The International Association of Fire Fighters issued a safety advisory last month after glutathione was offered to crews responding to blazes around Spokane Washington. The union representing more than 360000 firefighters across the United States and Canada cited two recent pharmacy recalls linked to bacterial contamination in the compounded antioxidant. Sean DeCrane the assistant to the general president for health and safety at the IAFF stated that the lack of published scientific studies proving its effectiveness in reducing toxins or oxidative stress raised serious concerns for the organisation.
A naturopathic group called the Integrated Health Action Network has provided nebulised and intravenous glutathione to firefighters at major wildfire incidents since 2017 when it first assisted crews during the Tubbs Fire in California. Co-founder Jen Riegle a licensed naturopath reported that participants experienced improvements in headaches fatigue and brain fog which rank among the most common symptoms reported by firefighters after prolonged smoke exposure. The group has collected feedback indicating clinically meaningful benefits although Riegle acknowledged the need for further testing to establish long-term safety.
Pilot studies organised by the network and partners showed substantial reductions in toxin levels among participating firefighters. In one 12-week programme involving 11 firefighters the total number of high-range toxins decreased by 81.4 percent while glyphosate levels fell by 93 percent according to data released by the Volunteer Fire Foundation. Participants also recorded drops in PFAS forever chemicals with researchers describing the outcomes as encouraging despite the small sample sizes.
Firefighters who received the treatments have spoken positively about their experiences. Pasadena Fire Captain David Marquez a 25-year veteran said I felt much better immediately after the worst exposure of my career. Marquez added that We were so desperate because of how messed up we were. We were willing to pretty much try anything after battling the Eaton Fire in Los Angeles.
Cancer remains the leading cause of line-of-duty deaths for firefighters accounting for approximately 70 percent of such fatalities in recent years the IAFF has reported. In the United Kingdom a study commissioned by the Fire Brigades Union and conducted by the University of Central Lancashire found that firefighters were 1.6 times more likely to die from cancer than the general population with even higher ratios for prostate and leukaemia cases. The research highlighted how occupational exposure to fire contaminants contributes to elevated risks across both countries.
Luke Montrose a professor at Colorado State University noted that glutathione possesses anti-inflammatory properties that could theoretically counter the effects of wildfire smoke. However he emphasised that its use as a supplement for detoxification has not been substantiated through large-scale clinical trials. Medical experts have also pointed to possible adverse reactions including in individuals with existing respiratory conditions.
The Food and Drug Administration does not approve glutathione for post-exposure firefighter detoxification and the IAFF has stressed that consumers should exercise caution regarding product safety and unverified health claims. Despite the union’s position some fire departments have continued to explore the treatment while advocating for more comprehensive research to determine its true value and risks.
