Fine particulate matter (PM2.5)

Vitamin C may offer meaningful protection against the invisible but pervasive threat of fine-particle air pollution. The common antioxidant significantly reduced lung inflammation and cellular damage caused by everyday, low-level exposure to PM2.5.

New research has identified the mechanism by which air pollution damages the lungs’ self-cleaning system, leaving us vulnerable to infection. In doing so, it has also identified a way to reverse that damage and restore lung function.
