I've been taking R-ALA as one of my supplements to help with my idiopathic small fiber PN since 2016 and feel it has helped slow, maybe stopped the progression of my neuropathy. Hasn't helped with the old age and balance though 🙃. I shared my neuropathy journey in another discussion here - https://connect.mayoclinic.org/comment/310341/.

Also, the Foundation for Peripheral Neuropathy has quite a bit of information on chemo induced neuropathy that you might want to scan through to see if something might be helpful - https://www.foundationforpn.org/.
