    Crazy about this tablet toothpaste!

    I love the taste of these tablets, it is a very strong, minty flavor and makes my mouth feel fresh. My teeth feel smooth and clean after use. The best bonus is that there is no plastic tube to leave laying in our earth causing garbage.

    Puts me to sleep without the next morning grog

    I used melatonin for years and hated how groggy I felt the next morning. This toothpaste puts me to sleep without the grog.

    I have never been a fan of melatonin

    I have tried melatonin tablets in the past to improv sleep. Meh! They didn’t really seem to help and then I would feel groggy in the morning. I brush nightly with Sleep and I’m sleeping very well. I’m very happy with this product. I use Immunity in the morning and I am going to keep some of the Energy around for those low points that come along. I was so happy to have the samples they sent with my first order. I’m convinced this is a great way to brush teeth.
