Your relationships are reshaping your biology in ways that diet and exercise alone cannot fix, and the science behind it will change how you think about longevity, metabolism, and what it actually means to be healthy. Watch this episode on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR  Host Dave Asprey sits down with Dr. Molly Maloof, a physician and one of the most innovative voices in personalized medicine, functional medicine, and human performance. Since 2012, she has advised or consulted for over 50 companies across digital health, consumer health, and biotechnology. She pioneered a course on healthspan at Stanford University and founded Adamo Bioscience, a company dedicated to unlocking the science of love as a pathway to healing and human connection. Dr. Maloof brings a rare combination of clinical depth, biohacking credibility, and entrepreneurial range to one of the most overlooked conversations in longevity.  

Most guys over 40 rely on coffee just to survive the day, completely unaware that they are pushing their brains into a frantic, high-stress state that actually destroys deep focus and accelerates cognitive decline. In this video, I reveal the science behind why caffeine is failing you and introduce you to a 4,000-year-old amino acid used by monks to achieve effortless, sustained attention. I'll walk you through the optimal 2:1 biohacking stack that flips your coffee from a nervous, jittery habit into a highly controlled focus weapon. You'll learn exactly how to dose it, when to take it, and how to stop the hidden lifestyle habits that are secretly sabotaging your nervous system, so you can reclaim the mental edge you had in your twenties and stay competitive.Thank you to our sponsors!-HeartMath | Go to https://www.heartmath.com/dave to save 15% off-The One Device | Use code DAVE for $10 off at theonedevice.com/dave-iRestore | Reverse hair loss at www.irestore.com/DAVE and get exclusiv

One Creatine Dose Kept Sleep-Deprived Brains 12% Sharper A randomized, double-blind crossover trial kept 29 healthy adults awake for 21 hours straight ... half the time on a single moderate dose of creatine (~14g), half the time on placebo ... and found the creatine group held on to up to 12% more cognitive performance across logic, reaction time, and language processing. Host Dave Asprey breaks down why sleep deprivation is just another form of brain energy stress, how creatine's phosphate-buffering mechanism stabilizes ATP in the prefrontal cortex under pressure, and why this changes how he thinks about red-eye flights and all-nighters. Vegetarians and women showed the largest effects ... your baseline diet sets your ceiling. Sources: https://pubmed.ncbi.nlm.nih.gov/42075005/ https://www.nutraingredients.com/Article/2026/04/21/single-dose-creatine-may-support-cognition-in-sleep-deprivation-study/ https://pmc.ncbi.nlm.nih.gov/articles/PMC10902318/ https://medicalxpress.com/news/

If you're over 50 and still doing cardio to stay healthy, you're wasting your time and may actually be making things worse.

The person you love is either raising your hormones or destroying them, and most people have no idea which one is happening to them. John Gray, the author of one of the most beloved relationship books of all time, returns to reveal how your relational environment directly shapes your biology, and what you can do right now to hack it. Watch this episode on YouTube for the full video experience: https://www.youtube.com/@DaveAspreyBPR John Gray wrote Men Are from Mars, Women Are from Venus, the number one bestselling book of the entire decade and one of USA Today's top 10 most influential books of the last quarter century. His books have been translated into 45 languages across more than 100 countries. But what most people miss is that Gray is also a pioneer in the intersection of hormonal health, brain optimization, and human performance, a biohacker before the word existed. His newest book, Men Are from Mars for Women Only: Be Happy With or Without a Man, is the first in a six-part ser

If you are constantly bloated, fatigued, and feeling heavy, your gut bacteria have taken over. The standard advice is to just stop eating and do a multi-day water fast. But if your gut is already inflamed, a strict zero-calorie fast will actually spike your cortisol, trigger adrenaline crashes, and blow open the tight junctions in your intestinal wall.In this video, I break down the Italian fasting hack engineered by longevity researcher Valter Longo: The Fasting Mimicking Diet (FMD).I explain exactly how to structure this 5-day protocol to trick your body into autophagy (cellular cleanup) while still eating 800 to 1100 calories of specific fats and complex carbs. You will learn how constant "grazing" paralyzes your Migrating Motor Complex, why hidden proteins in vegetables are secretly kicking you out of fasting mode, and the exact step-by-step protocol to re-feed your microbiome on Day 6 without causing a massive inflammatory storm.Thank you to our sponsors!-GOT MOLD? | Go to http://gotmold.com/shopand

*Testosterone Directly Suppresses Brain Tumor Growth in Males by 38% Cleveland Clinic research funded by NIH shows testosterone binds androgen receptors in glioblastoma stem cells — the root of tumor recurrence — and cuts growth by 38% when levels are restored. Dave breaks down why the mainstream framing of testosterone and cancer risk has it backwards, what androgen deprivation therapy may be doing to every other cancer pathway simultaneously, and why your hormone panel is now a cancer conversation, not just a performance one. Sources:  -https://www.nih.gov/news-events/news-releases/nih-funded-study-suggests-testosterone-suppresses-brain-tumor-growth-males  -https://bioengineer.org/nih-funded-research-indicates-testosterone-may-inhibit-brain-tumor-growth-in-males/  *CDC Halts Rabies Testing Nationwide  A CDC staffing crisis has pushed rabies, mpox, and Epstein-Barr testing to overwhelmed state labs, creating one-to-two week diagnostic delays in a disease

I spent fifteen years living with brain fog until I realized the problem wasn’t in my brain, but in a nervous system stuck in a survival mode that pulls energy away from focus and memory. In this video, I explain why "trying harder" or popping supplements rarely works, and instead, I show you the 9,000-year-old ritual of heat and cold that pulls your body out of stress mode so clarity can actually return. I break down the specific science of how I use infrared wavelengths and contrast therapy to retrain the brain to stay calm under pressure, moving beyond temporary fixes to target the root cause of mental fatigue. Follow this protocol to finally complete your body's stress cycles, reset your biological default settings, and reclaim the lasting mental performance you’ve been missing.00:00 – Introduction01:02 – What Brain Fog Really Is03:00 – Why Trying Harder Doesn't Work04:51 – Supplements: Useful But Not Enough06:14 – Why Sauna Works07:32 – Infrared vs Traditional Sauna08:02 – Sunlighten Sauna Overview09:28

When you hit your 40s, you start catching colds more easily, wounds take longer to heal, and you feel rundown even after a full night's sleep. Your doctor will tell you "it's just aging." They're wrong.It's actually your immune cells suffocating on toxic waste because their power plants—your mitochondria—are breaking down.In this video, I explain the exact biological mechanism behind "immune aging" and why your body's natural cleanup system (mitophagy) stalls out in your 40s and 50s. More importantly, I'm sharing the breakthrough compound scientists discovered that actually reverses this. It's a molecule called Urolithin A, originally found in pomegranates.I dive into the massive problem with trying to get this molecule from food (only 30% of people have the right gut bacteria to even make it), and the 15 years of human clinical trials behind Mitopure—the supplement that bypasses your gut completely. I even share why I spent $100,000 on an extreme T-cell procedure before I knew I could just take this to get a
