The importance of vitamin B12 for the human body is comparable to oil for a petrol engine. If the petrol engine is running out of oil, it slowly but surely enters destruction.

When following a regular, balanced diet, you will have an adequate intake of vitamin B12. However, the absorption of vitamin B12 works often not properly. This can have various reasons: gastrointestinal tract disorders, medication, errors in metabolism and alcohol consumption are the most important.

Vitamin B12 is essential for the human body. It has an important role in the functioning of the nervous system, the immune system, oxygen transport, cognitive brain functions, the production of red blood cells and the formation of DNA, an energy-supplying metabolism, which reduces fatigue and exhaustion.

This is why symptoms of a vitamin B12 deficiency are so diverse and extensive. The most common symptoms are fatigue, memory loss, difficulty concentrating, loss of appetite, always feeling cold, depression, psychological problems, allergies and neurological complaints.

Two types of active Vitamin B12 can be absorbed directly by the body, so you can be sure that it works: Methylcobalamin B12 and Adenosylcobalamin B12 (dibencozide). If you take these types of vitamin B12 in the form of lozenges, they will enter the bloodstream directly through the oral mucosa.
