Congratulations, you discovered the best keto friendly sweetener on the market. KetoseSweet+ liquid contains allulose — a rare natural sugar found in maple syrup, figs, and raisins — and is a safe, non-caloric, non-glycemic sweetener. Allulose is not metabolized and is nearly calorie-free. The FDA requires allulose to be listed in the sugars section on the nutrition facts panel.
