Supplements and medications for respiratory resilience against air pollution

Air pollution is a major threat to respiratory health. In this article, we review the current literature on accessible interventions that could help patients build resilience against this threat. We explore the potential benefits of antioxidant-rich diets, including supplements such as fish oil, vitamins C, D and E, and prebiotics, which have shown promise in reducing inflammation and oxidative stress, thereby mitigating air pollution-related respiratory decline. Nasal washes are commonly used to clear nasal passages, which could help to clear pollutants from the nasal passages and improve mucociliary clearance. Furthermore, medications such as nonsteroidal anti-inflammatory drugs and intranasal corticosteroids have been reported to reduce pollutant-related airway inflammation and lung function deterioration triggered by pollutant exposure. Given the generally favourable safety profile of these interventions, they are reasonable to consider in consultation with a care provider. Further research is needed to establish optimal dosing, safety and long-term efficacy, particularly for those exposed to chronic air pollution. Healthcare professionals should work together to further identify and implement effective interventions to mitigate the impact of air pollution on respiratory health.
