Sugar Reimagined uses Allulose, which is clinically and scientifically proven to have zero net carbohydrate impact; this is why the Allulose carbohydrates are subtracted from the Total Carbs to produce zero net carbohydrates.  Allulose is a sugar that does not affect your blood sugar or insulin levels.
For all products, the Net Carb Calculation is Total Carbs less Allulose Carbs = Zero Net Carbs.
