Fortified grains and cereals
Whole grains and breakfast cereals fortified with vitamin B12 and other essential vitamins are an excellent way to compensate for vitamin B12 deficiency. A single serving (28 grams) of oat breakfast cereal contains 105 calories and nearly 54% of the daily value for vitamin B12. Cereal is a fortified diet that is an excellent choice for vegetarians. To obtain the greatest health benefits, it is essential to choose a breakfast cereal and grain that are high in protein and fiber.
