It has been hypothesized that idiopathic carpal tunnel syndrome (CTS) is a manifestation of vitamin B6 deficiency. Some claim that B6 supplementation can alleviate symptoms. Others argue that pain relief occurs because of vitamin B6's anti-nociceptive properties or because B6 supplementation addresses an unrecognized peripheral neuropathy. Few studies on CTS and B6 employed electrodiagnostic techniques in diagnosis, and few showed a correlation between symptoms and improved electrodiagnostic parameters with supplementation. Other studies failed to measure or estimate B6 levels. Nevertheless, it appears reasonable to recommend vitamin B6 supplementation to people with CTS. Some patients will improve symptomatically with low risks of toxicity in recommended doses.
