Improved breathing
6 people found this helpful
Very great! I had a persistently congested chest from smoking and just two days after starting this wonderful supplement, I was able to sleep again without being troubled by the wheezing in my chest. My breathing is much better now, and I can't live without it anymore. I have tested other brands, but this one had the best effect.

No more night waking

I always buy this! After beginning to take this supplement, I no longer wake up at night and can enjoy better sleep. It appears to have detoxifying effects and is rich in antioxidants, which is why I continually use it.

Fewer obsessive thoughts
5 people found this helpful
Certainly, I’ve noticed fewer obsessive thoughts after about two weeks of taking it. I don’t feel my head is clearer yet, but I believe I’m sleeping more soundly. I take it with glycine to boost glutathione production, which may enhance my sleep quality even further. Regardless, it’s a very good supplement, as I feel more relaxed.

Better sleep quality
Great stuff! This high-quality supplement significantly improved my sleep and alleviated my respiratory allergy symptoms. Although it smells unpleasant, that’s just how NAC is; it doesn’t leave a bad taste in my mouth. I’m buying it again.

Improved sleep quality
I took it to strengthen my cardiovascular system, taking it in the morning after meals with omega-3. The results were gradual, but a side effect was improved sleep. If this was useful, please click like.

Still testing effect
Very good. I started taking it one day earlier than scheduled and have taken it for two days. One of my main reasons for purchasing was that it helps with sleep, but I don’t feel an effect yet. I will continue taking it as research suggests it will be effective.
