| Re: B12 level High
Hi cvoor,
5000 mcg daily is extreme, in my opinion. Evidently, your doctor thinks there's no harm in doing so. I once asked a pharmacist if there would be any harm in taking a large dose of B12 and she said "yes". She said that too much B12 can put other B vitamins out of balance. And she referred to a study that was published in a journal, I think it was AMA (not sure).
It seems that many doctors, including the one I had, think that if you get too much there's no harm because you will just pee-out the excess. That may be partly true but, in the process, you may lose other B vitamins that you can't afford to lose. And, in your case, it seems your body didn't get rid of enough of the excess B12.
