N-Acetyl-l-Cysteine (NAC) is a cellular antioxidant support that specifically promotes healthy lung tissue and supports glutathione levels in tissues.

NAC has a high affinity for lung tissue, supporting it through mucolytic and antioxidant action. It disrupts disulfide bonds in mucus, thinning and easing its expulsion, while supporting epithelial cell health and healthy cilia activity in the respiratory tract.

NAC is a precursor to the antioxidant glutathione, increasing tissue levels and supporting overall antioxidant protection. It helps maintain a healthy immune response by supporting lymphocytes, which rely on glutathione to function properly.

Research indicates that NAC supplementation supports upper respiratory tract and immune system health. A meta-analysis of double-blind, placebo-controlled trials provided additional support for NAC's benefits for respiratory health.

Each vegetarian capsule contains 900 mg of NAC, making it a convenient and effective supplement for those seeking respiratory and immune system support.
