High serum B12 dangerous?

[Ctadds1]

My levels are now above the measurable limit of 2000. I have been receiving injections for 6 months. I’ve read some things that say high levels can cause other serious health concerns like cancer, liver disease, etc.

Do I need to be concerned?

So is it that often times people with certain types of cancer/liver disease/etc then have high B12 because of those disease OR high B12 can be the cause of those diseases?

Ugh, confused ....

Your B12 blood serum is high because of injections . Do not worry about it . My B12 blood serum is off the measurable scale also . I’ve been injecting weekly for 5 years . You cannot overdose on B12 luckily ( the same cannot be said for all vitamins ) Read the pinned posts on the right hand side relating to this subject . Put your mind at rest . Best wishes .

I think if youve a pre existing undiagnosed cancer cells. The b12 can make your body multiply them as everything 'wakes uo' simply put but my understanding of all that I read.

Hopefully' that ship has sailed '

I looked into this as a neurologist really scared me about 'over dosing on b12 and cancer risks .

I was on every other day at that stage and had been for 3 months.

That was over 2 years ago .

I continue to inject every 6 days.

High levels of B12 can be caused by certain cancers and liver disease.

There is no known health risk in having high levels of B12 from injections. stichtingb12tekort.nl/engli...
