Rated 1 out of 5 by from Very odd smell and aftertaste. Trying to work with Puritan's Pride to determine if it was simple an off batch.

Rated 5 out of 5 by from great smell is bad but i assume its from the sulfur, which should be the best form of mac

Rated 5 out of 5 by from glass container lessens bad smell. i bought another brand and when i opened it i did find this bad smell as well... reading up on it, it appears it is par for the course with this medication. However, if i put one whole bottle into a small glass jar - a half pint canning jar is perfect - the smell becomes more organic and natural and less toxic smelling. i think something in this medication interacts with the gelatin and the plastic containers.

Rated 5 out of 5 by from Energy in action! I got that energy fueling supplement immediately after every meal, but on condition to have it along with its synergistic Puritan's Pride ALA cps. Very good, effective product.

Rated 5 out of 5 by from good Good, except when I opened the bottle there was a horrible smell, so I'm wondering why. The last bottle of NAC I bought from NOW did not have a smell

Rated 5 out of 5 by from Excellent product, great price. Some people take glutathione supplements that aren't easily absorbed. NAC helps your body produce its own glutathione which is a great antioxidant. The Puritan price is unbeatable for this product.

Rated 5 out of 5 by from N-Acetylcysteine We just started taking this product and I can't really review it this quickly, but, it has all sorts of uses and it is an antioxidant and comes highly recommended to me.

Rated 5 out of 5 by from An essential part of my getting older and what nots. I have used Puritans Pride since 1998. This product meets all my expectations and more.

Rated 5 out of 5 by from .I highly recommend when taken with other supplements. NAC combined with B12 and folic acid are fantastic for keeping my mood healthy. VALUE IS EXCELLENT ALSO but I thought I was supposed to click on the word value and when I did it rated it fair. If Puritans can correct this, I would appreciate it. Might help to give instructions in future.

Rated 5 out of 5 by from N-Acetyl Cysteine Great product and I will order it again. This has been a difficult product to find and Puritan's Pride always has it in stock.

Rated 3 out of 5 by from can't really know If one is otherwise very healthy as I am at age 70, and taking lots of other supplements, there will never be a way to evaluate this product. I take it as part of my anti-aging strategy from the advice of an anti aging newsletter I get and do so just in case it helps. I am not too concerned that the last batch of these has a petroleum odor that the previous batch did not. I reported it and they sent me some more of a different code and it too has that odor. I continue nevertheless.
