I have a question regarding R-Lipoic acid.

My reading suggests that R-Lipoic acid may help small fiber neuropathy because it lowers blood sugar levels. That, in-turn, would help those with diabetic small fiber neuropathy.

However, for those with normal blood sugar levels AND idiopathic small fiber neuropathy, is it still helpful in both treating the burning and also rebuilding the small unmyelenated nerve fibers?
