N-Acetyl Cysteine (NAC) is a stable form of the non-essential amino acid L-Cysteine. It is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures, and is also necessary for the formation of glutathione. Molybdenum and Selenium are essential trace minerals that facilitate the production of several important enzymes.

Customer Ratings & Reviews

Rated 4.9 out of 5 by 11 reviewers.
Rated 5 out of 5 by NAC is good Some of the lung products here include NAC. I was only able to get this version quickly where I live. It does include selenium & molybdenum (sp?) so may be better than straight NAC. Works well and NAC had no side effects either. December 28, 2013

Rated 5 out of 5 by NAC is a great value I have been using NOW NAC for 2 years now. I would never buy it from anyone but Swanson. They have the best quality and value that ive seen. March 7, 2013
Rated 5 out of 5 by Just another great product I have taken this product before and again recently but I am not finding any benefit from it. I don't know if it is something I just don't need now or if I am just not giving it enough time but I am not going to continue taking the product. There is nothing wrong with it, it is just my choice at this time. August 21, 2012
