Following their work on the destructive Eaton Fire in Los Angeles, members of the Pasadena Fire Department experienced symptoms such as difficulty sleeping, chronic cough, headaches, and fatigue. Fire Captain David Marquez reported that inhaling glutathione provided immediate relief for himself and his team after what he described as the worst exposure of his career.
Glutathione, an antioxidant naturally produced by the human body, has been administered to firefighters at major wildfire sites across the U.S. in recent years. Clinicians and fire departments have noted anecdotal evidence suggesting it may help remove cancer-causing chemicals absorbed during fires. However, comprehensive large-scale research on its safety and effectiveness is still pending.
The International Association of Fire Fighters (IAFF), representing over 360,000 firefighters in the U.S. and Canada, issued a rare warning regarding glutathione. The union cited recent recalls of contaminated glutathione supplies from compounding pharmacies. They also pointed to past scientific trials of other natural vitamins that, contrary to expectations, increased cancer risk.
Sean DeCrane, assistant to the general president for health and safety at the IAFF, stated that the organization does not know if glutathione is effective, if its perceived benefits are due to a placebo effect, or what its long-term effects might be. The IAFF opposes the way glutathione has been marketed to firefighters, including instances where morning briefings encouraged crews to visit volunteer treatment tents.
DeCrane added that the lack of research has raised significant concerns for the IAFF. The union has received reports from members who felt unwell or worse after receiving the treatment, with clinicians attributing their symptoms to "metals leaving your body."
Firefighters face an elevated risk of cancer, with a 14% increased risk of cancer mortality compared to the general American population, according to the U.S. National Institute for Occupational Safety and Health. This heightened susceptibility has fueled interest in alternative treatments, even those that may be unproven and potentially risky.
