Pure, Granulated Xylitol No Added Ingredients The Perfect Substitute for Sugar 1/3 Fewer Calories Than Sugar Perfect for Ketogenic and No-Sugars Diets Low Glycemic Impact NOW Real Food® Xylitol is the incredible pure sweetener that more and more people are turning to as an ideal substitute for sugar. Unlike sugars such as sucrose and fructose, this sugar alcohol won’t promote tooth decay, has a low glycemic impact and has around one-third less calories than other sugars, making it a low-calorie, diabetic-friendly and keto diet-friendly sweetener that’s hard to beat. Why we prefer corn-based Xylitol Our xylitol is proudly produced from non-GMO corn cobs which would otherwise go to waste. We believe corn-sourced xylitol is more sustainable than other sources such as birch trees which involves stripping the bark and eventually killing the tree.
