I sell substitute sugar (NOT SWEETENER, it is made from sucralose and sucrose) which has zero GI and calories. It is heat and pH stable so it can be used for cooking, baking and beverage sweetening. There is absolutely NO after taste, because it is sugar, the only difference being, 1 teaspoon of sugar equals one fifth of a teaspoon of our product.
