Low ferritin 5.5 & b12, 241 my doctor isn't concerned? would a daily multivitamin help rise these or do i need to take something for both of these?

More than that: Ms. Blum, based on this and an other question, you need to be treated for your nutritional deficiencies. If your current doctor is not responsive, it is appropriate to see a different doctor. It may be that your intake is insufficient or that your intestines do not absorb nutrients properly, in either care consulting a gastroenterologist would do you good.
