Top rated brand

My General MD stated that I should take NAC along with Milk Thistle for liver health. This particular brand was top rated, and affordable. I noted that if taken at night, they work to prevent "inflammation and mucus clearance." If taken during the day, they work for "athletic performance and increased energy." They are versatile and can be taken to suit your needs. No taste, easy to swallow.

Less coughing!!

My sister uses this for her breathing issues and gave me some because she's doing more, wheezing less. I found, being a long time smoker and lots of coughing, that not only am I coughing less but it's also a much more productive cough when I do! Very pleased with this supplement and I'll keep ordering.
