Hello. Thank you for posting your query at DoctorSpring.com
I understand your concern.
High Serum B12 levels can indicate some liver damage and can be elevated in conditions like cirrhosis, acute hepatitis ( e.t.c ). Apart from that some myeloproliferative disorders can also lead to high b12 levels. B12 can never be elevated because of overdose or toxicity. Since it is a water soluble vitamin, it normally gets excreted if taken more than required. Since you have no other symptoms, i won't be worried. However i will like to check your LFT, if not already done. If it is done and is normal, i will advise you to get a repeat B12 done after 7 days, and also external supplements for B12 is not required in your case. So you can stop the supplements you are taking, repeat it after 7 days and upload your reports. Also send us your CBC report.
Feel free to discuss further,
Regards

Thank you for your response. I had complete blood work at the same time which included Total chem panel, LFT, CBC with Diff, lipid panel, Vit D all of which were normal the only item that was elevated was the B12 ( Active B12 test ranges are more reliable) the test I had was total serum and I know it's not as reliable. So if I understand you correctly I should not be concerned and to stop all b12 supplements? I will recheck my b12 levels in a few months since all my other blood work is fine, correct? Have you ever ran across this before? Thank you for answering my questions and you have relieved my mind.
Hello. Thank you for writing to us again.
I am happy i could relieve your mind and answer your queries.
Yes for the time being i will advise you to stop all the b12 supplements gradually. Don't stop it immediately. Since you are taking 2-3 supplements cut down to one and then after 1-2 weeks you can stop it completely. You have been taking excess b12 and the body needs to slowly adjust back to getting normal b12 from the diet. Just follow a healthy diet and in my opinion, i want you to get a repeat serum B12 level checked after a month or a couple of months. It is no emergency. You can get it done as per your convenience.
As i said before since you have no other symptoms, there is absolutely nothing to worry. Just gradually cut down and then stop b 12 supplements within 2 weeks.
Hope this is helpful,
Regards

Thank you again I feel better I will take your advice and slowly decrease my vitamins... Have you experienced this before in your practice?
Hello. Thank you for writing to us again.
Yes occasional B12 levels have been high in certain patients, but in follow up they have come out to be normal. It is possible since you were taking so many supplements too. Please do not worry.
Once you get the repeat the test get back to us with your reports,
