It depends on the brand. I opt for ChocZero, which has the best sugar-free chocolate for diabetics and those who follow a keto, low-carb or sugar-free lifestyle. ChocZero sweetens their products with monkfruit, which causes little to no digestive upset. Lily's also offers great sugar-free baking chips with amazing flavors like Chocolate Salted Caramel Baking Chips that are sweetened with both erythritol and stevia.
