Therefore, the deficiency of this substance should not be underestimated. In order to prevent this from happening, it is necessary to understand the underlying reasons for a possible lack of vitamin B12 within the body. One of the first causes could indicate an absorption problem due to the gastrointestinal system that does not allow to fully assimilate the properties of the vitamin.

Therefore, not meeting the daily requirement of this vitamin could have serious health consequences.

First of all, since vitamin B12 is essential for the synthesis of red blood cells, any deficiency could cause the appearance of anemia with a consequent decrease in the amount of red blood cells. This process can also cause various symptoms such as fatigue, low blood pressure, hypotension, reduced reflexes and paleness. Furthermore, the lack of vitamin B12 can cause nervous system disorders with difficulty in the movement of arms and legs. Difficulty speaking, walking and spasms may also occur. Currently there have been no side effects and contraindications related to an excessive intake of vitamin B12.
