Vitamin B-12 is an important vitamin for many bodily functions, such as brain health, blood cell production, and proper nerve functioning. People who are obese or eat a lot of meat also tend to have higher-than-normal levels. High levels of vitamin B-12 can be a sign of liver disease, certain types of leukemia, or diabetes.
