Vitamin B8 plays an important role in the processing of carbohydrates and proteins and the production of fatty acids. It contributes to the energy supply. Vitamin B8 is also important for a properly functioning nervous system, for healthy hair and a healthy skin. Vitamin B8 is part of the vitamin B complex.


Vitamin B8 is found in many different foods, including eggs, milk, soy products, nuts and peanuts. In addition, bacteria in the large intestine are capable of producing vitamin B8.



A shortage of vitamin B8 is rare, because this vitamin is present in a large number of foodstuffs. If there is a shortage anyway, symptoms occur such as skin defects, tongue infection, poor appetite, fatigue, muscle pain, anemia and depression.


There are no known adverse effects of a high intake of vitamin B8. Who receives more vitamin B8 than he or she needs, pees out the surplus.
