Hello everyone! I'm new here, so I hope I'm posting this in the correct place... =P And I just want to say that this board is such a great place of information! I have been recently diagnosed with vitamin D and vitamin B12 deficiency. My doctor tells me that since these are rare to have a deficiency in, especially in my age group (I'm 19) he thinks that I may have some type of gluten intolerance, which is causing the vitamins to not be absorbed. So I am now supposed to be living gluten-free, which is why I'm here now! I haven't noticed any stomach issues on my current diet, so there is no way of me knowing if I've really eaten any gluten by accident. I am currently taking prescribed vitamins, and I am (trying) to stay on a gluten-free diet, but how will I know whether the gluten is affecting me or not? And does gluten usually affect the absorption of vitamins?
