If you have asthma, COPD, chronic bronchitis or as soon as you feel like you cold is going to your chest, take it!!!!! Have chronic allergy problems that always wind up in my chest. Started taking 2 per day for a couple of weeks to aid with breathing. Haven't been able to blow up a balloon or pool float for yrs. w/o feeling dizzy! Was amazed this past summer as I was able to blow up multiple pool floats at a time! It was the only product I was taking so I know it was N-Acetyl Cysteine that helped. I have experimented a couple of times with this product to see how long the results last and to make sure it was the product that helped. Each time I took it, I had positive results! Highly recommend for anyone who has breathing problems. Safe, inexpensive and it works!


I take this for anxiety and to help my brain recover from concussions. I’ve never been prescribed anything for my anxiety as it takes too long or I don’t actually follow through. I heard about this supplement and for $10 my compulsive anxious thoughts and behaviors are quieted. I truly think that this works. I noticed a difference the same day as my head wasn’t racing with thoughts (I wake up at 5 in the morning bc of this). I just really wish the pills weren’t so big. My fault, I could’ve ordered powder, but the convenience is nice.

L-cysteine seems to alleviate, not cure, my lifelong nasal allergies.
