About NAC (N-Acetyl-Cysteine)

NAC is a highly potent antioxidant that complements the body's own free-radical fighting ability.

NAC (N-Acetyl L-Cysteine) acts as a free-radical scavenger and inhibits the production of reactive oxygen species which can damage cellular structures. It also helps replenish intracellular glutathione, another vital cellular antioxidant produced by the body. Supplemental NAC is well absorbed, so it can be counted on to support against oxidative stress..

Evidence suggests that regular use of N-acetyl-cysteine (NAC) is helpful for individuals with chronic bronchitis, a condition commonly associated with smoking and emphysema. NAC is a natural expectorant which help thin mucus and loosen phlegm and bronchial secretions. NAC may also be helpful in a life-threatening condition called acute respiratory distress syndrome.

Scientific Studies

Chronic Bronchitis

Individuals who have smoked cigarettes for many years eventually develop deterioration in their lungs leading to various symptoms, including chronic production of thick mucus. This so-called chronic bronchitis tends to flare up periodically into severe acute attacks possibly requiring hospitalization. Regular use of NAC may diminish the number of these attacks. A review and meta-analysis selected eight double-blind placebo-controlled trials of NAC for chronic bronchitis. 1-9 The results of these studies, involving a total of about 1,400 individuals, suggest that NAC taken daily at a dose of 400 to 1,200 mg can reduce the number of acute attacks of severe bronchitis.
