Vitamin B12 deficiency can be serious if untreated, because it can lead to decreased production of red blood cells in the blood. Healthy amounts of red blood cells are necessary for the proper delivery of necessary oxygen to the body's cells and tissues. A lack of sufficient amounts of red blood cells due to vitamin B12 deficiency results in a serious complication called vitamin B12 deficiency anemia or pernicious anemia.
Vitamin B12 is taken into the body by eating certain foods, including lean red meats, poultry, fish, and dairy products, such as milk, cheese and yogurt. In some cases, vitamin B12 deficiency can occur when a person does not eat enough foods that contain vitamin B12, such as someone who follows a vegan diet.
