Nutricost N-Acetyl L-Cysteine (NAC) Powder 250 Grams - Vegan NAC, Non-GMO, 208 Servings

This was recommended by a doctor for me to use in a nebulizer. I'm getting excellent results. I've never heard of it before and don't know what else it is used for. But it clears my sinuses.

So looking at the other reviews, I feel I need to lead with the most important thing. NAC has an incredibly harsh taste that is very hard to cover up. If you're sensitive to sour/bitter, I'd recommend putting this in capsules. I'd say the flavor is akin to like a warhead candy, but with some bitter notes and it doesn't subside until you swallow it. It doesn't bother me though for the amount I save buying in bulk. That being said, I have found some things that help; for me I dump the scoop onto the back of my tongue and then drink immediately; I found coke zero actually seemed to cover the taste a bit. Coffee on the other hand was an incredibly bad choice and somehow seemed to make the flavor stronger. I haven't tried mixing it in anything because I can't imagine they're may things out there that could cover up a flavor like this. As for the effectiveness, like with any supplements, look for a study confirming it can do what you want it to do, as well as the dose used in the study. I don't want to get into specific medical conditions, but that's what I did to figure out what dosage to take (was more than this product recommended) and it seems to be helping.

Excellent product.

Tastes fine. Disolves in warm water, but not cold. More for less than capsules. I take with cold water, and add a little more water to finish off the residual. I also drink it to take other capsule supplements at the same time.

It's my understanding that taking glutathione on its own doesn't work. You need a precursor like this. This is also 500 doses! Tastes like lemon rind. I just put it in a drink.
