Special Announcement: Will YOU Be The Next BenGreenfieldFitness Podcast Host?

Full show notes: bengreenfieldlife.com/pharma

In this special repeat episode, Dr. Sandra Kaufmann breaks down which pharmaceuticals mimic the effects of things you already do for your health: what replaces a sauna session, what replaces a fast, what replaces a cold plunge (use code BENFORGE for $500 off select products), and what she takes with meals to blunt the damage from glucose spikes. I'm re-airing it now because of a new Nature paper finding that lithium is a naturally occurring brain nutrient, and that losing it may be one of the earliest steps toward Alzheimer's, at a dose in exactly the range Dr. Kaufmann described on this show years earlier.

You'll hear why she prefers pioglitazone over metformin for autophagy, how a Japanese gastritis drug connects to Alzheimer's, and how she worked her way up on an emergency blood pressure medication, starting at a dose that nearly knocked her off her feet and climbing to 100mg with no effect at all. The centerpiece is lithium (code BGL10 for 10% off): why the doses hidden inside popular nootropics are a fraction of what she considers useful, and everything it appears to do beyond mood, from controlling a pore in your mitochondria to building bone and growing new neurons. You'll also get her honest take on gene therapy versus pharmaceuticals, why peptides underperform in an older cell, and which molecule finally knocked astaxanthin off the top of her ranking system.

How to Replace Sauna, Fasting, and Cold Plunge With a Pill (WARNING: Proceed at Your Own Risk!) With Dr. Sandra Kaufmann

Full show notes: bengreenfieldlife.com/505

In this solosode, you'll get the latest on microplastics, spinal disc health, and what a heart scan sees that a cholesterol panel misses. A new seven-day trial pitted five plastic-avoidance strategies against each other, and the results tell you exactly where to spend your effort if you can't overhaul everything at once. You'll hear which plastic sources matter most and what I now take before bed with BrocElite® (use code BEN for 25% off your first month) to help clear microplastics from tissue. Then I get personal about my back. I'll walk you through my full-body MRI results, which show significant degeneration from L1 to S1, and explain why I still have almost zero back pain, from Dr. Stuart McGill's Big 3 to inversion hanging, the couch stretch, the founder stretch from Foundation Training, and my WALKOLUTION® treadmill desk ($100 off, enter your email for a unique code). You'll also learn why running was the only activity linked to healthier spinal discs in a study of more than 4,000 people, and why none of the sports people assume are hard on your back showed harm. Finally, you'll hear what a coronary CT angiography measures that your cholesterol panel cannot, why a 6,061-person study found plaque volume beats any standard risk calculator, what my own scan revealed, and the surprisingly simple thing that appears highly protective even when your plaque is already elevated.

The BIGGEST Step You Can Take To Reduce Microplastics, How To Get Rid of Back Pain, What You Need To Know About Heart Scans & More - Solosode #505

Full show notes: https://bengreenfieldlife.com/holyhealth

In this episode with Justin Roethlingshoefer, you'll hear from a former NHL performance coach turned health entrepreneur whose new book,Holy Health, is the one I chose for my father-son book club this month. This is not another eat-honey-and-drink-milk Bible health book. Justin is a genuine biohacker who works with pro athletes worldwide, and he has woven deep spiritual and physiological science into the same framework.

You'll learn why the modern obsession with optimization can quietly become idolatry, how the drive to control your metrics keeps your nervous system stuck in fight-or-flight and lowers your HRV, and the five "hearts" that trap high performers in striving. You'll also get the practical side: his full morning and evening rhythms, why he starts his day at 6 p.m. rather than at sunrise, the breathwork he does midday in the grass, his exact zone two and zone five weekly targets, and how he folds three and a half hours of zone two into family walks with a weighted vest. It's a conversation about doing less frantic optimizing and more intentional stewardship, and it may reframe how you think about every biohack you own.
