I hesitated to mention the specific supplement for that reason, but maybe it will help someone. Apparently, the glutamate-glutamine system is implicated in psychiatric problems. Through my research I found that GABA deficiencies can cause ADHD symptoms. GABA is produced in the gut, I have stomach problems, so this seemed feasible. I learned that NAC increases glutathione and helps regulate glutamate. The effects people report point to an effect on this system. The Wikipedia page for NAC has many references, but this is one review of its possible uses in psychiatric problems: https://www.sciencedirect.com/science/article/pii/S0149763415001190 https://www.sciencedirect.com/science/article/pii/S014976341... https://en.wikipedia.org/wiki/Acetylcysteine https://en.wikipedia.org/wiki/Acetylcysteine
