What is Xylitol?

Xylitol is a naturally occurring carbohydrate. It is found in fibrous vegetables and fruit. It also occurs naturally in our bodies – in fact, an average size adult manufactures up to 15 grams of xylitol daily during normal metabolism.

Where Xylitol Comes From

Xylitol is found widely in nature. In addition to a variety of fruits and vegetables, Xylitol is also commonly extracted from birch bark.
