In the case of vitamin B12 deficiency, the symptoms can be subtle or even non-existent. Diarrhea, constipation, fatigue, loss of appetite and pale skin are some of the symptoms associated with this condition.

Most people can prevent this type of anemia by including animal products into their diet, such as milk, cheese and eggs. However, anemia is often treated with B12 supplements in the form of tablets or injection.

A supplement is necessary if a person doesn’t have any intrinsic factor (glycoprotein that helps the transport of vitamin B12 to the stomach so that it can be absorbed by the intestine). Supplementation is also advisable for elderly people or those who have problems with absorption or intestinal inflammation.
