Best quality protein bars

In terms of quality ingredients, Quest Protein bars are unparalleled in both the sports nutrition and health markets. They only use 20g worth of whey protein isolate and milk protein isolate. No lesser quality protein or fillers which are commonly used to bump up amino acid profiles. Its also a low-net carb/sugar bar with 4-6g of non-fiber carbs and 1-3g sugar. The natural line (they make two lines) is the way to go if you do not want sucralose, which they use a very trivial amount of. The natural line is sweetened naturally with stevia, lo han guo and erythritol. Almond butter is the base of the bar, and most sugars/carbs come from the almonds.

They make 11 total flavors (5 natural line) and my favorites are Cinnamon Roll and Coconut cashew. The natural line bars tend to be much softer and chewier out of the wrapper. Typically people microwave the harder bars for a few seconds and they come out very moist and soft, such as the Chocolate Brownie or Apple Pie.

This is the ingredient list for Coconut Cashew:
Whey Protein Isolate, Milk Protein Isolate, Isomalto-Oligosaccharides, Almonds, Water, Erythritol, Coconut, Cashews, Sea Salt, Natural Flavors, Lo Han Guo and Stevia.

My second favorite bar in terms of quality (and taste) is the VPX Zero Impact bars, which are higher calorie meal replacement bars. In actuality, they are closer in texture to brownies and offer two very tasty, rare flavors: German Chocolate and Pumpkin Pie (both of which taste very good a few seconds in the microwave). Their ingredient list is a lot longer, but they rank among the top in regards to quality ingredients.

I'm also all for the Quest bars. They have so much fiber in them and taste great if you microwave them! I haven't tried all the flavours but definitely love the Chocolate brownie and peanut butter chocolate ones.
