The Bottom Line

Quest nutrition bars can be a tasty and healthy addition to a low-carb diet, especially when convenience is a factor. The bars are sweetened primarily with natural ingredients, with a very small amount of sucralose. They are chewy, and with a pleasant caramel-like background flavor, and a mild peanut or almond flavor. I have checked my blood glucose after eating them, and there is no rise in blood sugar. The only real downside is that the chicory root fiber can cause gas in some people.


  • Very good-tasting
  • No sugar alcohols, including maltitol
  • Low-glycemic, sugar-free, and low in carbs
  • No soy or gluten
  • Manufacturer will supply two free bars so you can check them out


  • Must mail order
  • On the expensive side (but no more so than similar bars)
  • Chicory root fiber gives some people gas (but not most, and the body can adapt over time)


  • Comes in two flavors, with more under development - Vanilla Almond Crunch and Peanut Butter Supreme
  • 4 grams of non-fiber carbohydrate (from the nuts) in the Vanilla Almond Crunch, and 5 grams in the Peanut Butter Supreme
  • 20 grams of protein per bar
  • 230 calories in the Vanilla Almond Crunch, and 220 calories in the Peanut Butter Supreme
  • 15 grams of fiber, mainly from chicory root fiber, per bar
  • Sweetened mainly with inulin made from chicory root, with small amounts of Lo Han Guo (a fruit extract) and sucralose.
  • Gluten-free and soy-free

Guide Review - Product Review: Quest Protein Bars

It turns out that making a low-carb nutrition bar without a lot of artificial ingredients is quite difficult. The main issue is to make it shelf-stable - we can always come up with delicious recipes in our own kitchens, but we know that they aren't going to last on the shelf for months! Such was the dilemma of the makers of Quest bars. They had been following a low-carb way of eating for 12 years, but were totally dissatisfied with the bars on the market, so they decided to see if they could develop one. It turned out to be a long and winding road (experts kept saying, "It can't be done"), and they ended up getting a patent in the process!

The result, I'm happy to say, is really quite wonderful - a good-tasting bar without objectionable ingredients! The only negative at all is that the inulin in the chicory root, which is quite good for you and is a prebiotic, also causes gas in some people. The reason is similar to why beans tend to cause gas. In an extremely unscientific survey, I have talked to a dozen people who have tried the bars, and 5 of them report this gas. However, (and also similar to beans) over time the body tends to adapt to inulin so that less or no gas is produced. (Update: I did end up adapting! No more gas!!)

More good news - the makers of Quest Bars are offering two free bars so that you can try them for yourself! The only caveat is that at the time of this writing it will take several weeks to get them, as they explain on this page. If you are in a hurry, they will pay the shipping on your first order of bars instead.

Great bars!, Guest mrausch

These bars are so delicious and packed with protein. I didn't find them too sweet as one reviewer did and I'm a ""salt person"" overs sweets. They are a nice change to eggs for breakfast everyday :) I keep one in my purse, and several at work and home for that time when I do get a sweet craving. I usually only end up eating half because they are filling. They come in many many more flavors since the time Laura reviewed them. And you can also buy them at your local GNC (vitamin store).
