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).
Best sources of folate include long-grain rice, turkey and chicken giblets, legumes, asparagus, spinach, broccoli, brussel sprouts, lettuce and other dark leafy greens. The current RDA of folate is 400 mcg for adults.
