EP 1426
1426. I Take 150 Pills a Day (But This One Is My Workhorse) | Resbiotic
Dr. Vivek Lal, double board-certified physician, neonatologist, and CEO of Resbiotic Nutrition, joins Host Dave Asprey to break down the gut-lung axis he discovered while sequencing lung samples from premature infants at the University of Alabama at Birmingham, why lungs were long assumed to be sterile until his lab proved otherwise, how specific bacterial strains make lungs resilient or susceptible to inflammation regardless of genetics, the decade of research behind MMP-9, the collagen-breaking pathway he calls the next major target for longevity after sirtuins, how his three-strain probiotic formulation downregulates MMP-9, the NLRP3 inflammasome, and the NF-kappa B pathway without the side effects of steroids, why chronic antibiotic use and toxic mold exposure can disrupt lung bacteria for years and drive lifelong inflammation, how breathwork and lung training measurably change the composition of the lung microbiome, the science behind postbiotics and why dead bacteria can still trigger a beneficial immune response, the years-long process of particle engineering an inhalable probiotic capable of reaching deep lung tissue, and why he believes self-experimentation should be treated as a right rather than something requiring years of regulatory approval. Essential listening for anyone serious about biohacking, human performance, longevity, functional medicine, anti-aging, supplements, and smarter not harder approaches to respiratory and metabolic health.

The Gut-Lung Axis: The Missing Link in Chronic Inflammation & Aging | Dr. Vivek Lal
Your lungs have a microbiome, and almost no one is talking about it. This episode reveals the hidden pathway behind asthma, chronic inflammation, and slow aging, and gives you a science-backed way to biohack your breath from the inside out.

Host Dave Asprey sits down with Dr. Vivek Lal, MD, FAAP, a double board-certified physician scientist who discovered the gut-lung axis while running the Pulmonary Microbiome Lab at the University of Alabama at Birmingham. He serves as Director of Clinical Innovation at UAB’s Marnix Heersink Institute of Biomedical Innovation and trained in pulmonary and vascular biology at UT Southwestern before completing MIT’s executive program in drug and device development. As a serial entrepreneur through his venture studio Biostack Ventures, he founded and now serves as CEO of Resbiotic Nutrition, and also launched Alveolus Bio, an FDA-track pulmonary drug development company. His decade of research turned into the world’s first probiotic built specifically for respiratory health.
Dave and Vivek break down MMP-9, the overlooked inflammatory pathway that drives collagen breakdown, chronic lung disease, and accelerated aging throughout the body. They cover why germ-free mice outperform normal mice, how antibiotics and toxic mold reshape your lung bacteria for years, why breathwork actually changes your lung microbiome, and how postbiotics and inhaled probiotics could become the next frontier in functional medicine. Along the way they get into supplement formulation, drug development red tape, and why self-experimentation should be treated as a right, not a privilege.
You’ll Learn:
- What the gut-lung axis is and how gut bacteria control inflammation in your lungs
- Why MMP-9 may be the next major longevity pathway after sirtuins
- How antibiotics, toxic mold, and vaping damage your lung microbiome long term
- Why breathwork and lung training measurably change your lung bacteria
- How postbiotics and inhaled probiotics could replace inhalers and steroids
- Why product-level clinical testing matters more than single-ingredient hype
- How self-experimentation, AI, and personalized data are reshaping medicine

"Lung training, breathwork does change your lung microbiome and can lead to inflammatory pathways being down-regulated."
Vivek Lal
00:00 – Cold Open
Dr. Vivek Lal explains how breathwork and lung training change the lung microbiome and can make kids immune to strep and seasonal viruses.
01:08 – Intro
Dave introduces Dr. Vivek Lal, the neonatologist and physician scientist who discovered the gut-lung axis and invented the world’s first FDA-cleared probiotic for lung health.
05:17 – Discovering the Lung Microbiome
Dr. Lal walks through how his lab at UAB proved lungs are not sterile, sequencing samples from premature infants to identify which bacterial strains make lungs resilient or susceptible to inflammation.
16:58 – Antibiotics’ Effect on Lungs
Dave and Dr. Lal discuss how chronic antibiotic use disrupts the lung and gut microbiome for years, leaving people more prone to infection, inflammation, and chronic lung disease later in life.
20:30 – MMP-9 Explained
Dr. Lal breaks down MMP-9, the protease that drives collagen breakdown and neutrophilic inflammation, and explains how his Resbiotic formulation downregulates it at the source.
25:56 – NLRP3 & the Inflammasome
They dig into the NLRP3 inflammasome and NF-kappa B pathway, the inflammatory signaling routes that steroids target, and how specific probiotic strains can downregulate them without the side effects.
31:36 – The Right to Self-Experiment
Dave and Dr. Lal make the case for treating self-experimentation as a right, criticizing regulatory barriers that slow drug development and keep effective treatments out of reach.
42:04 – Lung Training
Dr. Lal confirms that breathwork practices like pranayama physically change lung compliance and the lung microbiome, and shares his plans to study the mechanism at a population level.
1:00:18 – Astronaut Microbiomes
Dave and Dr. Lal explore the unstudied role of gut and lung probiotics in preparing astronauts for long-term space travel to Mars.
1:12:33 – Closing & Discount Code
Dave recaps the case for MMP-9 as the next major longevity pathway and directs listeners to Resbiotic.com with code DAVE20 for a discount.
