Hi @fenn47, I've been taking R-ALA since 2016 as part of my supplements for neuropathy but I don't have pain with my neuropathy. I haven't noticed any hair loss but it's not getting any thicker at 81 🙃. The Foundation for Peripheral Neuropathy has a list of supplements that have shown to help neuropathy symptoms in their Complementary and Alternative Treatments document here - https://www.foundationforpn.org/wp-content/uploads/2020/08/Complementary-and-Alternative-Treatments-Revised-2020-final.-1.pdf.

There have been other Connect members who have posted about different side effects. Here's a link that lists the comments if you want to scan through them - https://connect.mayoclinic.org/search/?search=ALA+side+effects.
