In this episode, Cheryl Sew Hoy explains how gut health affects immunity, mental health, hormones, and resilience, drawing on both microbiome science and her own experience building Tiny Health. She shares how a deeply personal journey into motherhood led her to rethink gut health as a foundation for lifelong wellbeing, and why the microbiome - particularly in the first 1,000 days of a babies life - plays a critical role in immune health, resilience, and mental health.The conversation moves through what the gut actually does, why balance and diversity matter more than eliminating bacteria, and how the gut–brain connection works, including the surprising number of key hormones produced in the gut. Cheryl also explains why testing and education offer clearer direction than supplements or guesswork, and how factors like birth interventions, antibiotics, diet, sleep, and stress shape gut health over time.

Alongside this, she reflects on entrepreneurship, parenting, and sleep, and what it means to live a bountiful life that feels full, without taking life too seriously.
