I had never heard of Neurobion so I had to look it up. Neurobion is a multivitamin which I am sure you are aware. Did your doctor test your vitamin levels in your blood serum? Were you found to have specific deficiencies? If you are in need of vitamin supplements, then treating that deficiency should help you feel better indirectly. I don't know how much this will affect your RA, but I would talk to your doctor and ask any him/her any questions you may have after reseraching Neurobion.
