Hi @stormpassing, I haven't seen any mention of NAC for neuropathy but a quick search of Connect lists a couple of discussions in other groups on N-acetylcysteine (NAC) that might be helpful while you wait for other members to respond.

-- NAC supplement?: https://connect.mayoclinic.org/discussion/nac-supplement/
-- Taking N-acetylcysteine (NAC) for COPD: Does it help?: https://connect.mayoclinic.org/discussion/taking-nac-for-copd/

There does seem to be some research on the supplement:

Do you mind sharing how you heard about the supplement? Did you see some research?
