Yeah the smell is bad and taste is not good either but mixing it in strong tea makes it OK. I use it whenever under stress and if I feel like I might get sick, I take several doses a day. Seems to work as I had several times I felt I might get sick, took a lot of cystine and was OK the next day.Goes Well With:other antioxydants

Report this reviewN Acetyl L Cysteine
It's hard to say if N Acetyl L Cysteine has been effective as it is purely used as an antioxidant. Be prepared for a very acidic taste, I use it with dispersible Vitamin C tablets for extra effect and improved taste.

Report this reviewSour
This stuffs stinks really bad! Mixes easily in liquid, it’s very sour too. I mix it in a small glass in a tiny amount of water and just gulp it down in one. If it’s doing good for me I don’t mind.
