Quest Protein Bar review

Quest is the established choice for low-carb snackers. The Chocolate Chip Cookie Dough bar, one of the brand's best sellers, lists 21 grams of protein, 190 calories, 12 grams of dietary fiber, 1 gram of total sugars and 0 grams of added sugars in a 60 gram bar, and Quest labels it keto-friendly. The protein is milk protein isolate and whey protein isolate, and most of the fiber comes from polydextrose, a prebiotic fiber. The 6 grams of sugar alcohols include erythritol. Quest sells a 4-bar box for $12.49, which makes it cheap to test a flavor, and a 12-bar box for $35.49, about $2.96 a bar; subscribers save 15%. The flavor list runs from cookie dough to seasonal Pumpkin Pie, and the brand suggests 15 seconds in the microwave to soften a bar. The catch is texture and price: Quest bars are firmer than Barebells, and free shipping starts at $99.
