How Important is Vitamin B-12

B12, or cobalamin, is an essential vitamin for the proper functioning and development of the brain the nerve cells ,body defense mechanisms, or red blood cell formation.

It plays an important role in the maintenance of the sheaths that cover and protect the nerves of the central and the peripheral nervous system, ensuring proper and faster nerve-impulse transmission.

Getting enough B12 allows your body to make heme, a chemical component of hemoglobin, the protein that transports oxygen in your blood.

Your body must constantly generate heme to make functional red blood cells, and cobalamin promotes this heme production.Vitamin B12 deficiency is not very common in young adults but older people are more prone to this condition.

Treating Vitamin B12 Deficiency Symptoms

A daily dose of 2.4 micrograms of vitamin B12 — from dietary sources or supplements is require to prevent a deficiency.
