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 vital product in DNA, the chemical that carries genetic information for young cells. It’s located in meat and animal products but not in vegetables. You need B12 to produce red blood cells and for maintaining healthy nerves.

Most people who contract 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 known as pernicious anemia. Pernicious anemia is an autoimmune condition. Normally, antibodies manufactured by the body’s immune system fight foreign substances such as viruses and bacteria. With autoimmune conditions, the immune system mistakes the person’s own tissue as foreign and fights it instead.

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