  • All of Amazon’s best-selling protein bars are back in stock right now after several popular options were sold out for the past couple of weeks, so it’s a great time to stock up.
  • Quest Nutrition Birthday Cake Protein Bars are still at the very top of the list, as they have been for quite some time, but there are plenty of other good options to choose from.
  • RXBARs and Pure Protein Bar variety packs are perennial favorites, and Atkins Meal Bars are a recent addition to the top 5 list after skyrocketing up Amazon’s best-sellers list.

Shockingly delicious Quest Hero bars are by far our favorite protein bars. They’re sweetened with allulose instead of regular sugar so they exactly like they have real sugar, but the body doesn’t metabolize allulose the same way. That means you don’t have to worry about all the calories and other problems associated with sugar. As delicious as they are, however, Hero bars aren’t among the best-selling protein bars on Amazon right now.

There are other bars out there with just as much protein that are almost as tasty, and Amazon’s best-sellers chart is full of them. Quest Nutrition Birthday Cake Protein Bars are #1 on the list right now, and they have been for a long time. RXBARs and Pure Protein Bar variety packs are also regular top-sellers, and they’re finally back in stock. Scroll down to check out the five best-selling protein bars on Amazon’s site, so you can stock up before they start going out of stock again.
