Sweet and Low is not made of regular sugar, but rather consists primarily of saccharin combined with dextrose and cream of tartar as bulking agents. Dextrose is a simple sugar used to dilute the intense sweetness of saccharin so consumers can measure it easily in packet form. Each pink packet contains very few calories and provides zero actual table sugar, making it suitable for people monitoring their sugar intake. It is widely used in coffee and tea as a sugar substitute.
