Vitamin B12, also called cobalamin, is involved in cell division processes and is necessary for the whole organism: nervous system, blood vessels, blood, mucous membranes, and skin. A decrease in vitamin B12 indicates poor nutrition, disordered function of the digestive system, and disorders of the nervous system.

Good to know

Vitamin B12 deficiency is often found in vegetarians and vegans, because it is more difficult for them to get this vitamin from food.

Preventive tests are recommended for those who have or have had hepatic, pancreatic, or digestive system diseases (coeliac disease, Crohn’s disease, or irritable bowel syndrome), diabetes, following stomach cancer or stomach reduction surgery, those who regularly consume alcohol and who are above 50. With these conditions, absorption of vitamin B12 is often irregular.

Pregnant and nursing women, people who are under extreme pressure at work and who are constantly stressed, and children in periods of intense growth need more vitamin B12.

The most common symptoms are:

  • fatigue;
  • lack of energy.

Less frequent symptoms:

  • changing moods, jitters;
  • thinning, falling hair;
  • pale, yellowish, greyish skin;
  • muscle weakness and pain;
  • equilibrium disorders;
  • vertigo;
  • disturbed vision;
  • mouth sores;
  • tingling, numbness in the extremities.

The human body can store B12 for 2–5 years; consequently, you will only feel the latter (rarer) symptoms if the vitamin B12 deficiency has persisted for a long time. 

Scientific research shows that long-term and significant vitamin B12 deficiency influences the development of the following illnesses:

  • anaemia (iron deficiency);
  • concentration and learning disorders in children;
  • infertility;
  • depression;
  • Alzheimer’s, dementia;
  • autoimmune diseases (e.g. rheumatoid arthritis);
  • cardiovascular diseases;
  • cancer.
  • Your test results will be ready within 1 day.
    You can pick them up at the reception or, if you wish, we will email them.
  • For an explanation of test results, you should call the laboratory tel. (+370) 247 64 17.

FAQ (frequently asked questions)

Your body does not produce this vitamin; you must get it from food. Foods rich in vitamin B12 include meat (especially beef loin and liver), fish (especially salmon, tuna, and trout), eggs, oysters, mozzarella, and skimmed milk.
When vitamin B12 assimilation is disturbed or the need for it has increased due to the abovementioned factors, vitamin supplements should be taken after consulting with your physician

Healthy people need 3–4 mg of vitamin B12 daily. You can get this amount by eating one portion (~150 g) of the abovementioned products per day.

Together with the vitamin B12 test, it is generally recommended to have a folic acid test carried out, seeing that these two are linked: vitamin B12 activates folic acid.
