Drawing on thousands of liver scans, he shares what his team has observed in people whose blood markers appeared normal despite signs of fatty liver on imaging, and explains how tools such as FibroScan can reveal liver fat, stiffness, and fibrosis. Dave and Siggi go deep into triglycerides, cholesterol, insulin resistance, brain fog, weight gain, bi

Novo Nordisk Eyes Hair-Loss Market in Consumer-Health Expansion Novo Nordisk, the company behind Ozempic and Wegovy, is exploring hair loss as one of several possible areas for future expansion, alongside menopause and addiction. The company has not announced a hair-loss drug, clinical trial, acquisition, or partnership, but Chief Scientific Officer Martin Holst Lange pointed to the category during the company's 2026 Capital Markets Day. Host Dave Asprey breaks down why hair loss makes strategic sense for a company already deeply involved in endocrine biology, how emerging treatments are moving beyond traditional options like minoxidil and finasteride, and why sudden shedding during rapid GLP-1 weight loss may be telogen effluvium rather than traditional pattern baldness. Sources: https://www.bloomberg.com/news/articles/2026-09-22/ozempic-maker-novo-looks-to-target-hair-loss-in-consumer-push https://www.novonordisk.com/investors/capital-markets-day-2026.html https://www.irishexaminer.

Back again with one of the best episodes we've done on the channel. So good that we had to play it once more for you! Today you’ll meet Robert Waldinger, M.D., who leads an extraordinary scientific study on happiness that’s still going strong after eight decades. The study set out to understand human health by what made people thrive.Since 1938, the Harvard Study of Adult Development has tracked two groups of men and their families with the goal of discovering what really makes for a good life. Along the way, thousands of questions were asked, and hundreds of measurements were taken—from brain scans to blood work. Three strong themes emerged from the study: Social connections are really good for you. Loneliness kills.It’s the quality of your close relationships that matters.Good close relationships don’t just protect your body, they protect your brain.Dr. Waldinger combined those lifelong case studies with modern psychological research in his new book, co-authored

Spirulina contains compounds including phycocyanin and superoxide dismutase that Catharine believes can support mitochondrial function, antioxidant defenses, cellular energy, and brain health, while chlorella is used

Back with another all-time classic. Teal's is one of those episodes I keep going back to because it was just that good. Now more than ever, we need to ask ourselves: what is the role of Ego? Do we need to worry about AI killing us? Is there hope for the future of our species?These are just a few of the big questions you’ll tackle in this enlightening and esoteric episode re-run. I’m joined by Teal Swan, a thought leader, bestselling author, and international speaker who is on a mission to reduce human suffering. After a challenging upbringing, Teal emerged with a unique ability to talk about psychology, shadow work, and the nature of our world. Teal shares the unusual and special way she sees the world. We talk about her ESP powers, how to identify a narcissist, and her favorite dimensions. We also get into the divine masculine vs. the divine feminine, the nature of ego, and how to build trust in the world and others. 00:00 — Trailer00:18 — Intro6:12 — Understanding Narcissism13:20 — AI and Spiritua

Dr. Michael Leon on Smell Training, Memory, Sleep, Alzheimer’s Risk, and Brain Longevity Your sense of smell may reveal more about your brain health than you realize, and stimulating it while you sleep may improve memory, sleep quality, and cognitive function. **Visit https://memoryair.com/ and use code DAVE15 for 15% off. **Host Dave Asprey sits down with Dr. Michael Leon, Professor Emeritus of Neurobiology and Behavior at UC Irvine and one of the world’s most cited scientists, to explore why smell may be one of the most overlooked tools for brain health and longevity. Dr. Leon explains why the olfactory system has unusually direct access to the brain’s memory and emotional centers, why smell often declines alongside memory after age 60, and why reduced olfactory function has been associated with Alzheimer’s disease, cognitive decline, depression, and increased all-cause mortality. They also discuss how COVID, chronic congestion, pollution, stress, and aging can i

Carolina Reis de Oliveira on Reversing Skin Age, Menopause, GLP-1 Skin, and the Science of Senescent Cells Your skin is likely biologically older than you are, but new research suggests some of that aging may be reversible. **For Dave’s listeners only, visit oneskin.co/Dave  for exclusive early access to the OS-01 Face Rich Cream!**Host Dave Asprey sits down with Carolina Reis de Oliveira, PhD, CEO and co-founder of OneSkin. Carolina holds a PhD in stem cell biology and tissue engineering, is a co-inventor of five patents, and has co-authored numerous scientific publications. She and her team are studying skin longevity by targeting one of the central drivers of aging: the accumulation of senescent cells.  They break down why skin loses its ability to hold water as you age, and why that process can accelerate dramatically during perimenopause and menopause.

Sea Squirt Plasmalogens Show Brain And Aging Benefits In Old Mice Aged mice given purified plasmalogen supplements showed better memory performance, healthier synaptic structure, lower neuroinflammation, and increased signaling tied to neurite growth and synapse development, with treated mice even growing thicker, darker, glossier hair. Plasmalogens are specialized lipids concentrated in cell membranes and the brain that tend to decline with age and neurodegenerative disease, making them an intriguing target for cognitive longevity. Host Dave Asprey breaks down why membrane composition matters for brain signaling, mitochondrial function, and inflammation, while stressing that this remains mouse research from 2022 and does not mean eating sea squirts or taking an unproven plasmalogen supplement will reproduce the same effects in humans. Sources: https://www.sciencedaily.com/releases/2026/09/260902234518.htm https://doi.org/10.3389/fmolb.2022.815320 ~~ Apple Watch Series 12 Adds Mo

Raw Garlic "Ultimate Biohack" Trend Faces Scientific Scrutiny Raw garlic has gone viral as a morning ritual, with fans crushing a clove, mixing it with honey, and crediting it with everything from lower cholesterol and better insulin sensitivity to cleared acne, eliminated brain fog, and colds cured within 24 hours. The biochemistry behind the trend is real: garlic contains no allicin until it's crushed or chopped, which mixes an enzyme with a sulfur compound to form the active compound, and letting it sit for ten to fifteen minutes before cooking preserves more of that activity. Host Dave Asprey separates what the human data actually supports, modest blood pressure and cholesterol effects, real antimicrobial properties, and a genuine bleeding-risk caution for anyone on blood thinners, from the unproven parasite-cleanse and brain fog claims driving the trend online, drawing on his own EEG tracking to challenge the cognitive benefit narrative directly. Sources: https://nypost.com/2026/09/01/heal

The 3 "Longevity Drugs" That Fail the Data, and 4 Repurposed Ones Worth Considering  Back with another solo episode, this one on Big Pharma!
