Vitamin B12 comes from animal products such as meat and eggs, and is absorbed through a special protein called Castle’s intrinsic factor. The latter is absent in people suffering from pernicious anemia. Since in this case, the body does not absorb vitamin B12 and its reserves are depleted, over time, the characteristic symptoms of the disease appear.
Signs of vitamin B12 deficiency on the tongue
As noted by experts from National Institute of Health (NIH), an early clinical sign of B12 deficiency may be the “linear” lesions on the tongue. The condition is manifested by the stretching and disappearance of the taste buds, due to which the tongue becomes soft, sensitive and can hurt. In medicine, it is known as glossitis.

How to replenish vitamin B12
One of the best sources of vitamin B12 is organ meat, more specifically liver and kidneys. A 100 gram serving of lamb liver contains a whopping 1,500% of the recommended daily intake of vitamin B12.
The fish like sardines, tuna, trout and salmon are excellent sources of vitamin B12. These fish not only provide vitamin B12, but are also rich in many other micro and macronutrients.
Other aquatic animals like clams are also a good source of the vitamin. A single small clam can provide 165% of the recommended daily intake of vitamin B12. Another great source of vitamin B12 that is easily accessible to non-vegetarians is eggs. Consuming just two whole eggs provides the body with 22% of the RDI for vitamin B12, along with many other nutrients.
