This week, we scanned Amazon鈥檚 bestseller list for outstanding protein bars, then pulled the most useful and authoritative reviews for each.
Rxbar Whole Food Protein Bar ($20 for 12)

Protein per bar: 12 grams
鈥淲hat appeals to me most about 聽is that the ingredients are clear, clean, and straightforward. Ingredients on the back match the ingredients on the front. Regardless of the specific flavor you order, most of them will have a somewhat lightly sweetened Fig Newton鈥搇ike taste. I鈥檝e found the chocolate sea salt flavor to be my favorite, so far. I think if you鈥檙e looking for a clean source of energy, then you should try this bar.鈥
Kind Bars ($13 for 12)

Protein per bar: 8 grams
鈥溌燾ame in fresh and delicious just like the bar I bought at a store to try before ordering these. I like that these have eight grams of protein as I find that a higher-protein snack stays with me longer, but with just 200 calories. The peanut butter taste is subtle, which I like.鈥
Gatorade Whey Protein Recover Bar ($17 for 12)

Protein per bar: 20 grams
鈥淥f all the bars I鈥檝e tried, the ones I keep buying and聽buying are . First of all,聽they are delicious鈥攊n both taste and texture. And they are based on whey protein, which is the best protein supplement source for humans聽from the research I鈥檝e done. Gatorade has done a good job with these.鈥
Optimum Nutrition Protein Cake Bites ($21 for 12)

Protein per bar: 20 grams
鈥淭he texture of 聽is amazing and they actually taste聽like a cake pop. Don鈥檛 expect light fluffy cake, it鈥檚 much more dense and chewy. If you go in expecting a cake pop you will be delighted! Flavor is super accurate as well. I completely understand why these are sold out everywhere.鈥
Clif Builder鈥檚 Protein Bar ($18 for 12)

Protein per bar: 20 grams
鈥溌爋n the market. The balance of protein, taste,聽and price is perfect. I often try others but never switch away from Clif聽Builder鈥檚. I am a runner and will eat one right after a long run. For really long runs, I eat one before I head out instead of my usual Clif聽Bar. The density helps as I don鈥檛 want a heavy amount of food and I can鈥檛 stop and eat. These do the trick.鈥
