What is Aqua Plus actually? AQUA PLUS was specially developed for carbohydrate-free & calorie-free flavoring of water. Only ingredients of natural origin are used for this. The sweetness comes from the stevia plant! Just a few drops of Aqua Plus cherry are enough for a fruity, sweet and slightly sour cherry taste! This way, you get a heavenly cherry lemonade without any effort and above all WITHOUT SUGAR and without calories, which will give you a heavenly cool off during the hot summer days. Strictly speaking, cherries aren't really suitable for the ketogenic diet because they have too much fructose. With our Aqua Plus, you can treat yourself to the heavenly taste of cherries on a keto diet, but completely without the fructose and without the carbohydrates.
