I did a bunch of research when I was first diagnosed and the vitamins I thought had promise were: vitamin C, fish oil, vitamin D, vitamin Bs, MSM, glucosamine, chondroitin, vitamin E, and lipoic acid. I take all of them except lipoic acid. I really think the fish oil helps with inflammation, but it requires a high dose (though be careful to not take too much). Also, be careful with taking too much vitamin E - I took the max and it increased my migraines, so I had to cut back.
