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.

Great product for allergy season
NAC clears/detoxes my liver, especially during allergy season. It especially helps with my eye sun-sensitivity during allergy season, which then leads to less sneezing!
