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).
The reason high folate levels are found in people who have a vitamin B12 deficiency is the body needs vitamin B12 to use folate, explains WebMD. When vitamin B12 levels are not within a normal range, the cells in the body cannot use folic acid, allowing it to build up in the bloodstream. However, a folic acid test is not the proper test to find a vitamin B12 deficiency. A low folate level can indicate diet issues, an eating disorder or alcohol dependency, according to WebMD.
