 Most products containing sucralose add fillers and additional sweetener to bring the product to the approximate volume and texture of an equivalent amount of sugar.Though sucralose contains no calories, products that contain fillers, such as maltodextrin and/or dextrose, add about 2–4 calories per teaspoon or individual packet, depending on the product, the fillers used, brand, and the intended use of the product.The US Food and Drug Administration (FDA) allows for any product containing fewer than five calories per serving to be labeled as "zero calories".
