N-Acetyl cysteine is a stable form of the sulfur amino acid L-cysteine, and is a powerful antioxidant. It is also a precursor of glutathione, a major antioxidant. Glutathione is activated by the selenium-containing glutathione peroxidase, one of the most important antioxidant enzymes in the body. N-Acetyl cysteine is better than glutathione supplements, which may break down during digestion and lose potency.

I have been taking NAC for months now, and I appreciate the larger 1 gram size, also need to up my vitamin c dosage to 3 grams with this monster, otherwise it can cause more bad than good. Strong sulfur odor lets me know it means business.
I have/had a 30% hearing loss from family genetic predisposition. I've been taking this supplement for 3-4 months now and I believe there has been definite improvement. Maybe a 10%-15% reduction. I've stopped using my hearing aids and though I still have trouble hearing I'm picking up much more conversation than I did in the past. I'm 54 but I think this is definitely worth a try. This substance was supposedly tested by the US Navy to help prevent hearing loss onboard ships but it has also helped me.

I have been using this product now for 8 months, after my doctor suggested taking this with my anti-depressants. I feel so much better.

Very difficult to swallow - even after breaking it in half.
Great immune system booster

I've been using this product daily (2,000mg) for over two years and have had hardly any respiratory infections over that period. It's a great immune system booster. Highly recommended.
Cured my horrible 4 months cough
Posted by 5040988076438410898 on May 27, 2016
I had a cold that just would not yield from Christmas to April. I was on antibiotic (doxycycline) for 2 weeks during this time when the cold vanished. As soon as I got off the antibiotics the cold came back with vengeance. I had actually ordered this stuff for my dad who has early parkinson's disease so I popped a pill of 1000 mg N-acetylcysteine just to show him that it is safe to take. Within an hour I started to cough up phlegm like there was no tomorrow. It felt as if I coughed up stuff from my throat that had resided there for years. Anyway, I went to bed and woke up cured from my cold. AMAZING! I decided to keep taking it to make sure the cold/cough did not return. It didn't. I have kept taking it since then. My dad also takes 2 per day (morning and night) along with his parkinson's medication (dopamine) and he has become much less fatigued with this supplement - he felt a difference on day 2.
