What owners say about NAC (N-acetylcysteine)

4/5 Feeling flat or numbMood

“NAC, worked very well in the first weeks as in major improvement for ADHD symptoms but after a while I started getting anhedonia/depression. Currently doing 1-2x a week 600mg and it seems to have mild positive effects and no side effects”
