Firefighters tout glutathione relief, but science calls for caution

Firefighters exposed to major California fires report rapid symptom relief after glutathione treatments, fueling interest in antioxidant therapies. But the IAFF warns there’s no robust evidence of effectiveness and points to safety concerns after product recalls, while IHAN- affiliated clinicians rely on anecdotal data rather than controlled trials. No large-scale clinical studies exist yet, underscoring the need for research and keeping proven protections like PPE and decontamination as the main safeguards.
