    Love all the combinations from duo

    I started buying toothpaste tablets because I wanted to do away with the plastic tubes that all the major brands use and tried several brands before I discovered Duo and I will never go back to another brand. I love all of the different combinations and use them daily. I use the sleep at night before I go to bed, the Energy in the morning when I first get out of bed, and the Immunity during the day after a meal.

    Nice change

    I like the convenience and cleanliness of using this to clean my teeth. It also feels refreshing and like my teeth are benefiting more than using my usual toothpaste.
