Interesting, usually people have low B12. You say you’re on supplements- did the doc suggest that previously? Was it low before? Sorry I don’t have any insight. I’m curious what others have to say, though. 

No doc ever prescribed supplements - they have never shown an interest in vitamins/supplementation.    However, my PCP just recommended I increase my Vit. D to 5000 IU/day.  He didn't think the elevated B12 would be a problem, since apparently the body gets rid of excess B12, which I don't understand - if my blood levels show a high level, apparently I'm not getting rid of the excess?   I feel a little uneasy about the elevated B12, and am hoping it's just an anomaly for some of us who are missing their colons (and a couple feet of small intestines), but honestly - it doesn't make sense to me.    Thanks for responding, Bubba1028.
