    Love it!

    I like the taste, the tabs' crunchiness and the clean feeling afterwards. The tabs produce a nice foam to help with the brushing.

    Fall asleep faster

    I love using the immunity in the morning and the lavender mint(sleep) at night. I had my son try it out he loves the sleep one bc it helps you fall asleep gently. These tablets leave my teeth feeling cleaner, stronger, and with reduced sensitivity.

    Best option we've found!

    I've been purchasing and trying various toothpastes and tooth tablets for the last six months in an effort to find one for my family. My criteria was that it needed to contain nano hydroxyapatite, taste good to my children, and fit in our budget. I've tried four different brands so far and Duo has come out on top. They weren't the cheapest, but my kids wouldn't use the others. They tasted horrible or foamed so much they were rejected! I was also gratified to see the different options of sleep, energy, and immunity. I've tried all so far and have stopped my search.

    I would love to see Duo branch out to other flavors, but the mint flavors are working for us so we won't switch.
