Erythritol is a sugar alcohol (polyol) used as a sweetener in many reduced calorie foods. The erythritol in our products is obtained through the fermentation of glucose from non-GMO corn using yeast. It is similar to the erythritol that occurs naturally in fruits like pears, melons and grapes. Erythritol’s caloric value of zero calories per gram, low glycemic index, crystalline appearance, and high digestive tolerance distinguish it from some other sugar alcohols.
