    Great choice for switching from plastic and harmful ingredients

    I switched to Duo because I wanted a clean, non plastic encased toothpaste. I am very pleased with it and knew I made a great choice when my dentist commented on how clean my teeth are!

    Awesome tablets

    So far I have tried the Immunity, sleep and energy Duo tablets. I love how they foam up with brushing. I was skeptical to try these because of the flavor but have been pleasantly surprised by all. I really like the mint and sage. I have been using one of the other toothpaste tablets for over a year now and I liked those but am much happier with these. They are a little spendy but I do appreciate knowing what I am putting in my body.
