LadyPN posted a topic in Gluten-Free Foods, Products, Shopping & MedicationsI am new here. I have a Peripheral Neuropathy. I was tested for IGg/IGa Gliadin Antibodies and Transglutaminase. However, the laboratory substituted the test to "deaminated" Gliadin. My doctor said that it should not have been substituted with "deaminated" because I have neurological symptoms. The doctor explained to me that sometimes, some can be negative but still be gluten intolerant. The best thing to do,he advised, is to experiment gluten free diet. This is where I am now - strictly following gluten free diet. I am taking calcium . I inquired from the Customer Representative of the product and I was told that they are not using any ingredients with gluten, however, they buy their ingredients from different sources. Therefore, they could not guarantee that their ingredients are free from contamination either in the facility of their suppliers or during transport. I need to take calcium supplement. Please advise me if I can post the brand, so the answer to my question can be more specific. Thank you.
