N-A-C (N-Acetyl-L-Cysteine) - 120 Capsules

I was having an asthma episode for a number of days and started taking N-A-C and the symptoms subsided over a number of days.

One of my good friends is a pharmacist, he implored me for lifestyle reasons to take NAC everyday.
Right away I found myself more energized and refreshed, I was using it for liver health. However over time I realized I was no longer getting my twice yearly bouts with Bronchitis, I have not had Bronchitis in 7 years. I no longer use my Symbicort inhalers either. My lungs are fantastic and at 63 can hike the Arizona trails for up to 3-4 hours.
I have not had a cold either in that time, so I believe NAC is a wonder drug. It is used at hospitals as the first line of defence against acetaminophen overdose. It is on the WHO list of products that one should be taking daily.
