Before we look at the main symptoms of vitamin b12 deficiency, let’s first look at what is vitamin b12 and why we need it.
What is vitamin B12?
Vitamin B12 is an essential vitamin that plays an important role in the synthesis of red blood cells and DNA. It is also important for the normal functioning of the nervous system.
What causes vitamin b12 deficiency?
Vitamin B12 deficiency occurs because of two main reasons.
The body does not make vitamin B12. We get our vitamin b12 from our diet. It is present mainly in animal-based products so those following a vegan or strict vegetarian diet are more likely to be deficient in vitamin b12.
Secondly, some people are not able to absorb vitamin b12 from the food they consume due to either some health conditions of the digestive system or because of some types of medicines which can reduce the absorption of vitamin b12.

Tiredness
Those suffering from vitamin b12 deficiency can experience extreme tiredness. Some people may also feel that they lack energy.
This is thought to be linked with reduced numbers/function of the red blood cells to carry oxygen which is required for the normal functioning of the body.
