Difficult to say if it works

Posted by chriswillisau on Oct 09, 2016

As with many supplements including this, I take them for the benefits of my body. Due to my illnesses, it's difficult to say if many products work. NAC is touted as being very good for the liver, and as we're all exposed to toxins in our diet and drinking water each day, as well as other afflictions that come along, I think it's a good idea to have more NAC in the diet for an extremely important organ. The price is cheap, too, and one per day with a hundred tablets - that's great value from a trusted brand.
