"Quest is the first bar you can eat guilt FREE! To bring you a bar this healthy and tasty, we had to create a whole new process for making bars. Quest is so revolutionary, in fact, that we've filed a patent! That's why you won't see any other bar like it on the market. Quest is the first truly low carb bar that doesn't contain glycerin, simple carbs, sugars or artificial sweeteners. Quest Bars are the ONLY bars that you can eat without feeling guilty!" Gluten-Free.
