Yes it is. Xylitol is not a drug, nor is it habit forming. In 1983 the JECFA, a joint, expert committee of WHO (World Health Organization) and FAO, confirmed that Xylitol is a safe sweetener for foods. It is approved for use in Australia by the FSANZ (Food Standards Australia New Zealand), and Xylitol has been the subject of over 1500 research studies.
