All about vitamins: vitamin B12

Vitamin B12, that is, cianocobalamin, is indispensable for the build-up of red blood cells and for metabolism.

Vitamin B12 is essential for cell division, cell growth, the production of red blood cells and for folic acid to get into the cells, but it also plays a crucial role in the production of DNA, RNA and the myelin sheath surrounding the nerve fibres.

Vitamin B12 is to be found mostly in food of animal origin, for example in meat, poultry, fish, egg, milk and dairy products.

Vitamin B12 is also used against growing grey and balding, but it also eases pain in the muscles.

It is important that alcohol and preservative additives hinder its effect, thus a body suffering from significant alcohol or preservative excess, is in demand of extra amount of vitamin B12.

If the level of B12 is too low in the body, anemia may set in, along with other deformities of blood producing organs and symptoms related to the dysfunctions of the nervous system (problems in the digestive system or fatigue).

Although vitamin B12 dissolves in water, it is an exception within this group since it can accumulate in the body. It has no harmful effect that we know of.
