Mouth Sores in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted August 14, 2011 · Report to Admin Yes, I had mouth ulcers, too, as a symptom of vitamin deficiencies. But the sores got much less numerous and frequent after adding Bronson's Super B's along with the Therapeutic Formula of vitamins and minerals...and then, totally went away after we discovered the celiac disease -- except, of course, if/when I get accidently glutened. It is essential that we Celiacs take added vitamins and minerals to offset any nutritional deficiencies either because of malabsorption or because of a compromised diet. So, adding a Super B vitamin to you regime could be very helpful. It's nice to know that B vitamins are water soluble and so are not toxic in large amounts - in excess they just wash through your system. By the way, Bronson vitamin and minerals are sold in many USA medical schools. I buy them over the internet at: www.bronsonvitamins.com But, I am sure there are lots of other equally good companies out there. This particular company was recommended to me when I was a research subject for many years with the Clayton Foundation Nutritional Research Project at the U of TX, Austin. Unfortunately, the foundation has lost it's funding and are no longer operating. But, they were a fabulous help to me all those years when the medical community was ignorant about celiac disease. In fact, they are the ones who told me I was very vitamin deficient and also discovered the fructose intolerance.
