The Human Upgrade: Biohacking for Longevity & Performance

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.

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 impair smell without people realizing it. 

The conversation dives into olfactory enrichment, including research showing major improvements in memory when older adults were exposed to multiple scents during sleep. Dr. Leon explains why novelty matters, how nighttime scent exposure may increase deep sleep and reduce nightmares, and why olfactory stimulation is being studied in dementia, PTSD, depression, and autism. Dave also explores connections between smell, GLP-1 drugs, exercise, rapamycin, spermidine, oxytocin, hormones, mitochondrial function, and other longevity interventions. 

This is essential listening for anyone interested in memory, sleep, Alzheimer’s prevention, brain aging, smell training, dementia, PTSD, autism, longevity, neuroplasticity, biohacking, and protecting cognitive function as you age. 

You’ll Learn: 

-Why your sense of smell often declines alongside memory 

-How smell connects directly to the brain’s memory and emotional centers 

-Why poor olfactory function is associated with Alzheimer’s risk and mortality 

-How chronic congestion may affect memory and brain health 

-What COVID-related smell loss may mean for long-term cognitive health 

-How olfactory enrichment can stimulate memory centers while you sleep 

-Why one study reported a 226% improvement in memory in healthy older adults 

-How scent exposure may increase deep sleep and reduce nightmares 

-Why novelty and rotating scents appear to matter for neuroplasticity 

-How smell training is being studied in dementia, depression, PTSD, and autism 

-Why several longevity interventions are also associated with improved olfaction 

-How GLP-1 drugs may affect smell, food enjoyment, memory, and emotion 

-Why professional wine tasters may offer clues about protecting the aging brain

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. Carolina explains the skin's "brick and mortar" barrier system, how declining estrogen affects collagen, ceramides, cholesterol, hyaluronic acid, and elastin, and why simply sealing moisture into your skin with occlusive products does not solve the underlying biology. They also explore why GLP-1 users can experience loose or sagging skin after rapid weight loss and what may help preserve skin structure over time. 

Carolina reveals how her team screened hundreds of peptides to develop OS-01, a senomorphic peptide designed to reduce the damaging signals produced by senescent "zombie" cells while supporting healthier skin function. In their research, OS-01 reduced markers of cellular senescence and inflammation, increased collagen production, and was associated with a 2.5-year reduction in measured biological skin age. She also explains why more peptides are not necessarily better, why some GHK-Cu formulations may fail to perform, and why peptide stability, concentration, delivery, and formulation matter. 

The conversation also covers why the skin around your eyes may biologically age decades faster than your cheeks, whether topical collagen really works, why cholesterol is essential for a healthy skin barrier, how over-moisturizing and "slugging" can backfire, and how damaged skin may contribute to systemic inflammation. Carolina also shares clinical data on OneSkin's new OS-01 Rich moisturizer, including improvements in hydration, firmness, fine lines, wrinkles, collagen, hyaluronic acid, and elastin. 

This is essential listening for anyone serious about skin longevity, anti-aging, menopause, GLP-1 weight loss, collagen, senescent cells, peptides, biological age testing, inflammation, hydration, hair and skin health, and maintaining younger-looking skin as you age. 

You'll Learn: 

-Why menopause can rapidly accelerate dry, thin, and crepey skin 

-How your skin's natural barrier holds water and why it breaks down with age 

-Why GLP-1 weight loss can make loose and sagging skin more noticeable 

-How senescent "zombie" cells accelerate inflammation and collagen loss 

-How OS-01 was associated with a 2.5-year reduction in biological skin age 

-Why skin around your eyes may be biologically much older than skin on your cheeks 

-Why topical collagen is different from collagen amino acids and collagen-producing signals 

-How cholesterol, ceramides, fatty acids, and hyaluronic acid support skin hydration 

-Why some GHK-Cu peptide products may not perform as expected 

-How over-moisturizing, face masks, Vaseline, and "slugging" can disrupt the skin barrier 

-How scientists measure the biological age of skin with epigenetic clocks 

-Why healthier skin may help lower inflammation throughout the body

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.

Apple Watch Series 12 Adds More HRV Data, Readiness Scoring, And Health Age 

Apple Watch Series 12 pushes deeper into health tracking with heart rate measurements every five seconds, substantially more frequent HRV sampling, a new daily Readiness score, and a Longevity section in the Health app featuring Health Age. Apple is also expanding its health ecosystem with daytime vitals, movement assessments, menopause tracking, and Quest Diagnostics lab ordering for more than fifty biomarkers. Host Dave Asprey explains why higher-frequency wearable data can become useful for spotting changes in stress, recovery, sleep, and illness, but warns against letting algorithmic scores override your own baseline, symptoms, and real-world performance.

FDA Moves To Accelerate Botanical Drug Development 

The FDA has opened a formal request for input on how to accelerate botanical drug development, including better clinical trial designs, stronger quality standards, improved standardization of complex plant mixtures, and expanded use of real-world evidence. The agency is also working with the European Medicines Agency on regulatory considerations for herbal and botanical medicines, potentially creating a clearer path for standardized plant-derived therapies to move beyond vague supplement claims and into more rigorous clinical testing. Host Dave Asprey breaks down why this could strengthen the evidence behind compounds like berberine, saffron, medicinal mushrooms, and flavanols, while also warning that more pharmaceutical-style regulation could increase costs and reduce access.

Persistent Adolescent Cannabis Use Linked To Long-Term IQ And Cognitive Decline 

A long-running New Zealand birth cohort found that people with persistent cannabis dependence beginning in adolescence showed significant cognitive decline by age thirty-eight, including losses in IQ, memory, processing speed, attention, and executive function. The most persistent users showed an average decline of roughly eight IQ points, while adult-onset users did not show the same pattern, pointing toward adolescence as a potentially important developmental vulnerability window. Host Dave Asprey explains why this 2012 observational study cannot prove cannabis caused every cognitive change, but argues that dose, frequency, age of exposure, and brain development all matter when evaluating cannabis for performance, health, or therapeutic use.

Pterostilbene Helps Mouse Muscle Cells Burn More Fat Through PPAR-Delta 

Researchers testing pterostilbene, a polyphenol found in blueberries and grapes, found that it reduced intracellular fat accumulation and increased fatty acid oxidation in cultured mouse muscle cells. Rather than directly activating PPAR-delta, pterostilbene appeared to slow its breakdown, leaving more of the protein available to regulate genes involved in fat metabolism and potentially offering a new mechanistic target for myosteatosis and metabolic dysfunction. Host Dave Asprey explains why the PPAR-delta mechanism is interesting for metabolic health, but draws a clear line between promising cell research and human outcomes, emphasizing that resistance training, walking, muscle mass, and mitochondrial health still have far stronger evidence than taking blueberry extracts to reduce muscle fat.

Dr. Karan Rajan on Fiber Fermentation, Sodium Myths, and What Your Poop Reveals About Disease Risk 

Your poop is more predictive than almost any other health signal, and you are flushing that data away every single day without a second look. 

Watch this episode on YouTube for the full video experience: 

https://www.youtube.com/@DaveAspreyBPR 

Host Dave Asprey sits down with Dr. Karan Rajan, a practicing NHS gastrointestinal surgeon, best-selling author, and Chief Science Officer at Throne, who has built a following of over 12 million people by making gut science accessible and actionable. He has spent his career removing colon cancers, treating digestive disease, and now studies how gut bacteria drive nearly every system in the body, from hormone metabolism to brain optimization. 

They break down why fibermaxxing can backfire without the right mix of fast, medium, and slow fermenting fibers, and why generic "eat more fiber" advice ignores what your gut bacteria actually need. The conversation covers protein absorption limits and how much your body can really use, the truth about saturated fat and metabolism, and why the sodium-to-potassium ratio matters more than sodium alone. They also dig into fasting and the gut's natural cleaning cycle, the estrobolome and testobolome and their role in hormone balance and longevity, and how AI is starting to reshape personalized health data, supplements, and functional medicine. Dr. Rajan shares some of the strangest objects he has surgically removed from patients, and explains what your poop's color, shape, and consistency reveal about liver function, inflammation, and disease risk long before symptoms show up anywhere else. 

This is essential listening for anyone serious about biohacking, gut health, human performance, longevity, mitochondria function, nootropics, ketosis, carnivore and fiber-based diets, sleep optimization, anti-aging, and hacking your metabolism from the inside out. 

You'll Learn: 

• Why fibermaxxing can cause bloating instead of better gut health 
• The real difference between fast, medium, and slow fermenting fibers 
• How much protein your gut can actually absorb and digest 
• Why low sodium may be more dangerous than high sodium for most people 
• How fasting triggers your gut's natural cleaning cycle, the migrating motor complex 
• What your poop's color and consistency can reveal about liver and metabolic health 
• How gut bacteria influence hormone metabolism through the estrobolome and testobolome 
• Where AI and functional medicine are headed in personalized gut health tracking

Most people fail to lose weight because they have a metabolic block nobody told them about. In this video, I’ve shared the three golden rules for losing 50 pounds fast, and why everything you've been told about weight loss is working directly against you.

You'll also learn:

• Why insulin resistance creates a metabolic block that locks your fat cells shut, no matter how hard you diet
• The overlooked reason constant snacking keeps insulin elevated all day, and why that alone can stall your fat loss
• Why most of your hunger isn't real hunger at all, and how conditioned cravings trick your body into eating when it doesn't need to
• The simple environmental shift that beats willpower every time, and why redesigning your kitchen matters more than any diet rule

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.

HEPA Air Filtration Linked To Measurable Brain Function Improvements In One Month 

A new study found that older adults using true HEPA filtration to reduce indoor fine particulate matter saw small but measurable cognitive improvements after just one month, adding to a growing body of evidence connecting air pollution exposure to neuroinflammation and long-term cognitive decline. Host Dave Asprey breaks down why clean air belongs in the biohacking conversation alongside supplements and training protocols, and why the World Health Organization's decision to list air pollution as a modifiable dementia risk factor is a bigger deal than it sounds.

Egg Yolk-Derived Peptides Show Neuroprotective Effects Against Oxidative Stress 

New research on phosphopeptides isolated from egg yolk phosvitin found that the compounds reduced reactive oxygen species, improved antioxidant defense markers, and increased neuron survival in cells exposed to oxidative stress in the lab. Host Dave Asprey connects this early but promising finding to his long-standing case for the whole egg, yolk included, as one of the most nutrient-dense foods available, and flags what would need to happen next for this to translate into a usable protocol.

Heat Stroke Survivors Face Elevated Cardiovascular Risk Years Later, Research Shows 

A closer look at heat stroke recovery reveals it's rarely a one-day event. Survivors of classic heat stroke had three and a half times the rate of ischemic heart disease twelve years later compared to matched controls, along with elevated long-term risk of kidney disease and lingering heat intolerance, fatigue, and dizziness. Host Dave Asprey draws the line between the controlled heat stress he uses deliberately in sauna and hyperthermic conditioning and the uncontrolled, uncooled heat exposure that leaves this kind of lasting cardiovascular damage, and what that distinction means for how to think about any stressor.

Long-Term Melatonin Use Linked To Nearly Double Heart Failure Risk In Large Cohort Study 

A cohort study of over 130,000 adults with chronic insomnia found that those who used melatonin for a year or more had nearly double the rate of heart failure and all-cause mortality compared to non-users, along with a three and a half times higher rate of heart failure hospitalization. Host Dave Asprey walks through why this is observational data, not proof of causation, and why he's stayed a low-dose, occasional melatonin user for years rather than a nightly one, plus what the real underlying driver of chronic insomnia might be for listeners still relying on it every night.

Jenny McCarthy on Reversing Autism, Healing Mold Toxicity, and the Biohacking Protocol Big Pharma Doesn't Want You to Know 

Back with another long one! Autism, mold poisoning, and cognitive decline share more root causes than most doctors admit, and this episode hands you the biohacking playbook to reverse all three.

Host Dave Asprey sits down with Jenny McCarthy Wahlberg, a New York Times bestselling author, actress, comedian, and 14-season judge on The Masked Singer who became one of the most trusted voices in the autism community after her son's regression following a vaccine reaction. She documented his recovery in books including Louder Than Words and Healing and Preventing Autism, founded the vegan, cruelty-free beauty brand Formless Beauty, and now develops unscripted television, documentaries, and podcasts with her husband Donnie Wahlberg through their Work Baby Productions banner under a first look deal with Lionsgate. 

Dave and Jenny trace her son's autism diagnosis back to a vaccine reaction and walk through the biohacking protocol that helped him recover, including candida detox, activated charcoal binders, collagen and hypermobility support, and hacking his gut with a low toxin diet that removed wheat and dairy. They connect autism to mitochondria energy collapse and neuroinflammation, and explain how nootropics like modafinil restore focus without the crash of stimulants. 

The conversation moves into longevity and human performance strategies for adults, covering low dose Cialis for brain blood flow, DHEA and thyroid optimization for women over 35, peptide protocols including melanotan and Retatrutide, cyclical ketosis and fasting alternatives, and why hormone replacement therapy reverses aging instead of causing cancer. 

They dig into functional medicine tools for everyday life: electrolytes and salt for blood pressure and sleep optimization, blackout darkness for circadian repair, baking soda for metabolism and alkaline balance, and why Jenny trusts krill oil over fish oil for anti-aging support. Dave breaks down ibogaine and neuroplasticity for brain repair, defends his carnivore leaning diet, shares why Danger Coffee still starts his morning, and calls out AI chatbots for pushing censored health narratives. 

This is essential listening for anyone interested in biohacking, human performance, longevity, functional medicine, brain optimization, and building a smarter, not harder approach to supplements and long-term health. 

You'll Learn: 

• How mold and candida trigger PANS and PANDAS, and why they mimic autism symptoms 
• Why activated charcoal timing determines whether it works as a binder 
• The link between collagen, hypermobility, and leaky gut in autism and long-term brain function 
• How modafinil, nicotine, and Cialis support brain optimization, focus, and mitochondria function 
• Why hormone replacement therapy and DHEA reverse aging in women after 35 
• The truth about ketosis supplements, structured water, and alkaline water myths 
• How darkness, light exposure, and electrolytes rebuild sleep optimization and metabolism
