Glutathione hype for wildfire smoke under scientific scrutiny
Amid wildfire smoke exposure, some firefighters tout glutathione as a protective remedy, but medical experts say there is no solid clinical evidence it is effective and warn that nebulized or specially prepared forms can be unsafe, with risks of airway irritation and contamination. Regulators have debated access to the supplement, and while glutathione is an antioxidant with plausible biology, more rigorous studies are needed before it can be recommended as a treatment or preventive for smoke exposure.
