How does XS™ taste so good without sugar, carbs and so few calories?

XS Energy Drinks use a proprietary blend of Sucralose, Acesulfame Potassium (Ace K) and fruit flavours to give the drinks their great flavour without sugar or empty calories. In fact the 8 calories in the drink come from the 2 grams of amino acids, which are protein calories. THE SWEETENERS Acesulfame Potassium-Ace-K is non-caloric, non-cariogenic (does not promote tooth decay), non-nutritive sweetener that delivers powerful, great-tasting sweetness (approximately 200 times as sweet as sucrose). Preferred because its sweet taste is perceived quickly, does not linger, and does not persist longer than the taste of the product. It provides excellent sugar-like taste.

Sucralose is a revolutionary no calorie sweetener that is made from sugar, so it tastes like sugar. It has an outstanding safety profile. Sucralose has now been approved by the regulatory agencies of more than 50 countries, including the United States (1998), Canada (1991), Australia and New Zealand. Today, millions of people around the world enjoy more than 400 foods and beverages sweetened with sucralose.
