Rated 5 out of 5 by from Superior to the non-non-Pharmaceutical Grade My experience is this product has a more noticeable effect than the less expensive, non-Pharmaceutical Grade version. I don't like paying 3x as much as the non-Pharmaceutical Grade version, but at least I feel I'm getting what I pay for.

Rated 5 out of 5 by from Impressive! Hydrogen sulfide (rotten egg smell) is unfortunately very common among NAC products. The smell usually indicates degradation (plus possible impurities) in the NAC. This product, by contrast, was practically odorless when I opened it. Keep up the good work!

Rated 5 out of 5 by from Does what MD said it would. This supplement was recommended by my physician. He also recommended that I get them from Swanson's for their value, quality, and service. I am completely satisfied with the product. The only word of advise to others is that the capsule is quite large and very light. A sip of water before taking and a generous amount of water after swallowing works best for me.

Rated 5 out of 5 by from Some of the best in Amino's I've only been taking this amino acid for a couple of Months, but do notice an improvement. There are only two types of amino acids I will take, one is a liquid (like Bragg's), the other is AjiPure.
