Vitamin B12 is a water-soluble vitamin that is not produced by the body itself. Nevertheless, vitamin B12 has important functions in the body and that is why it is important that you get enough vitamins.
Keep energy levels healthy
For example, you need vitamin B12 for the production of blood and nerves. Vitamin B12 thus helps in the functioning of the nervous system. It is an essential vitamin needed to maintain healthy energy levels.
Food or supplements
Since your body does not make it itself, some people are more likely to have a vitamin B12 deficiency. That is why it is important that you get enough vitamins through food or supplements. Vitamin B12 is mainly found in meat, fish, milk, butter, quark, yoghurt and eggs.
Symptoms of a vitamin B12 deficiency

A vitamin B12 deficiency is insidious and it can take years for the symptoms to develop and become serious. When you suffer from a vitamin B12 deficiency, this can have consequences for all kinds of systems in your body, including the nervous system, immune system, cardiovascular system and gastrointestinal system.
