    Love it

    I love these toothpaste tablets! Perfect for travel and keeping your life low-waste. These have a ton of lather and are easy to crush unlike the toothpaste tablets from Lush.

    A Pleasure to Use Plus Immunity Too!

    I was a longtime Bite Bits customer but the Duos are so much more pleasant to use (softer and frothier) and I love the immunity feature. In fact, after frothing, I make a point of keeping them in my mouth for a bit before brushing (while I'm applying makeup, for instance) to increase the absorption. Very pleasant way to start and end my day!

    Routine

    I love using the immunity tablets. It has helped keep my son and myself healthy even during flu season. We also enjoy using the sleep tablets. It gently rocks me to sleep within a decent amount of time. So give them a try it's definitely worth the investment.

    I love how foamy it gets and fresh it feels. Also you cannot beat the convenience and how much neater it is to use, store and travel with.
