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).
Vitamin B12, also known as methylcobalamin or cyanocobalamin, is an indispensable nutrient commonly found in a variety of non-plant based foods, such as fish, shellfish, meat, eggs, and dairy products.Because animal products provide optimum food sources for vitamin B12, vegans have the greatest risk for deficiency.Vegetarians who eat eggs and milk products are also at risk because, on average, they consume less than half of the adult Recommended Dietary Allowance (RDA) of vitamin B12.race amounts of vitamin B12 can be found within tempeh, seaweeds and organic plants in specific geographic regions. ** But unless and until these foods are shown consistently to correct vitamin B12 deficiency, vegans should not rely on them as a vitamin B12 source.
