Lauren Lowenstein

Lauren Lowenstein is a leading voice in the world of chronic inflammatory illness, environmental health, and patient advocacy. A certified CIRS coach and consultant widely known as The Biotoxin Lady, her work is rooted in both lived experience and years of deep research. As a mother of two boys who were also impacted by CIRS, her passion for this work is profoundly personal. After enduring years of accumulating diagnoses, Lauren navigated her way to the root cause: CIRS, Chronic Inflammatory Response Syndrome.

That discovery changed the course of her life. Through her work as a coach, consultant, educator, and speaker, Lauren has become a trusted bridge between patients, practitioners, and the often-overlooked environmental factors that can profoundly impact healing. What sets Lauren apart is not only her ability to translate complex science into clear, actionable education, but her deep understanding that true healing often requires more than symptom management alone. Her knowledge of environmental biotoxins has enabled her to help clients address one of the most critical and frequently missed pieces of recovery: the building itself.

Lauren is especially passionate about raising awareness that these illnesses are not solely about mold, but can also involve endotoxins and other indoor biotoxins that significantly affect health. Her work continues to bring greater awareness to indoor air quality, environmental investigation, and the essential role a safe home plays in creating the conditions for healing.
