I asked my neurologist about ALA and he looked it up on his computer with me. (I had already researched it online.) Has he never heard of it? Then he said without regulation you never really know what supplements contain so he wouldn't recommend taking it. I took ALA for two months, but didn't notice any difference in my neuropathy so I stopped. I have idiopathic neuropathy and I think (but don't know for sure) ALA helps diabetic neuropathy more.
