Effect


Shortage

The most common cause of a shortage of vitamin B12 is a disturbed uptake in the gastrointestinal tract. People who don’t use animal products for a long time, such as vegans, can also develop a vitamin B12 shortage.

The symptoms of a shortage of vitamin B12 often occur only after years, because the body pulls up a stock of this vitamin. A vitamin B12 shortage causes a form of anemia, with symptoms such as fatigue, difficulty breathing, angina pectoris (chest pain) and loss of appetite. In addition, a shortage can affect the nervous system, causing tingling in the fingers, parestesia, memory loss, coordination problems and muscle weakness in the legs. The elderly may have problems with their memory as a result of too little vitamin B12.


Overdose

There are no known adverse effects to the body of a high vitamin B12 intake. The body itself can, in case of a high intake, reduce the uptake of vitamin B12 from food.
