As one of the first energy drinks with zero sugar, under 10 calories and 15+ flavor/formula variations, XS Energy Drink is a truly innovative product in the beverage market. Launching in early 2001, XS quickly became one of the top manufactured energy drinks in the United States, and has since expanded into no less than five additional markets worldwide. XS Energy Drink was also the first to capture the family market with by-the-case sales, leveraging online & direct sales channels, rather than single can distribution through traditional retail outlets.
