Query: It does what it claims

It does whiten and does improve your breath after using. My only problem is the taste. It's overpowering. Prior to this I used Colgate Total 24hr Healthy Mouth plus whitening toothpaste (which tastes much better and also works well but isn't all natural). They should make a less minty flavor for those of us who prefer good tasting toothpastes! I also tried Jason NutriSmile Toothpaste, Orange/Cinnamon/Mint and it tastes much better but doesn't freshen breath aswell or whiten as good.
