We know that when tasting them for the first time, most people have a hard time believing that Universal Nutrition Doctor's Diet CarbRite Bars are good for them. We know that because we did too! These delicious bars are loaded with protein but have little or no sugar. That's exactly what most bar customers are looking for. If you've tried other high-protein low-sugar bars and been disappointed by the taste, don't give up on bars just yet. Try a box of the awesome Doctor's Diet CarbRite Bars and see why they outsell other bars by a huge margin. Note: Due to consistent high demand, the availability of some quantities and flavors may be temporarily affected.
