    Hybrid Event

    Menopause Care in the Longevity Era Longevity medicine is everywhere right now. Supplements, protocols, influencer clinics, patients walking in with questions about interventions their doctors have never heard of. What's missing from most of it is the evidence. The Midlife Women's Health Summit is three days on what the research actually says about menopause care when you add a longevity lens. What works, what doesn't, what's being oversold, and what to tell the patient sitting in front of you. Co-chaired by Lisa Larkin, MD, FACP, MSCP, IF, Jen Gunter, MD, FRCS(C), FACOG, DABPM, ABPMR, and Lauren Streicher, MD, FACOG, MSCP; three of the clearest voices in women's health on separating data from marketing.
