Uncommon symptoms that indicate low levels of vitamin B12​

Our bodies require 2.4 micrograms of vitamin B12 daily to perform vital functions such as nerve, DNA, and red blood cell synthesis. Our bodies cannot produce vitamin B12 on their own to perform these functions, so we must meet our needs through food and supplements. If you don’t get enough vitamin B12 through food, your body will react to vitamin B12 deficiency in several ways. Here are some rare signs of vitamin B12 deficiency.

One of the classic signs of vitamin B12 deficiency is numbness in the hands and feet. It is caused by peripheral neuropathy, in which nerves are damaged. Vitamin B12 plays an important role in the production of neurotransmitters, and vitamin B12 deficiency affects neurotransmission.

People with extremely low levels of vitamin B12 have difficulty walking properly. This is also the result of peripheral nerve injury. Numbness in the limbs, especially the feet, makes it difficult to walk normally.

A lack of vitamin B12 causes glossitis. The tongue is swollen and discolored. It looks more red. Some people also experience an unexplained itching or burning sensation in their mouth.

Vitamin B12 is directly related to mental health. This causes cognitive impairment and affects an individual’s ability to reason and think, largely due to disruption of neurotransmitters. Memory loss is a classic symptom of vitamin B12 deficiency that many people ignore.
