What is Vitamin B12

Vitamin B12, known as cobalamin, is part of the vitamin B complex. This complex is involved in many processes in the human body: helps produce energy, and supports the functioning of the musculoskeletal system, circulatory system, nervous system, digestive system, and immunity.

This vitamin is not naturally produced by the human body, and chemically speaking, B12 is one of the most complex vitamins. To be absorbed in our body, cobalamin needs special processing in foods in the stomach. Here, animal protein gets in contact with gastric acid and enzymes, then releases vitamin B12.

The released molecule combines with another substance secreted by the stomach cells, called intrinsic factor, which allows it to be absorbed in the small intestine then to be transported through the blood in the liver, then to all body cells.

Vitamin B12 Deficiency Symptoms

Cardinal symptoms of vitamin B12 deficiency:

  • Anemia;
  • Neuropsychologic problems (fatigue, focus, and memory disorders, tingling sensation, mobility changes);
  • Digestive symptoms: mild diarrhea and glossitis;

Once absorbed in the body, vitamin B12 is stocked in the liver, where is progressively released according to your body’s needs. In its absence from the diet or in case of any chronic affection which affects its absorption, the symptoms of vitamin B12 deficiency will be felt after a few years.

In advanced stages, a lack of B12 leads to Biermer anemia or pernicious, an auto-immune disease which is manifested by:

  • Megaloblastic anemia, a feeling of fatigue and weakness, dizziness, headaches, and breathing difficulties;
  • Gastrointestinal symptoms: mild diarrhea or constipation, digestive and urinary incontinence;
  • Neurological symptoms: focus or memory problems, sensorial and motor disorders.
