In adults, blood cells are produced by red bone marrow, which is located inside the centre of the hips, ribs, breastbone and backbone, in addition the ends of long bones such as the thigh. Red blood cells live for around 120 days before they are broken down and replaced, as part of a normal renewal process.

Vitamin B12 is a important product in DNA, the chemical that carries genetic information for new cells. It's located in meat and animal products but not in vegetables. You need vitamin B12 to produce red blood cells and for maintaining healthy nerves.

What are the causes of Vitamin B12 deficiency?

There are numerous different causes of anemia. A deficiency of vitamin B12 in your diet is just one possible cause. Other nutrients that you need to produce red blood cells include iron and folate (folic acid). A lack of these in the diet can also cause anemia.

Most people who develop vitamin B12-deficiency anemia can't make enough of a substance referred to as intrinsic factor in their stomach. This intrinsic factor is needed for vitamin B12 to be absorbed from food and drink. This is a condition referred to as pernicious anemia. Pernicious anemia is an autoimmune ailment. Normally, antibodies manufactured by the body's immune system attack strange substances such as viruses and bacteria. With autoimmune conditions, the immune system mistakes the person's own tissue as strange and fights it instead.

With pernicious anemia, antibodies fight the cells in the stomach that make intrinsic factor. The exact cause of pernicious anemia isn't known. Its most common in people aged over 60. It affects women more than men, and is more popular in people with blue eyes, early graying hair and blood group A.
