The body requires vitamin B12 to function. It aids in the development of red blood cells and the maintenance of healthy nerve cells. One of the causes of a vitamin B12 deficiency could be a problem with the stomach's ability to properly digest the vitamin.
Water-soluble vitamin B12 is offered as a dietary supplement, a prescription drug, and is naturally present in some foods and added to others. Compounds with vitamin B12 action are collectively referred to as "cobalamins" since vitamin B12 contains the element cobalt.
The synthesis of DNA, healthy red blood cell creation, and the growth, myelination, and operation of the central nervous system all depend on vitamin B12. Before it can be absorbed, vitamin B12 that is attached to protein in food must be released. When saliva and food are combined in the mouth, the process begins. The cobalamin-binding protein haptocorrin in the saliva then binds with the vitamin B12 that has been released.
