It is dangerous. About a week after starting NAC, I experienced pressure in my left chest and difficulty breathing. I did not take any other supplements, so this product seems to be the cause. There are concerns about it causing grey hair, suggesting it may contain harmful ingredients. I will not take it again.

Worth a go. I've found that it has helped with chest tightness, allowing me to use my relievers less frequently after a particularly tough asthma season.

I consulted with an internal medicine doctor who mentioned a substance that dissolves the mucus in the chest. However, it's harmful as it dissolves substances on the stomach wall. It also makes me drowsy, so I will stop taking it.
