N-Acetyl-L-Cysteine: Support for Respiratory Health and Detoxification

N-Acetyl-L-Cysteine (NAC) by SFI Health is a safe, effective amino acid derivative that provides powerful support for detoxification and respiratory function. As a precursor to glutathione, the body’s master antioxidant, NAC helps protect cells from oxidative damage. It also has a high affinity for lung tissue, where it acts as a mucolytic to promote healthy respiratory function and protect epithelial cells, making it a cornerstone supplement for cellular longevity.

How It Works: Glutathione Production and Mucus Disruption

NAC works through two primary pathways to support cellular and respiratory wellness.

A Precursor to Glutathione
NAC is a direct precursor to the critical antioxidant glutathione. Supplemental NAC raises glutathione levels in the body’s tissues, which is essential for protecting cells against free radical damage and maintaining a healthy immune response. Tissues enriched with glutathione provide robust antioxidant protection and support overall health.

Promoting Healthy Lung Function
The sulfur content in NAC allows it to disrupt disulfide bonds within mucus, effectively thinning it and making it easier to expel. This mucolytic action, combined with its ability to scavenge free radicals, helps support the health of the respiratory tract lining and promotes clear breathing.
