High Levels of Vitamin B12 and Ferritin: Any pointers?

Hi @rubyjag3 As you can see you’re not alone in your concern over the very high Vitamin B-12 level in your blood tests and wondering what can be done. There is no indicated toxic level if someone is taking the vitamin in a supplement.
However, from my understanding, if there’s a significant excess of B-12 in the blood with no supplements it can be a sign of
low B-12 with what’s actually being used by the body. This can sometimes be caused by underlying conditions which interfere with how well it can be processed and absorbed. Anything in excess is waste and not being used, so it floats freely in the blood and is indicated by that high level.
There are some specific tests that can be done to see how well your body breaks down/absorbs and transport/bonds to Vitamin B-12.
Did any of this increase with your higher protein diet?
You said all of your other bloodwork came back normal. Did this include a kidney and liver panel?

Thank you for your response. It is true that I do not take any supplements or any medication at all. All my other blood work was "normal". However, I had an appointment last Friday and asked that it be checked again. I received the results over the weekend and my B12 has increased from 6066 on 8/5/22 to 7345 on 9/30/22. I have been feeling awful for about 3 weeks. Fatigue, dizziness, blurred vision late in the day, very dry eyes, headaches, confusion, and back pain (upper mid) I had an EKG on Friday as well to rule out a heart attack (all good). I don't know where to go from here.
You mentioned that there are specific test to see how well your body breaks down/absorbs B12, what are those test? My B12 was 1663 in March and is over 2000 now, (test doesn't say how much over 2000). Primary said its probably autoimmune related, autoimmune doctor says no. Yearly blood work came back normal for most part , Immature Grans, Absolute a little high and MCHC a little low. Not taking any supplements. Kind of at a loss.

Thank you......yes, (from 4000-6000 in the last 11 months) I have been focusing on increasing protein since January. How does that relate to the increase in B12?
