with matters.”

    Awesome!

    Love these! I feel one tablet is enough, gets super foamy and it’s so minty! was very nice that they included some samples of the other flavors to try. Can confirm that they all taste minty (and not really like “sage” or “chai” etc) Excited to purchase more. Love that they’re in glass and made in the USA, on top of all the ingredients. Highly recommend!

    Great toothpaste

    Convenient and easy. Toothpaste option without the ick. Taste great and helps sensitivity. We find that half a tablet works well for us.
