Most people don't realize that the "zero calorie" name brand version of sucralose uses bulking agents, specifically dextrose to give it that heft. Dextrose is just another form of sugar. They are able to market it as "zero calorie" because it is under 5 calories per serving. This however is the exact same zero calorie sweetener w/NO bulking agents and therefore NO calories.All the same sweeteness, you can still bake w/it and most importantly this is significantly sheaper compared to the amount of sweetening you can get from the brand name stuff. It's just pure liquid sucralose.If you want to be more precise in how you dole it out you can buy a glass bottle w/dropper and fill it from this as I do. A 2 oz. bottle lasts me months. This purchase lasts years.
