand both the promise and limitations of targeting senescent cells for healthspan.🌐Links in this video Dr Khosla's page at the Mayo Clinic https://www.mayo.edu/research/faculty/khosla-sundeep-m-d/bio-00078126Effects of intermittent senolytic therapy on bone metabolism in postmenopausal women: a phase 2 randomized controlled trialhttps://pubmed.ncbi.nlm.nih.gov/38956196/Seeking Health supplements: 10% discount code Richard10 https://crrnt.app/SEEK/-dm0MyrQ, Histamine Nutrients https://crrnt.app/SEEK/EpM7paAOAX3 Life Astaxanthin 20% discount code MODERN20 https://tinyurl.com/2t3w26nwhttps://www.choosemuse.comStemregen 15% discount Code MODERN https://tinyurl.com/45z968yr (Only available in the US)Renue by Science all 10% discount with code MHS https://renuebyscience.com/ Nuchido Time+ 20% discount of first purchase with code MODERN20 https://nuchido.com/MODERNIf you would like to support our channel please consider signing up on patreon https://patreon.com/ModernHealthspanYou can also find us on YouTube at https://www.youtube.com/c/modernhealthspan

Could a decline in "plasmalogens" be a missing link in Alzheimer's and aging? Dr. Peter Meikle reveals why this critical brain lipid drops as we age and the surprising foods that might help restore it.In this interview, we sit down with Dr. Peter Meikle, Head of the Metabolomics Laboratory at the Baker Heart and Diabetes Institute, to explore the critical role of plasmalogens in human health. Plasmalogens are unique phospholipids that act as powerful antioxidants, protecting our cell membranes from oxidative stress. Dr. Meikle explains how plasmalogen levels naturally decline with age and why this drop is strongly associated with Alzheimer's disease, heart disease, and fatty liver.We dive deep into the genetic connection, specifically how the ApoE4 gene impacts these lipids, and discuss the results of mediation analyses that suggest a causal link to neurodegeneration. Finally, Dr. Meikle shares practical advice on how to boost your levels, debating the trade-offs of dietary sources like eggs and red meat versus supplements like krill oil and shark liver oil, and outlines the future of synthetic plasmalogen therapy.🌐Links in this video Dr Meikle's page at Baker https://baker.edu.au/research/staff/peter-meiklePelagic AI https://pelagicai.it/Juvanescence https://juvlabs.comSeeking Health supplements: 10% discount code Richard10 https://crrnt.app/SEEK/-dm0MyrQ, Histamine Nutrients https://crrnt.app/SEEK/EpM7paAOAX3 Life Astaxanthin 20% discount code MODERN20 https://tinyurl.com/2t3w26nwhttps://www.choosemuse.comStemregen 15% discount Code MODERN https://tinyurl.com/45z968yr (Only available in the US)Renue by Science all 10% discount with code MHS https://renuebyscience.com/ Nuchido Time+ 20% discount of first purchase with code MODERN20 https://nuchido.com/MODERNIf you would like to support our channel please consider signing up on patreon https://patreon.com/ModernHealthspanYou can also find us on YouTube at https://www.youtube.com/c/modernhealthspan
