N-acetylcysteine (abbreviated as NAC) is a compound that is found naturally in the body. It is a precursor to a chemical called glutathione, which plays a large role in detoxification of foreign substances in the body. NAC itself is a strong antioxidant; it can neutralize free radicals that damage DNA and cells.

    I use about about 150 mg twice / diem always take w/ some vitamin "C"

    Posted by Swimmingfool on 13th Jun 2015

    This is a fantastic adjunct to my pre-workout formula. I serves to de-obstruct the pleura and counteract mucous buildup from whey protien powders and mucous causing foods that can overburden fluid metobolism. I furiously swim 5 miles openwater / cold water (in summer) per day and cannot afford getting crapped up. So, if used wisely it will really help you keep the pipes clear!. Be carefull , go easy unill you find your balance. Some heavy lifters report blown out mucous membraines, but I think that they way over do it. I use this with spirolina, 100 mg betaine, ascorbic acid and a few grams arginine, inositol, BCAA's, malic, citruline, B-5, B-12, etc. in a tea/ juice/ probiotic innoculated chia seed cocktail pre- work formula which follows a whey protien shake by an hour or so. If I am carefull, the blend is very incredibly tasty, then I know I got it right. I hope this helps to de-mystify this substance for that guy who bought a couple pounds of this. Really unimaginable! That can't be accurate. He must have meant ounces, right? Right!

    Great Product and Company

    The taste cannot be described as good, but that is a testament to the fact that you are purchasing pure product here rather than product cut with filler and flavoring. I believe it has a high sulfur content, that is where the smell and taste come from. Most products I have gotten here have a milder smell and taste, but if you are serious about getting pure product at lower cost per serving this is where you want to get it. And as mentioned, you can also cap the product to avoid the taste, I just bought their capping machine and have used it for 2 other products. I always look to buy products here first, have about 30 of their products currently in use, just picked up another 2 lbs of NAC as I was running low.

    Great Service

    Fast shipping, good price, powder seems legit, though NAC is too subtle to really know.

    I don't understand the review stating that this powder was gross. Some powders have no taste, like creatine, but many do taste 'chemically'. That has nothing to do with the quality of the product, and may just mean that you need to put it in capsules.

    I actually don't find the taste bad at all. Compared to almost unbearable powders like alpha lipoic acid or PEA, this is absolutely delicious.
