Costco RXBAR Protein Bar Review

Are you looking for a protein bar with just a few simple, clean ingredients and no added sugar? The Costco RXBAR might be just what you’re in search of. The bars are full of nutritious ingredients and have 13 grams of protein. Find out below how these RXBAR taste and if they’re worth your hard-earned money!

I’m trying to review a few more healthy finds from Costco for people who are trying to watch their weight or be mindful of their health. There are so many different diets right now: low-carb, high-fat, high-protein, paleo and keto just to name a few.

I originally reviewed these protein bars up these RXBAR Protein Bars in 2019 and picked them up at Costco because I liked the sleek packaging and also appreciated the “No B.S” ingredients list. The “No B.S.” slogan is used by RXBAR in marketing these protein bars.

I’ve now been eating them regularly for almost three years and they were a staple snack item during my recent pregnancy! Costco has added an additional peanut butter flavor bar in the box, so I want to update my review.

Each bar has twelve grams of protein.

Other snack and protein bars I’ve reviewed from Costco are the Costco MadeGood Chocolate Chip Granola Bars, Costco That’s It Mini Fruit Bars, Costco No Sugar Company Keto Bars, Costco Quest Protein Bars, Costco Kirkland Signature Soft & Chewy Granola Bars, Costco Kirkland Signature Protein Bars, Costco Clif Kid ZBar and the Costco Nature’s Bakery Fig Bars.

Location in Store

You can find the RX bars in the snack section near the checkout lines with the other protein and snack bars. The item number is 3305275.

Taste

There are two different boxes you can purchase at Costco and each box comes with two flavors. Chocolate sea salt and chocolate coconut in one box. Chocolate sea salt and peanut butter chocolate in the other.

The peanut butter chocolate flavor has peanuts instead of almonds.

First, I’ll start with a quick warning. If you’re like me and have a wire on your teeth from when you had braces, be prepared for this seriously sticky chewy bar to get nice and stuck to it! Seriously though, metal wire or not, these protein bars will stick to your teeth and also give you quite the mouth/jaw workout. They’re very, very chewy and sticky!

Now that I’ve informed you of how chewy these bars are, let’s talk about taste. The bars taste basically like the simple ingredients listed on the package melded together and formed into a bar.

The chocolate sea salt is lightly sprinkled with, of course, sea salt, and the chocolate flavor is quite mild The taste of dates is most noticeable and they’re quite sweet.

The coconut chocolate has chunks of chocolate and a strong coconut flavor. You can taste the notes of dates and egg whites slightly, but not much.

The peanut butter chocolate has a nice strong peanut butter flavor with mild hints of chocolate, it kind of tastes like a more healthy sweet version of a candy bar. I think it’s my new favorite.

The nuts add some nice crunchy texture to the bar and compliment the chocolate. In terms of sweetness, these protein bars aren’t overly sweet. The sweetness in the bars comes from the dates. Dates are naturally quite high in sugar.

Don’t expect the RX bars to taste similar to some protein bars that taste like cookie dough or a brownie, those ones don’t contain just a few natural ingredients.

Cost

The box contains 14 bars (seven of each kind) and costs $23.99 Canadian. That’s less than $2.00 Canadian per bar. These definitely aren’t cheap, but unfortunately not a lot of foods marketed as being healthy or “clean” are. They’re not as expensive as some protein bars which can be about $3.00 per bar or more!

Convenience

You can’t beat any sort of bar-type snack for convenience. As a healthy protein bar, these are perfect for a snack or breakfast on the go! They’re also great for refueling after a workout or as a junk food replacement to curb cravings.

I wanted to try to eat healthy during my pregnancy but also get in enough calories and fat and the RX bars were my go-to snack or dessert. The best before date listed on the box is six months from the date we purchased the bars and each bar is individually wrapped.

Because the bars are wrapped individually it’s convenient to put them in your purse, desk at work, diaper bag or bring them when you travel!

Ingredients

The ingredients list is very simple and I know what each and every ingredient is! That’s really the main selling feature of these protein bars.

The bars are gluten-free as well as dairy-free which is a major bonus! They may contain tree nuts, peanuts, eggs, milk, soy and wheat. I like that they have healthy fats from the nuts and protein from egg whites.

Overall

Must buy!

I’ve eaten a lot of RXBARs since I first tried them, and the taste has grown on me. I find when I’m eating mainly healthy, things like an RXBAR tastes like a treat. When I’m overdosing on junk food (especially chocolate!), I find bars like this don’t taste as great.

If you’re trying to eat healthily and want a pretty tasty, healthy snack bar option, I’d recommend that you check these out.

Do you have a favorite brand of protein bars?

  1. I’ve considered buying these in the past, but haven’t tried them or know anyone that buys them. I will pick some up next time I’m in Costco, after reading your review. Thank you!
    Also, congratulations on the birth of your baby girl!

  2. I tried these last year. Wasn’t crazy over them at first, but like you, when I cut down on candy they started tasting better and I ate all of them! Looking forward to trying the new one.

  3. I was misled while being in a hurry to shop. Looked at the daily value line and it listed nothing for sugar and 0 for added sugar. Got the product home and found it includes 13 grams of SUGAR, what a bummer. So angry I was easily misled.
