Vitamin B6 is important for the immune system and digestion. It plays a role in the development of red blood cells. It is also important for the energy supply and ensures the proper functioning of the nervous system. Vitamin B6 is part of the vitamin B complex.


In food, vitamin B6 is usually bound to proteins. It is found in meat (especially chicken and liver), eggs, fish, cereals, potatoes and legumes. Vegetables, milk and cheese contain vitamin B6 in smaller amounts.



Prolonged severe shortages can lead to anemia, nerve diseases, reduced immune system, inflammation of the tongue and skin, depression, confusion and fatigue. In infants, a lack of vitamin B6 leads to symptoms such as convulsions, vomiting and weight loss.


High doses of vitamin B6 can lead to defects of the nervous system. In addition, light sensitivity or a deterioration of memory and thought processes can occur.
