"The amino acid acetyl‐L‐carnitine (ALC) plays a role in the transfer of long‐chain fatty acids into mitochondria for β‐oxidation. ALC supplementation also induces neuroprotective and neurotrophic effects in the peripheral nervous system." https://pubmed.ncbi.nlm.nih.gov/31201734/.

The Foundation for Peripheral Neuropathy has a list of supplements known to help with neuropathy at the end of their list of Complementary and Alternative Treatments here - https://www.foundationforpn.org/wp-content/uploads/2020/08/Complementary-and-Alternative-Treatments-Revised-2020-final.-1.pdf.
