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.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

NAC is rated 4.8 out of 5 by 13.
Rated 4 out of 5 by from NAC by NOW This is a combination product that I think serves me well. It is high on quality, value and convenience. I wish it had a little more selenium but over all the product works well. It has a flow agent but there is not a company to my knowledge that sells this without the flow agent. Without the flow agent the capsule could be smaller or a greater amount of selenium could fit into the capsule.

Rated 5 out of 5 by from Effective and Economical Product Swanson cautions me the government will not allow them to print any review with medical or disease claims ! I should be able to tell you my Neurologist told me to take N-Acetyl Cysteine like this one twice a day with my prescription meds. Doctor and I are happy with the results and I am happy with Swanson after 12 months and continuing ...

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
