How much NAC is safe per day

Posted by formergardener @formergardener, May 28, 2023

Hello. I read that NAC can protect the hair cells inside the air from damage done by some of the MAC meds. I also read about its protective effect on the liver and kidneys.

My question is how much is recommended for protection? I have been using 600 mg at night because it helps to thin mucus and is said to help battle mycobacterium avium.

Have any of you had personal experience with the effects from NAC?

Interested in more discussions like this? Go to the MAC & Bronchiectasis Support Group.

@sueinmn Hi Sue, Can you please tell me what brand of NAC you use? Just saw my ID doc at UMN and he was very supportive of my decision to use it for bronchial support. I'll need to time it around the Big 3, but thankfully I choose to be flexible on my journey to beat down my MAI. Thank
you very much, Terri

@terrimn I have used the NOW Brand, but was unhappy with the last order - was very close to use by date when purchased. Not using it now, but when I do, it will come from the supplement section at our local Co-op, where products move quickly and they are picky about the products.

@terrimn I purchase mine online from Swanson Vitamins. I'm very happy with the quality.

When I could not source from Jarrow due to some FDA change a few years back, Jarrow referred me to Life Extension. I purchase other supplements from them also and have been very happy with quality and service.

Yes. For me it works like aspirin for migraines but without any of the side effects. It used to be prescribed to reduce oral inflammation. It was made from silkworm bacteria, but now is produced from algae. It's been around a long time, first as prescription only. I think it might be underrated as a safer anti-inflammatory than popular NSAIDS, probably because research results have not been steller (it might have a mild effect) and there is no money in it. It is worth trying in place of NSAIDS. and best if taken on an empty stomach.
