Lots of this type of product on the market all making similar claims. Looking at the ingredients, it does contain supplements and vitamins that have shown to help with nerve pain. I'm a little cautious as to the quality of the ingredients they use in their proprietary formula. What makes me even more cautious is the advertising around the product and the miracle claims being made.

Most of the ingredients listed on several different websites advertising Nerve Savior are listed on the Foundation for Peripheral Neuropathy on the list of complementary and alternative treatments here (shown at the end of the document) - https://www.foundationforpn.org/wp-content/uploads/2020/08/Complementary-and-Alternative-Treatments-Revised-2020-final.-1.pdf.
