- The review's verdict came after noting that few studies used electrodiagnostic tests and that few showed nerve improvement with supplements. It is an expert judgment on mixed evidence.
- What it does not show
- This is an opinion from a 2004 narrative review, not a trial result. A 1993 placebo-controlled trial of 32 people, which the review predates, found no difference from placebo.
