Most probiotics sound impressive… until you look at what they actually do in the body. In this episode of The TBD Fit Podcast, Dr. Kiran Krishnan joins us to explain why many probiotic formulas are poorly designed, why spore-based organisms are built to survive digestion, and how they support gut barrier integrity, microbial balance, and immune modulation.
Tune in as we explore how diversity protects long-term resilience and why skin issues like eczema can reflect a larger gut–immune–microbiome loop driven by dysbiosis and loss of tolerance.
