A member asked:

What are your thoughts on a high b12? should the cause be investigated with symptoms such as spontaneous bruising, muscle atrophy, parathesias

Dr. Randy Baker answered

Specializes in Holistic Medicine

Needs evaluation: B12 is not toxic so high B12 due to taking it is not bad. If someone has high B12 without taking it then it can be a sign of serious problems including liver & kidney disease, myelproliferative disorders including leukemia & polycythemia vera & hypereosinophilic syndrome. High B12 does not cause these but caused by them. Further tests are needed to find the underlying cause: http://bit.ly/1hVpCY7
