As a celiac myself (documented by genetic testing HLA-DQ 2 & 8), my prime objective every day is to be gluten free (GF)! I am so sensitive that any level of cross contamination causes me GI distress. TyH's stand is that we will not put gluten free on the label unless the product has been specifically tested for gluten. The government allows any product to claim GF status if tested GF (and it can still contain 20 ppm gluten!), no gluten ingredient has been added or is a food not considered to contain gluten (most dairy). Since our products are made and tested in a GMP-certfied lab, the odds of any product being cross contaminated is extremely low. The only product I do not take is Digesta-Care 8 as the trademarked ingredients from the enzyme company do not claim to be gluten free. I take all other TyH products with no GI issues. I hope this answers your question!
