Different Sort of B-12 Problem

mine are high too but its because im not assimilating b12 at all and its circulating in my blood rather than being absorbed in my small intestine. i actually have to get b12 shots next week..

i actually had been eating a lot of veal liver lol. i guess it was a no go :P

by high levels of B12 in blood + High RDW result. in canada, normal levels are 133.00 pmol/l and mine is 177. its not severe yet but my GI dr wants a few injections just to boost and retest to see whats going on. not sure what the long term management is yet though....

The more I think about it, this sounds like my issue. I will stop them a couple of days before the retest. Is that enough time to get rid of any extra caused by the sublingual tabs?

lady1012, really? my first shot is next week!

Chris B.: vitamin b family are all water soluble, so if you stop, you'll pee it out so it shouldnt be a problem. but its not because you're taking to much.. its just the b12 not binding to transcobalamin II to transport it correctly. however, a naturopath friend of mine recommended another type of sublingual b12 for me to check out. forget the name but its methylated and apparently is assimilated right away.. not sure of exact details but i'll post it on friday just to see the difference between the two.

Retested today. Somewhat concerned as I skipped supplement both yesterday and today prior to taking test today. Reading was 1424. I usually trend around 400-600. The concern is that this could indicate an underlying condition. Am I being paranoid?

Sounds like the way you are taking your B12 may be the issue. Maybe talk to your doc about trying the monthly B12 shot.

To lady, I am so surprised you feel bad the next day. I feel so much better the day after my shot. I find I sleep better and have more energy.

B12 is one of those supplements that its hard to overdose on. Becuz what your body does not absorb, it usually is peed out. Hugs!

Dagger - to answer your question, the terminal ileum is the only part of the bowel that absorbs vitamin B12, and this is the most commonly affected area of the bowel for CD, which means if the bowel in this area is all diseased and ulcerated it is not very good at absorbing the vitamin regardless if what foods you eat that may be high in B12. Alternatively someone like me who has had a bowel resection and has had that area of the bowel completely removed, can't really absorb much B12 from food at all, so has to get B12 injections every few months.
