Before I found the Facebook group which started the Protocol 525, I was researching supplement that may help and was only taking Alpha Lipoic Acid and fish oil for the Omega 3 fatty acids but learned they are just pieces of the puzzle. I learned the "cheap" Alpha Lipoic Acid I was buying wasn't doing much for me since it was 50% S-ALA ( chemically produced in the manufacture of R-ALA and has less, if any nutritional value) so I switched to the higher quality 100% R-ALA. It was about that time in 2016 when I found the protocol which had the quality R-ALA as well as the fish oil as part of the list of supplements.

If you need a place to start, the Foundation for Peripheral Neuropathy has a list of supplements Most of these same supplements are part of the current Protocol 525.
