This luscious lime-flavored Margarita Mix is the unbelievable beverage that started it all! Bob's Original sugar free formula means you can enjoy a refreshing Margarita without worrying about calories and carbs! Let Bob break it down for you: ZERO calories per serving! * That's right, ZERO! The average sugar-loaded margarita mix can run over 250 calories per serving! ZERO sugar and ZERO carbs! Bob's secret formula is sweetened with Splenda. It tastes like sugar, because it's made from sugar! Other sugar free mixes are made with erythritol or aspartame, which have an aftertaste and can have a laxative effect. Bob isn't a fan.
