Opposite of most but high b12?
 

I know I am the minority here but my b12 is very high and this is not a fluke. I had it tested multiple times. I used to take b complex about 1.5 years ago and it was then tested and my levels were 1500 so I stopped as my neuro said and it went to 2000. Now I have been off b complex and don't take b12 supplements for a year and half and my levels were tested this week and it came back 1473. No one seems concerned but I am wondering if this could be a sign of something or no. I have had so many tests for auto immune just went back for a repeat of another mri so on so am looking so to speak out of the box. I do have PN and RSD but for other possibles and why this is all happening. Any thoughts and thank you

The fact that it is coming down, means you are okay.

If it stayed up there, with no supplements, then you'd need to find out why. The most common cause for people NOT TAKING
supplements is a bacterial overgrowth in the bowel.

The other causes are very rare.

Thanks Mrs D. I just thought since it has been a 1.5 years it would of went down more. I do have bowel issues but that may not be what you mean. Side not and sorry for too much info but I have very bad constipation and tried everything anyhow they had suggested taking colace stool softner 2 times daily awhile ago. I am not big on these things but really need something anyhow I asked for how long and they were vague because of the severity of my constipation. How safe is this to take and for how long? Thanks again

Colace is pretty benign. I don't recall ever seeing negative
things about long term use.
