N-Acetyl-l-Cysteine (NAC) is a derivative of the dietary amino acid l-cysteine. NAC has a high affinity for lung tissue, which it supports through mucolytic and antioxidant action. By disrupting disulfide bonds, NAC thins mucus. It is a powerful free radical scavenger and thus supports the body's natural defense system. NAC supports tissue levels of glutathione, a key component of the antioxidant defense system. It also has the ability to help chelate heavy metals.
- Due to its sulfur content, NAC is able to disrupt disulfide bonds, thinning the mucus so that it, along with the trapped particles and bacteria, are more easily expelled from the lungs.
- NAC is a powerful free radical scavenger and thus supports epithelial cell health and healthy cilia activity in the respiratory tract.
- Tissues enhanced with glutathione support overall antioxidant protection and help to maintain a healthy immune response.
