Question 4

why would ihave low vitamin b12?

Accepted Answer

Possible causes: You could have a low b-12 if you are vegetarian, have been for several years and don't take supplemental b-12.  It could be low if you don't make intrinsic factor.  This is made in the stomach and is needed to absorb b-12.  Lack of intrinsic factor is usually an autoimmune disorder.  You could have low b-12 due to taking proton pump inhibitors for a long time as stomach acid is needed as well.
