About Vitamin B12 Deficiency Test in Berkeley
Vitamin B12, also called cobalamin, is a water-soluble vitamin that the human body cannot produce on its own. It must be obtained through diet or supplementation, and it depends on a complex sequence of digestive events to be absorbed properly.
Dietary B12 is bound to proteins in animal-derived foods such as meat, fish, eggs, and dairy. Stomach acid and the enzyme pepsin release the vitamin from these proteins, after which it binds to a protein called intrinsic factor produced by the stomach lining. This complex is then absorbed in the terminal portion of the small intestine, the ileum.
A deficiency can arise at any point in that chain. Inadequate intake is common among strict vegetarians and vegans, while malabsorption can result from conditions such as celiac disease, Crohn's disease, atrophic gastritis, or surgical removal of part of the stomach or ileum. Certain medications that suppress stomach acid or interfere with absorption can also reduce B12 levels over time.
Symptoms of low B12 are often gradual and nonspecific. They may include fatigue, weakness, tingling or numbness in the hands and feet, difficulty concentrating, and mood changes. Because the vitamin is essential for red blood cell development, a deficiency can also lead to a particular type of anemia in which red blood cells become enlarged and inefficient at carrying oxygen.
