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).
Dietary sources include citrus fruits and juices, tomatoes, broccoli, and cauliflower. Vitamin C supplements may interact with other medications, including chemotherapy drugs, estrogen, warfarin (Coumadin), and others. Vitamin B12 helps in cases of vitamin deficient or pernicious anemia. Dietary sources include liver, meats, eggs, tuna, and cheese. People with pernicious anemia cannot absorb the proper amount of vitamin B12 and may need lifelong supplements. Folic acid can be taken for folic acid deficiency, which can cause anemia. Good food sources include green leafy vegetables, orange juice, and grains. Taking a folic acid supplement can hide a vitamin B12 deficiency, so always take vitamin B12 when taking folic acid.
