Malabsorption: B12 is readily available in foods of animal origin (including dairy & eggs) so unless one is vegan you'll get enough via diet unless you can't absorb it; this can be caused by low hydrochloric acid, overgrowth of yeast or bacteria in the small intestines or a hereditary condition called pernicious anemia.Take methylcobalamin orally or by injection.
