    N Acetyl Cysteine

    This seems to be a good product .My only issue is it would be a lot easier to figure out a dosage if a scoop was provided.

    tastier nac

    Is used medically, to break up mucus and works extraordinarily well. Great for anyone suffering asthma or broncitis. It can be made more palatable mixed with vitamin C , orange or pomegranite juice etc. is effective when broken down into smaller doses besides the recommended 200mg per serve.. . ie 2 x 1000mg rather than downing 2000 mg in a single dose. This makes helps make it more palatable also.
