This Indian study aimed to assess the efficacy, tolerability, and safety of vitamin K in patients with peripheral neuropathy (conditions that involve damage to nerves outside of the central nervous system). The study was conducted on 100 patients with peripheral neuropathy who suffered from vitamin B12 deficiency or type 2 diabetes mellitus. The patients received vitamin K capsules (200 mcg/day) for 8 weeks and were followed up to the 12th week. The intensity of symptoms was assessed using a pain rating scale (Visual Analog Scale). In week 12, results showed a significant reduction of pain in both patients with vitamin B12 deficiency and type 2 diabetes patients. In conclusion, vitamin K supplementation was shown to have potential therapeutic effects on the symptoms of peripheral neuropathy. Further details can be found in the study.
