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
