hi pabb,
thanks for the reply, im only 29, so the changes of life shouldn't be here yet. i do have heavy menstrual bleeding, which i believed caused the low ferritin, just don't know why my b12 is only 296. my doctor isn't a help and looks at me like im crazy whenever i tell her of my symptoms. so perhaps i should try the b12 oral supplements and see what happens. i know it's important to find an underlying factor, but i just don't know how to get through to her.

also can people have low b12 just do to the fact that they don't eat meat regularly? i know vegans have this problem sometimes. i do eat meat, but not that often, maybe 1-2 times a week, sometimes none.

thanks for the advice!
