Vitamin B12 is very important for our body and 2.4 micrograms of vitamin B12 is required daily. But did you know that even this small amount of deficiency can put the body in extreme danger? B12 is one of the 8 B vitamins that the body needs for normal nervous system function. Vitamin B12 is only available from meat, eggs, and dairy products, as plants do not make it. Sometimes the symptoms of Vitamin B12 deficiency can be confused with something else, so it is better to get it checked by a doctor.

People who have vitamin B12 walk with wide legs. This unsteady walk can be a sign of other health conditions, but peripheral nerve damage due to vitamin B12 deficiency affects a person's movement. A person may also feel numbness in his feet and limbs, which also affects his natural movement. Apart from this, a swollen tongue can also be an early sign of Vitamin B12 deficiency. A swollen tongue with straight long sores is a good sign of Vitamin B12 deficiency. In this condition, the tongue is often red and there is a feeling of prickling along with it.

Depression
A 2018 study found a neurological link to vitamin B12 deficiency. The person on whom it was studied had lost his memory, could not make decisions, and his personality had changed. He could not bear to think about it and he lived in depression.

Fast heartbeat
Many health reports say that a fast heart rate without any other reason is a sign that there is not enough Vitamin B12 in the body. Dil makes up for the low number of red blood cells that occurs when there is a deficiency of Vitamin B12 in the body. This puts extra strain on the heart to pump more blood into the body.
