Dr Christabelle Yeoh, integrative medicine physician, joins Lisa Costa-Bir for a deep dive into mitochondria — the organelles influencing nearly every tissue and process in the body. Moving beyond the outdated “powerhouse of the cell” view, Dr Yeoh explains how mitochondria act as processors of energy and evolutionary sentinels of immunity, redox balance, and cellular plasticity.

This episode explores how dysfunction manifests clinically — from fatigue and brain fog to autonomic dysregulation, poor vitamin D supplementation uptake, and maternal-line inheritance patterns. Dr Yeoh also shares practical “biophysics prescriptions”: exposure to sunrise and sunset, blocking blue light, eating only in daylight hours, grounding in nature, and regular movement to support mitochondrial quality control.

Warm, engaging, and invested in her subject, Dr Yeoh empowers practitioners with insights that place mitochondrial health as the foundation for patient care — and shows why aligning with natural rhythms is essential for resilience and recovery.
