"Erythritol is found naturally in some foods. It's also made when things like wine, beer, and cheese ferment.
Besides its natural form, erythritol has also been a man-made sweetener since 1990. You can find it with other sugar substitutes in stores and online.
It's also sold in bulk to companies that use it to sweeten or thicken products like reduced-calorie and sugar-free foods and drinks. You'll often find it mixed with popular sugar substitutes like aspartame, stevia, and Truvia to make them sweeter.Calories. Sugar has 4 calories per gram, but erythritol has zero. That's because your small intestine absorbs it quickly and gets it out of your body through urine within 24 hours. This means erythritol doesn't have a chance to ""metabolize"" -- turn into energy in your body."
