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 increases tissue levels of glutathione, a key component of the antioxidant defense system. It also has the ability to chelate heavy metals.
NAC provides potent nutritional support to all body cells as an antioxidant and specifically supports proper lung functioning through its mucolytic capability.
