A member asked:
Just received my blood tests back and it states that my b12 is >1500....what could be the cause and what could happen to me because of this?
A doctor has provided 1 answer
Taking B12 or...: High B12 is harmless as it's not toxic; the most common cause is taking B12 & since you're taking it that's probably why it's high.. However, high B12 in someone who isn't taking it can be a sign of serious problems like liver or kidney disease or myelproliferative disorders. High B12 does not cause these but caused by them.
