    My internist has no explanation for the high B12 level and does not seem concerned.I am.Do you have an explanation?

I researched high B12 blood levels as mine is very high
There is no established UL for B12 as it has a very low potential for toxicity-IOM states -no-adverse side effects have been associated from food or supplements, in healthy individuals & recommends adults over 50 get B12 from supplements or fortified food as there is a high incidence of impaired absorption in this age group of B12 from foods that come from animals.

I can't help but wonder if the blood level is high as it is not being used by the body.
I have been taking Salmon oil capsules to get the Omega oils & my practitioner has suggested that I reduce these capsules from 2 to 2 per day & I will have blood re- checked.

have recently found that low magnesium levels can be the cause of leg cramps as the ratio of it to calcim should be higher than it is in many Supps.& low magnesium can also contribute to osteoporosis. Ther is a lot of info out there. Do not have source of my research but can look it up later Will be away for a week

Just wandering if 950 was high for b 12, of course I looked on internet and freaked myself out.  Trying not to obsess about it until Wednesday when I see doctor.  I have hypothyroid and it is high right now too, 7, and may have Celiacs, not sure but I see how gluten affects me.  I have every symptom of b12 defficiancy so that is confusing.  Tingling and etc.  I thought for sure I would show a lack of B 12, I am taking a supplement, just over 100mg a day, plus i get plenty in my food and I do eat seaweed occassionaly.  Anyway any insight?

Interesting!  I have high B12 levels, low iron, and am constantly tired.  My sister and mom were both diagnosed with hypothyroid but my hypothyroid tests have turned up negative.  I feel like I have all the symptoms for b12 deficiency too and yet my levels are so high.  It's weird that these sort of symptoms go with high b12 levels!

I was diagnosed with b12 anemia a year ago and my level was 210. They started me on shots once a week for a month and it was 410 and I was feeling much better.  Then my insurance dropped so I started taking the b12 pills, after I started taking them I started to get symptoms of b12 anemia back. I recently got insurance again and had bloodwork done. My bloodwork came back normal but my b12 was high above 2,000! I was always told that having a high b12 was not bad for you because any of it that your body doesnt use is passed through your urine. I am just confused as to why I also feel so tired all the time like I am still anemic. Does anyone knw if having high levels has the same symptoms as low levels?
