NAC is a slightly modified version of the sulfur-containing amino acid cysteine. When taken internally, NAC replenishes intracellular levels of the natural antioxidant glutathione (GSH), which is often deficient with advancing age and in chronic illness, thus helping to restore cellsâ ability to fight damage from free radicals. NAC is used to relief from the coughing, wheezing, and thick phlegm associated with cold and flu. In addition, studies have shown that NAC provides the following benefits:
Â· protection against avian influenza and more common seasonal flu symptoms.
Â· reduction in the frequency and duration of attacks of chronic obstructive pulmonary disease (COPD) and may slow the clinical course of idiopathic pulmonary fibrosis (IPF).
Â· improved insulin sensitivity in people with some of the most difficult-to-treat metabolic disorders.
Â· NAC blocks cancer development at virtually every step in the process, and through multiple mechanisms
Â· NAC fights the stomach infection Helicobacter pylori on two fronts, inhibiting the organismâs growth while reducing production of inflammatory cytokines that can lead to gastritis and cancer
