I have pulmonary fibrosis, my doctor told me to use NAC, he also said that I could get it at a reasonable price from this site. He was right, not only does this product help my breathing, it doesn't cost a lot. Thank you so much for keeping your prices down & carring products that are worth while.

If you follow the directions and take these NAC pills away from food (along with SAMe) and the appropriate synergistic vitamins with food, it really really works.

I am an ex-smoker and lung cancer survivor - added to that I used to drink a lot years and years ago - That being said, my lungs have taken a beating and I have been diagnosed with emphysema. My liver function test reflect normal function, however, I have no doubt some damage resides there as well. Throw on top of that bad sinuses - summer time is awful for me between sinusitis, pollen and 1/3 of a lung missing - My breathing function gets very very difficult around summer time when it gets hot - high humidity is also a problem - Since I have been taking this product I have noticed a huge difference - my breathing is so much better - if that promise is true, I'll bet my liver is getting good benefit from this stuff - I highly recommend it! And as always, a shout out to iHerb for excellent prices, service and delivery - I recommend them to everyone as well - I'm a very happy customer.

This is a seriously powerful product. NAC is used for bronchitis, sinusitis, otitis media (middle ear infection), pneumonia and lung problems, and to protect the liver against Tylenol/acetaminophen poisoning and alcohol. The time release aspect of this product is important. Only use an NAC product which is time released because otherwise it metabolizes through the liver and out of the body in 1.5 hours. This product is well tolerated, does not cause headache or stomach upset. For acute problems, viruses, colds, flu or congestion, use 3 or 4 tablets, every 4 hours. You can feel congestion clearing in under 1 hour. This should also be used by people with HIV and cancer. I have seen this product work well many times. I always keep a spare bottle in my arsenal. If Bird Flu comes, I'm ready.
