Vitamin B12, also called cobalamin, is found in foods from animals, such as red meat, fish, poultry, milk, yogurt, and eggs. In recent years, fortified cereals, breads, and other grain products have also become important dietary sources of B12 and folate (identified as folic acid on nutritional labels).
This test measures the levels of vitamin B12 and folate in your blood. Your body needs vitamin B12, also called cobalamin, and folate, also called folic acid, to function normally. Both nutrients play important roles in creating red blood cells and making DNA and RNA to help build cells. B12 also helps your nervous system function as it should. B12 is found in fortified cereals and animal products like fish, meat, eggs, and dairy. It's also in dietary supplements, as cyanocobalamin. Folate is found naturally in green leafy vegetables, fruits, and beans, and it's added to enriched cereals and grains. People who have pernicious anemia may have low B12 levels because this condition prevents them from absorbing B12.
