Xylitol 101

Basics of Xylitol

Staying healthy through transformational hygiene. Xlear’s xylitol-based products support that goal.

Xylitol is a natural sweetener derived from natural sources. It is also produced in the human body as a by-product of a normal metabolism. Our xylitol is of the highest quality possible. It is a pharmaceutical grade, meaning it must be more than 99.95% pure, and is made from non-GMO (non-genetically modified organism) corn fibers. It does not contain any of the corn grain and it is tested to ensure that no corn allergens, mycotoxins, or corn proteins of any type are in the product.

Xylitol 101 is our dedicated page for introducing consumers to the Basics of Xylitol and the science behind using it in sinus care and oral care products. Choose a link below to find the resource you need.
