N-A-C Sustain 600 mg 100 Bilayer Tablets

Posted by iHerb Customer on October 11 2011 | Verified Purchase

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.

Jarrow NAC

Posted by CriticalReviewer on November 29 2009 | Verified Purchase

My doctor prescribed a theraputic dose of NAC to aid with a lung condition. It always gave me a headache, until I began using NAC by Jarrow. With their sustained release product, I no longer get the headaches.

Makes aging a little easier

Posted by iHerb Customer on August 27 2009 | Verified Purchase

As a precursor to glutathione, a major detoxifier in the lungs and liver, NAC helps in everyday living. But NAC itself helps to breakdown alcohol directly and makes hangovers all but disappear. I recommend taking two before drinking with a full glass of water and two before going to bed. The next morning will be too late!!! Have fun thirtysomethings!

Immune Booster, Decongestant, Liver Protection

Posted by iHerb Customer on January 23 2007 | Verified Purchase

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.

After purchasing this product and doing more research, I discovered that there really is no reason to take n-a-c in a sustained form, and that a sustained release is perfectly achievable by administration with food.

Liver Tonic and More

Posted by RubiesHealth on October 8 2012 | Verified Purchase

The body makes glutathione from NAC. The former is an antioxidant that supports the liver in immunity and detoxification functions. It also serves many other functions including promoting eye and mucus membrane health. The sinuses and lungs are lined with mucus membrane. I first used NAC for lung support in road-running sport because of traffic pollution. Within a few days of use, I noticed thinner and healthier mucus production and months after, improved resistance against prevailing flu and haze-induced coughs. It provides the same consistent benefit for all whom I recommend this product to. We take only 1 tablet on empty stomach daily.

Physician Recommended

My physican recommended both this product and the Jarrows Alpha Lipoic Sustain to me. The "sustain" better regulates my metabolism and keeps my blood sugar stabilized. I have been able to lose weight taking both these products together, and I no longer have those vexing late afternoon hunger pangs.

Thanks for your feedback!

Great stuff

Posted by iHerb Customer on February 23 2011 | Verified Purchase

We got this for a gentle detox because my daughter's health is too poor to do an aggressive detox. She is handling this just fine and she is gaining lots of energy. Just slightly hard on her tummy, but tolerable, even for her weak system.

Helped with Candida detox when nothing else did

Posted by iHerb Customer on July 26 2010 | Verified Purchase

After 4 months on Erica White's Candida program (a well-regarded diet and supplement program designed to starve to death Candida in the body) I was sick and toxic to the point where I could hardly work. In all my years of health probems this feeling of toxicity (and accompanying physical weakness) was something I hadn't experienced before. This supplement reduced the debilitating nature of the experience quite a bit. I still don't feel great, but am much better than I was and am able to persist with the Candida program. NOW Foods Silymarin complex - another recommended supplement for managing detox symptoms by strengthening the liver - didn't work for me.
