Elevated vitamin b12 levels


BuddhaBar

Went to the GP to get some blood work done just to check how I was doing. Turned out I was doing great with no deficiencies.
But, my b12 levels was elevated. It was 986 and maximum normal level according to the test should be 650.

I'm not supplementing on b12 anymore. In fact I stopped taking the pills over a month ago. I've googled and found out that elevated b12 levels can be a sign of leukemia, liver or kidney disease. However, my liver tests were normal. My white blood cell count was also normal. And I looked up the symptoms of kidney disease, but I don't have any of those. Creatinin was normal. GFR was 93. Read that a value of 90 and above indicates that the kidneys are working properly. 

Is there anything else that can be causing these elevated b12 levels?

Give it a year after ceasing supplementation.  Mine was over 2,000 when I was diagnosed 6 years ago.  I did not supplement intentionally.  I was drinking fortified soy milk because I was lactose intolerant at the time.  I was not taking a vitamin b-12 supplement. 

My last few tests were 872 and 881 and were just within  my lab range of 900 (the max).  Every lab has different ranges.  I take no supplements or fortified food.  Just real food that my body can use and not synthetics.

Thank you for your reply. I guess b12 is stored somewhere in the body (liver maybe?) and that's why the levels are still high. I suspect I didn't need those supplements in the first place. I just assumed I was deficient and overdosing on b12 is not possible so I just kept taking those pills and wasted money on them.
I will give it some time and maybe stop overeating fish and eggs. When I had magnesium deficiency I ate over 500 grams of mackerel per day. That's a lot of fish. Anyway, I hope it's nothing going on in my intestines that's causing this.

I eat eggs every single day.  Real food.  My theory is that I was unable to process the synthetic version that was added to soy milk.  Adding it to soy milk makes sense since often vegans do not get B-12 in their diet.  Now I can eat dairy with ease!  

Your body stores 3 to 5 years worth of B-12 in your liver.  No need to supplement unless you have a deficiency.  Glad your doctor checked.  If you were vegan, you would probably need to supplement.  

I have healed from celiac disease, but the first treatable symptom of Autoimmune Gastritis is a B-12 or iron deficiency.  My internist keeps an eye on those.  So far, so good.

Hi there did you have any strange side effects with all the B12? My levels were also 2000 but I've been taking supplements too in addition to all the food and my body just  doesnt feel right.

Welcome to the forum. This thread is older so you may not get a reply from the original posters, but it’s my understanding that such high levels should not hurt you, although my doctor asked me to cut back on my B12 supplementation when my levels hit 1,500.

Thanks Scott, I was concerned due to what I was

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.

      You state in an earlier post that you don't have celiac disease. Here in this post you state you will "be doing another test". What will this test be looking for? What kind of celiac disease testing have you had done? If you have used a Entero Labs it sounds like you have had stool testing done for celiac disease which is not widely accepted as a valid celiac disease diagnostic testing method. Have you had blood antibody testing for celiac disease done and do you realize that for antibody testing to be valid you must have been eating generous amounts of gluten for a period of weeks/months?

      No, I've not been diagnosed as celiac.  Despite Entero Labs being relocated to Switzerland/Greece, I'll be doing another test. After eating wheat products in Greece for 4 weeks, there wasn't any reaction.  However, avoiding it here in the states.   Thanks everyone for your responses.
