Quest is the first bar you can eat guilt free

To bring you a bar this healthy and this 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 anything else like it on the market. Quest is the first truly low carb bar that doesn't contain glycerin, simple carbs, uses no sugar, and no sugar alcohols. Quest bars are the only bars that you can eat without feeling guilty.

Keeps hunger away best, because more salty than sweet. Good taste and ingredients. Recommend to order also some sweet flavor for balance.

Quest Peanut Butter Supreme

Love this flavour & find very filling. I have 2 bars per day for my protein snacks. My favourite is the Peanut Butter Supreme. Oh and also the chocolate chip one too. Thanks for having a bar low sugar, but yet high protein. Love them, fab for after a workout too.

Quest Bars

Posted by 5267442914431054922 on Feb 17, 2015

Quest protein Bars, the peanut butter supreme variety are worthy of a 5 star rating because of their yummy taste. Unlike other protein bars, Quest does not have the awful chalky after-taste. It is an ideal size which gives you enough energy and does not weigh heavy on your stomach. I am a runner who loves to exercise but finds that I am also running to my next appointment, Quest Protein Bars are ideal for someone like me who lives a busy, healthy lifestyle.
