Not all of the smoothies are gluten free, but the vast majority are, and apparently they have two different types of blenders, and one of the types only handles smoothies that are gf, so ask about that! Otherwise the smoothies are made with mostly minimally processed ingredients- frozen fruit, various milks, seeds, so it seemed quite safe. The employee there at the time was happy to answer my questions and the smoothie was delicious.
