Question 1

can you overdose on vitamin b12?

Accepted Answer

Virtually nontoxic: At any dose. I do not believe that you will find very much written on the toxic effects of B12 although I have had a couple of patients who took something on the order of 10x what I had prescribed them was already in the 10,000IU range so they were taking about 100,000IU daily for several weeks and the patient developed diarrhea.  When he stopped that resident, within several days diarrhea stopped

Question 8

what causes high vit b12?

Accepted Answer

Depends: Chronic myelogeneous leukemia, promyelocytic leukemia, polycythemia vera and also the hypereosinophilic syndrome can result in elevated levels of B12 mostly from increased production of haptocorrin. 
In addition, because the liver stores b12, liver diseases such as acute hepatitis, cirrhosis, hepatocellular carcinoma and metastatic liver disease can also cause a rise in serum b12.

B12 and Your Body: B12 is a water soluble vitamin that primary works in the formation of nerve tissue (myelin) and is essential for the maturation of red & white blood cells in the bone marrow (prevents pernicious anemia).  It is required in normal folate (folic acid) metabolims and dna synthesis.  Biochemically, one form of B12 (methyl b12) helps convert homocysteine to methionine for energy production &, brain &  heart health.

Question 10

Accepted Answer

No: If you have sufficient vitamin b12, extra doesn't help. Think of it like adding a fifth wheel to a car that needs four. Get your B12 from food such as wild salmon, sea kelp, and other sea vegetables. Don't let someone stick you with a needle if you can avoid it. Just a way to make money for some doctors and other health care providers.
