What if one nutrient could change everything about how you feel — from your energy and mood to how you show up as a mother?

In this deeply insightful episode, Dr Libby sits down with Dr Oscar Serrallach, functional medicine doctor and author of The Postnatal Depletion Cure, to explore how iron lies at the very heart of maternal health, postpartum recovery and even a baby’s early development.

Together, they unpack the biology behind the postnatal depletion epidemic — why so many mothers feel exhausted, foggy and emotionally stretched long after birth — and how modern “bounce-back” culture compounds the problem.

From the misunderstood science of iron deficiency to the emotional toll of self-doubt, guilt and relentless responsibility, Dr Oscar and Dr Libby reveal how restoring iron levels can transform not only energy and sleep, but emotional regulation and the mother–child bond itself.

Whether you’re preparing for pregnancy, navigating postpartum, or supporting a mother in your life, this episode is a powerful reminder that before we can rebuild wellbeing, we must first rebuild iron.
