Vitamin B12 (cobalamin) is a compound whose deficiency in the human body causes significant hematological, neurological, psychiatric and gastroenterological disorders. In particular, elderly patients are exposed to vitamin B12 deficiency. It is believed that the problem of cobalamin deficiency in the population is undervalued. Common causes of that hypovitaminosis are: insufficient supply, impaired release from the binding protein in gastrointestinal tract, and Addison-Biermer disease. Proper level of cobalamin in the serum and reducing the clinical signs of deficiency can be achieved by enteral and parenteral replacement therapy and food supplementation.

Key words: vitamin B12, elderly people, diet, Addison-Biermer anemia.
