One cup of blueberries a day can improve vascular function, support the aging brain, and tighten glucose control in ways that go far beyond antioxidant activity. In this episode, Dr. Rhonda Patrick breaks down how blueberry anthocyanins and their downstream metabolites act as signaling molecules that support endothelial function and memory, while long-term studies link regular blueberry intake to slower cognitive decline and lower dementia risk. She also details the evidence for post-meal glucose control and insulin sensitivity, and explains why blending blueberries with bananas may reduce polyphenol availability.

#113 Why AI Could Add Decades to Your Lifespan | Dr. Derya Unutmaz
The next 10 years may add decades to human lifespan by compressing the time it takes to understand, treat, and prevent disease. In this episode, Dr. Derya Unutmaz explains why accelerating AI could transform drug discovery, shorten clinical trials, and push cancer treatment toward increasingly personalized interventions. He also reframes AI not as an existential threat, but as a medical enabler that doctors may soon be ethically obligated to use.

#112 How To Slow Biological Aging With a Multivitamin, Vegetables, & Omega-3 | Dr. Steve Horvath
The strongest anti-aging strategy may be less about dramatic reversal and more about removing what accelerates aging in the first place. In this episode, Dr. Steve Horvath maps out the science behind biological age and how aging clocks are changing the way researchers evaluate longevity interventions. He also explains why omega-3s, a daily multivitamin, and sufficient vegetable intake stand out as evidence-backed, compounding levers for shifting biological age over time.

#111 The Optimal Mobility Protocol for a Durable Body | Dr. Kelly Starrett
Range of motion is the one aspect of your physiology that doesn't have to decline with age, but neglect almost guarantees that it will. In this episode, Dr. Kelly Starrett explains how to build a durable body by restoring the movement patterns that modern life strips away. He also lays out a clear framework for raising resilient young athletes grounded in sleep, fueling, play, and skill development rather than early specialization and excess volume.

#110 How To Build Lasting Happiness | Dr. Arthur Brooks
Most of us are pursuing happiness exactly the wrong way. Overuse of technology is creating a meaning deficit, rewiring our brains away from purpose. In this episode, Dr. Arthur Brooks explains why relentless device use prevents us from asking the critical questions that define our lives, why high achievers often feel profoundly empty, and how the "striver's curse" makes satisfaction fleeting. He also shares his five-step protocol for managing negative affect and explains why suffering, when approached correctly, is a potent catalyst for personal growth.

Many symptoms attributed to aging are also consistent with chronic inflammatory stress and impaired NAD metabolism. Dr. Charles Brenner explains the mechanisms, the human data, and what interventions actually move the needle. He also cuts through the crowded world of NAD boosters, including oral NAD pills, NMN, NR, and NAD IV drips, clarifying what actually raises NAD in humans and what emerging research suggests about NR for lowering inflammation and improving recovery.

One minute of vigorous exercise may be worth up to ten minutes of "moderate" cardio for extending lifespan and preventing chronic disease. In this Journal Club episode, Rhonda Patrick, PhD and endurance athlete Brady Holmer dissect a new Nature Communications study of more than 70,000 adults showing that vigorous intensity is roughly 4–10x more potent than moderate activity for reducing all-cause mortality, cardiovascular events, type 2 diabetes, and cancer outcomes—far beyond the long-standing 1:2 rule embedded in global exercise guidelines.

Chronic insomnia and untreated sleep apnea profoundly accelerate cognitive decline, impair performance, and diminish resilience. In this episode, Dr. Michael Grandner outlines practical, scientifically validated interventions, including CBT-I and stimulus control strategies, to retrain your body for consistently restorative sleep. He provides critical insights into detecting hidden sleep apnea and explains how precise timing of morning light, caffeine, and supplements like melatonin can dramatically enhance sleep quality and daytime performance. Dr. Grandner also shares actionable tips for falling asleep faster, managing nighttime awakenings, and provides an honest look at the accuracy and pitfalls of sleep trackers.

When testosterone runs low, libido isn't the only casualty—muscle mass drops, fat accumulates, insulin resistance rises, and motivation declines. In this episode, Derek from More Plates More Dates highlights common pitfalls that suppress testosterone and evaluates popular testosterone-boosting supplements like Tongkat Ali, boron, and ashwagandha, clarifying what's evidence-based versus overhyped. He also details practical strategies for testosterone replacement therapy (TRT), covering optimal delivery methods, benefits, risks, fertility implications, and key biomarkers to monitor.
