About the Host

I’m Iris Josephina, a functional hormone specialist, orthomolecular hormone coach, circadian biology practitioner, and entrepreneur. Through Cycle Seeds and The Inner Rhythms Podcast, I support people in reconnecting with their cyclical nature, deepening body literacy, and reclaiming hormonal harmony from a place of sovereignty and embodied knowledge. Most people know me from Instagram, where I share stories, tools, and inspiration on cyclical living, menstrual cycles, fertility, hormones, and more.
