Episode Description from the Publisher

Sarah introduces an Evolving Wellness episode on estrogen clearance, perimenopause/menopause, and why estrogen therapy isn’t one-size-fits-all, then interviews John and David from Mera Labs, whose work on sulforaphane began after both of their wives faced breast cancer. They explain how sulforaphane activates NRF2, supporting phase 2/3 detoxification, antioxidant responses, mitochondrial function, and mitophagy, and discuss circadian oscillations of NRF2. Sarah shares her experience of heavy bleeding, PMS, and low ferritin improving after several cycles on their product, with benefits also noted for her autistic teen. The guests differentiate stabilized sulforaphane from glucoraphanin products, describe synergy from added PEITC, discuss dosing timing, toxins/microplastics and endocrine disruptors, DIM questions, stress and vagal regulation, and note a rare microbiome-driven estrogen recycling condition linked to galactorrhea— Connect with John and Davidhttps://mara-labs.com/ https://www.instagram.com/themaralabs/ For the next week, Evolving Wellness loyal listeners can get an exclusive 25% off all Mara Labs products when you go to www.mara-labs.com/SARAHK and use code SARAHK at checkout.
