Whether you’re reducing sugar due to diabetes or simply aiming for a healthier lifestyle, you can still enjoy tasty Ninja SLUSHi treats that are low in sugar—or even completely sugar-free! All it takes is the right ingredients.
Though the manual suggests adding sugar or alcohol to all slushies, members of our Ninja SLUSHi Facebook group have successfully used 1/2 tablespoon of allulose syrup for every 8 ounces of liquid to achieve the perfect slushie consistency without the sugar.
Others have had success using monk fruit sweetener blended with erythritol, which provides sweetness without spiking blood sugar—though you may need to experiment a little to find the best ratio for freezing.
Here is our recommended Monk Fruit sweetener that will help you craft delicious, sugar-free slushies:

Why Do Slushie Machines Need Sugar, Alcohol, or Allulose?
Slushie machines require sugar, monk fruit, allulose, or alcohol to function correctly because these ingredients lower the freezing point of the liquid. This ensures that your slushie mixture reaches the ideal slushy consistency without turning into a solid block of ice. Essentially, sugar, monk fruit, allulose, and alcohol prevent the liquid from freezing at normal temperatures, and the exact freezing point will depend on the sugar concentration or alcohol type.
Enjoy experimenting with these substitutes to create your perfect sugarless or low-sugar Ninja SLUSHi!
