Vitamin B12 is a vitamin that contributes a lot to the body’s circulatory system. It plays a huge role in producing red blood cells, as well as DNA. Many don’t even realize that they are vitamin B12 deficient, until such time that the effects of a lack thereof worsen. Fortunately, experts shared how you would be able to identify vitamin B12 deficiency symptoms.

Those who are prone to suffer from vitamin B12 deficiency are vegans since most sources of this vitamin are animal foods. In fact, according to an Express’ report, many vegans in Britain are starting to worry that they don’t get the needed amount of vitamin B12. If you are also worried about the same, then take note of the symptoms that would help you determine if you are vitamin B12 deficient.

Vitamin B12 deficiency can cause anemia. This could then lead to symptoms such as feeling breathless. You may also feel dizzy. These feelings are the result of the body’s reduced ability to transport sufficient amounts of oxygen to various cells.

Changes in Mood

You might also notice how your personality would change without even a triggering factor. You may also start noticing that your memory has somehow become poorer. This is also an effect of being deficient in vitamin B12. Take note of these mood swings or poor memory.

Tingling and Numbness

According to the Head of Medicine Management at the Hospital group, Anjana Odedra, which had a survey of 2,000 adults in the UK, when vitamin B12 deficiency is already severe, it could lead to nerve damage. This could then result in numbness or tingling sensations in the body. The same could lead to a reduced sensitivity to pressure and pain.


Perhaps one of the most common symptoms of vitamin B12 deficiency, you may also feel tiredness or fatigue. Since a lack of vitamin B12 reduces the body’s ability to make red blood cells, then transporting oxygen throughout the body is also affected.

So if you experience any of these symptoms, better consult your general practitioner. You might already be suffering from vitamin B12 deficiency. You can try to look for foods that contain this vitamin. If you are a vegan, then you can opt for cornflake cereal and non-dairy milk.
