No one has replied to this thread for a while, so I'm not sure if anyone is still checking it. But I was searching for something else and came across this thread. Here are my two cents:

Yes, there could be a connection to premature graying of the hair and B12 deficiency. But the likely connection may lie in a hidden folic acid deficiency, which can cause graying of the hair. B12 issues can often mask a folic acid deficiency, so make sure that you get that tested right along with the B12. I actually have had a B12 deficiency for years, on and off, and only recently discovered the folic acid deficiency through my smart GI doc who knew to keep looking. Despite the fact that my dad and mom both grayed much later in life (in their late 40s/early 50s) I had found a few silvers on my own head (I'm in my early 30s), which was really shocking for me- I plucked them out! Now that I'm on folic acid supplements, hopefully my normal color will return. And hopefully yours too!
