Your overall energy, concentration, focus and memory are affected by your levels of vitamin B12. Vitamin B12, also called cobalamin, is needed, among other things, for the cells' metabolism and for the formation of red blood cells. It is also necessary for the functioning of the nervous system.
If you are in a risk group for B12 deficiency or if you experience symptoms that may be due to vitamin B12 deficiency, such as headaches, fatigue, difficulty concentrating or dizziness, it may be a good idea to test your B12 levels. Lack of vitamin B12 can lead to a type of anemia called megaloblastic anemia which results in fatigue, weakness and paleness. Since B12 also affects your nervous system, a deficiency can cause numbness and tingling in the extremities, balance problems, memory problems, depression, confusion and other neurological symptoms. In addition to the above, b12 deficiency can cause fatigue.
Vitamin B12 occurs mainly in animal products such as meat, fish, shellfish, dairy products and eggs. This means that people who follow a strict vegetarian or vegan diet are at higher risk of B12 deficiency. It is therefore of extra importance to monitor B12 levels and possibly take supplements provided the analysis shows low values.
