Imported from China, this Red Bull Zero Sugar energy drink is infused with a tropical burst of passion fruit. Ideal for getting through a busy day or challenging workout, the formula of quality ingredients contains around the same amount of caffeine as a cup of homemade coffee. Water-soluble b-vitamins, taurine – the bodys natural performance-improving amino acid – and non-caloric sweeteners are also part of the popular mind-and-body drink recipe.
