Casein Phosphopeptides (CPP) are a natural derivative of milk protein. CPP helps to cluster ACP molecules into a stable and usable form critical to their use in tooth and bone treatment. The resultant CPP-ACP combination binds effectively to teeth and bones, but as an added benefit, binds twice as effectively to plaques and bacteria. This is particularly useful for dental applications as it provides the harmful agents an alternative calcium rich source to bind to protecting the teeth and soft tissues. In clinical studies, demineralization was reduced by 25-50% with two daily applications of CPP-ACP.
