Ear-a-Saurus dietary supplement contains Xylitol, which has been the subject of research indicating it provides nutritive support for normal levels of bacteria in the ear. When bacteria enters the body, it holds on to tissue through a variety of sugar complexes. Xylitol has been studied for its ability to interfere with this adherence. In studies, Xylitol has also been suggested to help support oral health by inhibiting the micro organisms most responsible for tooth decay, S. mutans. For maximum absorption, chew tablet slowly.
