Dr. Libby Weaver on the Forgotten Supernutrient | SNH Podcast #159

In this episode of the Smarter Not Harder Podcast, Dr. Libby Weaver joins Jodi Duval for an illuminating conversation about iron — the most overlooked yet essential nutrient for mood, cognition, metabolism, and long-term health. Together, they break down myths, lab test pitfalls, supplement confusion, and why so many women and children remain iron-deficient despite "normal" results. From hepcidin and hormone shifts to sport, anxiety, and pregnancy, this is the deep dive into iron you didn't know you needed. Join us as we explore: • What hepcidin is and why it's the key to iron absorption   • Why teenage girls and high-performing women are so often iron-deficient   • Iron infusions: when they're needed — and when they're not   • Testing errors, supplement types, and food-based solutions This episode is for you if: • You've ever been told your iron is "normal" but still feel exhausted   • You've had recurring iron infusions or failed supplements   • You're a practitioner wanting clarity on dosing, testing, and absorption   • You want to support kids, teens, and athletes with better iron strategies You can also find this episode on…Youtube: https://youtu.be/chuWc53iw2g Find more from Dr. Libby Weaver:   Website: https://www.drlibby.com Instagram: https://www.instagram.com/DrLibby/ Facebook: https://www.facebook.com/DrLibbyLive YouTube: https://www.youtube.com/@drlibby6300 LinkedIn: https://www.linkedin.com/in/dr-libby-phd-3a497531/ Find more from Smarter Not Harder:   Website: https://troscriptions.com/blogs/podcast?utm_source=youtube&utm_medium=video&utm_campaign=snh_podcast_guest_episode_2025_10&utm_content=podcast_asset  Instagram: https://www.instagram.com/troscriptions HOMeHOPe Virtual Symposium 2026: https://homehope.org/homehope-virtual-symposium-2026 Get 10% Off your purchase of the Clinical Metabolomics module with code PODCAST10 at https://www.homehope.org Get 10% Off your Troscriptions purchase with code POD10 at https://www.troscriptions.com Get daily content from the hosts of Smarter Not Harder by following @troscriptions on Instagram.
