What it is

Xylitol is a sugar alcohol that occurs naturally in many fruits and vegetables. It is commercially produced from xylose, a sugar derived from plant materials like corn cobs or birch wood. The process typically involves hydrogenation of xylose.

Why it's used

Xylitol is used as a sugar substitute in a variety of food products, particularly those marketed as sugar-free or reduced-sugar. It provides sweetness with fewer calories than sugar and does not contribute to tooth decay. It is often found in chewing gum, candies, baked goods, and toothpaste.

Health notes

Xylitol is Generally Recognized As Safe (GRAS) by the FDA for use as a sweetener. It is not metabolized by bacteria in the mouth, which helps prevent cavities. Consuming large amounts of xylitol can have a laxative effect for some individuals. JECFA and EFSA have evaluated xylitol and established acceptable daily intakes.

Allergen info

Xylitol is not derived from any of the nine FDA major allergens. It is also gluten-free.
