Anyone take vitamin N-acetylcysteine (NAC)

I went to a NAMI meeting yesterday and the presenter mentioned the vitamin NAC. After doing a google search I see that there have been some legit studies about its affects on SZ and inflammation. Has anyone on here tried this and if so was it helpful?

I tried it by itself and it didn’t do anything, however I started taking a product called ProFrontal which is NAC + sarcosine and it seems to have a synergistic effect and worked much better that straight sarcosine.
