I tend to get a lot of sore taste buds on my tongue (I hope most of you know what I mean). I did not have this problem, except for the occasional sore taste bud, before going on a vegan diet 7 months ago. I'm pretty careful in making sure I get all the vitamins I need, but I have IBD and so that diease can cause some people to not properly absorb all their vitamins or certain ones. Has anyone heard of sore taste buds on the tongue being a vitamin problem or something else?
