Soda-Club / SodaStream regular syrup flavors contain sugar (sucrose), not high fructose corn syrup (HFCS). While many of our labels do say “sugar and/or high fructose corn syrup”, we have chosen to formulate without high fructose corn syrup and have not yet updated our labels to reflect this fact. The exception to this is Energy Drink, which indeed does contain fructose and dextrose, in addition to sucrose. In addition to sugar (sucrose), regular syrup flavors contain sucralose (Splenda® brand) and some also contain acesulfame potassium. If you have dietary concerns, please read the label of every Soda-Club / SodaStream product before purchasing, available by clicking the syrup images on the Flavors Galore page of this website. When in doubt, consult with your physician.
