Review (5/5): Excellent Investment
I have been taking NAC for 27 years since I am a smoker. It helps to get the flem out of the lungs. I normally take one a day, however, if I feel congested I take 2-3 capsules a day. This is also good for bronchitis or any other chronic lung congestion. Highly recommend. NOW brand is a very good quality brand and also recommend it as well.
