IAFF, FDA Issue Wildland Firefighter Glutathione Supplement Warning

• Fire and medical officials issued warnings about an unapproved glutathione supplement offered to wildland firefighters.
• The supplement, administered via IV or nebulizer, has not been proven safe or effective and is not FDA-approved.
• At least two pharmacies recalled the product in August due to bacterial contamination, with one reporting adverse symptoms like fever and severe headache.
• The International Association of Firefighters (IAFF) issued a safety advisory, noting concerns from physicians and members about unsubstantiated health claims.
• The Integrative Healers Action Network, a group of naturopaths, provided the supplement to firefighters during recent and past wildfires.

The IAFF emphasized that because glutathione is not an FDA-approved drug, consumers should exercise extreme caution regarding both the product's safety and any claims suggesting its ability to treat or prevent diseases.

Fire and medical authorities have recently issued a significant wildland firefighter glutathione supplement warning, cautioning against the use of a product offered to those battling blazes across the Western United States. The supplement, glutathione, administered either intravenously or via a nebulizer, has not undergone the necessary evaluations to confirm its safety or effectiveness. Experts highlight a critical risk: potential illness for users if the product becomes contaminated during its manufacturing process.

Concerns escalated following a glutathione recall bacterial contamination incident in August, when at least two pharmacies withdrew the supplement from circulation. Laboratory testing at these facilities confirmed the presence of bacterial contamination. One of the pharmacies reported receiving accounts of individuals experiencing adverse reactions, including fever, chills, severe headaches, and other symptoms, after using the product.

The International Association of Firefighters (IAFF), a labor union representing approximately 360,000 first responders, underscored these dangers in a safety advisory issued last week. The IAFF emphasized that because glutathione is not an FDA-approved drug, consumers should exercise extreme caution regarding both the product's safety and any claims suggesting its ability to treat or prevent diseases. This advisory highlights the significant regulatory gap for unapproved glutathione FDA firefighters might encounter.

The IAFF glutathione safety advisory emerged after the supplement was actively promoted to firefighters during recent wildfires that devastated areas in and around Spokane, Washington. During morning briefings at the fire scenes, medical unit leaders from California encouraged crews to visit a tent where a nonprofit organization, staffed by licensed naturopathic doctors, was distributing the product. This group, identified as The Integrative Healers Action Network glutathione providers, had previously supplied the supplement to firefighters during the January 2025 wildfires in Los Angeles County, with their involvement tracing back to a 2017 blaze in California's wine country.

Despite the absence of scientific evidence supporting its use, some firefighters have reported feeling better after inhaling toxic smoke and have advocated against restrictions on access to the supplement by California pharmacy officials. However, the promotion in Spokane prompted physicians and IAFF members to voice concerns to the union regarding unsubstantiated health claims and the lack of research into the supplement's safety. Sean DeCrane, the Director, Firefighter Health and Safety Operational Services for the International Association of Fire Fighters, confirmed that the union also received reports of firefighters feeling worse or becoming ill after receiving the treatment. DeCrane stressed the necessity for all medical treatments marketed to firefighters to undergo thorough evaluation and testing to prevent unforeseen negative consequences.

In response to the safety advisory, Jen Riegle, a naturopathic doctor and co-founder of The Integrative Healers Action Network, acknowledged the critical need for peer-reviewed research to determine if glutathione can effectively reduce chemical burdens in firefighters. She stated that the organization is actively exploring partnerships to facilitate such studies.

The context for this wildland firefighter glutathione supplement warning is the escalating health crisis posed by wildfire smoke exposure. A growing body of research increasingly demonstrates the extensive negative health impacts of inhaling wildfire smoke, which becomes particularly hazardous when fires spread through urban environments, incinerating household appliances, batteries, and various chemicals. Annually, tens of thousands of individuals in the United States succumb to the long-term health consequences of wildfire smoke exposure.

Firefighters, operating under extreme conditions, face unique challenges that render the use of respirators with oxygen tanks impractical. This reality means they are routinely exposed to a wide array of chemicals that can have both immediate and lasting detrimental effects on their health, as noted by Sean DeCrane. Pasadena Fire Captain Matt Caffey, a paramedic for 28 years who fought last year's Eaton fire in Southern California, shared his personal experience, describing how smoke exposure from burning neighborhoods led to symptoms such as coughing, vomiting, and severe brain fog. He recounted feeling unable to remember things, constantly "behind the eight ball," and struggling to recover. This pervasive and severe occupational health risk underscores the urgent need for effective, proven interventions, while simultaneously highlighting the dangers of unverified treatments.

This development highlights significant product liability and regulatory compliance risks for entities involved in manufacturing, distributing, or recommending unapproved supplements, particularly when bacterial contamination leads to adverse health effects. Legal counsel should advise clients on FDA regulations, recall procedures, and potential claims from individuals harmed by such products, especially within occupational health contexts.
