NAC = N Aceryl Cysteine. It is supposed to help with phlegm as Jean said.

Where did you here about NAC ? Myself I take Boost , B12 , D, C, maybe a shot of brandy once a day , not the whole bottle ha ha . Never give up . John .

Hi I look that NAC up on internet it for liver function. Before taken antthink check with Dr or research it.also have you blood checked . I hope my info, ok.

It's a mucolytic that helps with mucous by making it thin and easy to cough up. Mucinex does much the same thing. If you have problems with mucous, NAC can probably help.
