In this wide-ranging conversation, Dr. Brian Lenzkes welcomes microbiome researcher and entrepreneur Martha Carlin to explore how our inner ecosystem shapes metabolic, neurological, and emotional health. Martha’s journey began when her husband was diagnosed with Parkinson’s disease. Trained as an auditor, she followed the evidence—into food systems, antibiotic exposure, and ultimately the trillions of organisms that live in and on us.
Martha shares how she discovered the connection between gut bacteria and Parkinson’s symptoms, developed probiotics that significantly improved her husband’s condition, and is now working on therapies for Crohn’s disease and post-antibiotic gut restoration. She also reveals the hidden dangers of glyphosate, explains why the “magic bullet” approach fails for complex diseases, and discusses the future of microbiome medicine.
In this episode, we discuss the surprising link between gut health and Parkinson’s, how glyphosate impacts your body on a cellular level, the microbiome’s role in chronic disease, and so much more.
Discover how gut health influences seasonal allergies through immune training, butyrate production, and microbial balance—plus practical ways to support your immune system from the inside out.
