N-Acetylcysteine (NAC)

Overview

In plain language

NAC is a precursor to glutathione, the body's master antioxidant. It supports respiratory health, liver detoxification, and provides powerful antioxidant protection while helping thin mucus in the airways.

NAC replenishes glutathione, one of the body’s most important antioxidants. It helps clear mucus from the airways, supports immune resilience, and may protect against oxidative brain stress. Commonly used for chronic lung conditions and cognitive support, NAC promotes clear breathing and energy metabolism. For seniors, it offers gentle respiratory and neurological protection.
