I have had other brands that were more expensive than this brand so I was a bit skeptical of the quality, however, I have no complaints with the purpose for which I purchased this Life Extension N-Acetyl-L-Cysteine (NAC) for. I have beginning stages of emphysema and COPD so when I get sick with a cold it always goes into my chest and I get bronchitis often times having to go to the doctor. I use this at the first sign of a cold, and can more often than not, can escape the bronchitis and the doctor. I have had one cold since purchasing this and it worked as hoped. This will be my go to brand for N-Acetyl-L-Cysteine (NAC) as the price is good and the product works. Recommended! Read more
