@hossie, I've heard a few members mention it in older discussions but I don't think I've seen any evidence-based studies about their treatment protocol. Similarly, there were no results in the research database on PubMed https://www.ncbi.nlm.nih.gov/. Their original website is no longer active (http://blueprinttoneuropathy.net/) and I think this is the new one but it also has no evidence-based studies about their protocol other than their claims on the website here - https://blueprintnutrition.com/education/neuropathy/.

There are a lot of supplements that have research and studies supporting their use all of which I've seen listed here on the Foundation for Peripheral Neuropathy's website in the Complementary and Alternative Treatments document - https://www.foundationforpn.org/wp-content/uploads/2020/08/Complementary-and-Alternative-Treatments-Revised-2020-final.-1.pdf.

Early on I looked into treatment at a neuropathy clinic and decided against it because it was a lot of money over many treatments with no guarantees. That and I could find no evidence-based studies that it might work or help. I would proceed with caution. Ask questions, hard questions about scientific evidence before paying loads of money.
