All three enzymes in Bright dental toothpaste have been extensively studied for decades and are well-understood. The lactoperoxidase system – the central active process of Bright dental toothpaste – is well-documented in many different mammals (including humans!).
Novozymes has used the same three enzymes in Bright dental to make a popular human toothpaste, Zendium. Kind of like Nutella a few years ago, it's hard to find in America, but it's crazy-popular in Europe. One of our founders (Henrik) grew up using it!
There is extensive research in humans that supports the effectiveness of these enzymes as part of a healthy oral hygiene routine.
