Is GoodBar gluten-free?

In fact some GoodBar flavors do not contain flour, oats, or other glutinous products (ex. Coffee Hazelnut). The reason these are not certified Gluten-Free is twofold: 1) The origin of the ingredients and raw materials must be certified gluten-free and some of our suppliers can not claim this. 2) The production environment must be completely free of gluten.
