Fortified cereals

Because it's synthetic and not sourced from animal sources, this vitamin B12 source, fortified cereals, may be suitable for vegetarians and vegans. Although fortified cereals are not typically advised as part of a balanced diet, they can be a useful source of B vitamins, particularly B12. The process of adding nutrients to food that were not originally there is known as a fortification. For example, 1 cup of Malt-O-Meal Raisin Bran has up to 62% of the daily value for vitamin B12 (59 grams). This cereal also contains 29% of the daily value for vitamin B6 and significant quantities of vitamin A, folate, and iron in the same serving.

According to studies, eating fortified cereals on a daily basis can help boost vitamin B12 concentrations. In fact, one research found that participants' B12 levels increased considerably after eating 1 cup (240 mL) of fortified cereal with 4.8 mcg (200% of the DV) of vitamin B12 daily for 14 weeks. If you decide to supplement your vitamin B12 consumption with fortified cereal, look for one that is low in added sugar and high in fiber or whole grains.
