Dr. Smoothie Watermelon Kiwi Refresher Concentrate is one of the very popular Refresher flavours at Cupper’s. Dr. Smoothie Refreshers are made from fruit juice, pure cane sugar and Stevia. They are lightly caffeinated with green coffee bean extract. (Click here for more info on green coffee bean extract). All the amazing fresh fruit flavours you want and with a natural boost of energy is found in each Refresher concentrate. They can be blended with regular still water, or use sparkling water for a bright, (dare we say) refreshing, thirst-smashing drink. There’s no artificial flavours or preservatives. And finally, they’re vegan, fat-free, and gluten-free. Each bottle holds 46 ounces of concentrate which makes fifteen 12 ounce drinks, each with 24 mg of caffeine. It just doesn’t get much better… or taste more refreshing!
