I saw a new item last time Sean and I were at Costco. The Costco Kirkland Signature Chewy Protein Bars. These can be found in the snack section at Costco near the front of the store and the item number is 1377067.

Taste

Are these a candy bar, protein bar or granola bar? I got Sean to try these with me and we both agreed they taste like a nutty granola bar and candy bar hybrid. If you like the combination of chocolate and peanuts or peanut butter you’ll enjoy these. I’m actually shocked there isn’t more sugar per bar because these are really sweet, so sweet they taste like a candy bar! There’s a lot of peanuts so you get lots of nutty flavor. The bottom of the bars are coated in dark chocolate and there’s mini semi-sweet chocolate chips scattered on the top of the bars. To summarize what these taste like: peanuty, chocolate granola bar/candy bar.

Cost

I paid $16.99 Canadian for the box of 42 Costco Kirkland Signature Chewy Protein Bars.

Convenience

These are great for a quick snack, meal replacement or dessert. The expiry date is about nine months from the date we purchased the bars. Each bar is individually sealed.

Nutrition

These are gluten-free. One bar is 180 calories, 11 grams of fat, 16 grams of carbohydrates, six grams of fibre, six grams of sugar, 10 grams of protein and 125 mg of sodium. The ingredients list is definitely very long and not as healthy and I have no idea what fructooligosaccharides.

These are tasty but too unhealthy for me to consider them as a protein bar option to eat on a regular basis. If you’re looking for a good protein bar from Costco check out my review for the RXBAR.

Taste: 7.5/10

Cost: 8/10

Convenience: 10/10

Nutrition: 3.5/10

    • NO! I was just looking everywhere and couldn’t find them today. I even came online to try to see if maybe they just weren’t available at that particular store. These are awesome and I’m sad if they’ve discontinued them. Whyyyyy???

    • I bought these in May, but there has been a very slight reformulation, which makes almost no change in any of the “Nutrition Facts.” I disagree STRONGLY with the reviewer here,”Natalie.” She says “The ingredients list is definitely very long and not as healthy and I have no idea what fructooligosaccharides [refers to].” If only she weren’t so lazy-minded, she’d have web-searched “fructooligosaccharides”., and, at the top she would have come to https://www.healthline.com/health/fructooligosaccharides#side-effects-and-risks which makes clear that they’re natural, and that “Because they are not digestible, FOS travels intact through the small intestine to the colon (large intestine), where they support the growth of healthy bacteria in the digestive tract.” and they “May decrease cholesterol levels,” and they are “Noncarcinogenic,” and they are a “Good source of fiber,” and for almost all people there are no undesirable effects from them. Furthermore: https://en.wikipedia.org/wiki/Fructooligosaccharide says they have “sweetness levels between 30 and 50 percent of sugar.” That fact at least PARTIALLY explains the experience by “Natalie” that “I’m actually shocked there isn’t more sugar per bar because these are really sweet, so sweet they taste like a candy bar!”

      The product she recommends instead of this has NONE of these advantages, and (unlike the “Chewy Protein Bars”) is almost 100% vegan (for example, it has no eggs; instead, it has some of the best vegan sources of protein). Furthermore, what she recommends isn’t as good a value. Is that what lazy-mindedness leads one to? That’s okay for oneself, but not when evaluating something for OTHER people.

      The entire ingredients-list on this product is at least okay except for people who have allergies to almonds, coconut, milk, peanuts, or soy. And the per-ounce price can’t be beat. Nor (in my opinion), can the taste. I would give this product five stars out of five. I HOPE that it WON’T be discontinued. Ever.

  1. Fructooligosaccharides (FOS/Inulin)
    May be the healthiest ingredient on the ingredient list. FOS is a prebiotic, it’s used as a food source (like fiber) by the beneficial bacteria that currently reside in your gut. FOS helps increase the numbers of Bifidobacteria in your gut which have many clinically studied health benefits. This protein bar, along with the FOS, is the bomb!

    • Fructooligosaccharides are also a natural no-calorie sweetener and a major reason why “Natalie” was surprised at how sweet the taste of this product is. She WAY under-rated this product, which is the best snack-food bar i’ve encountered anywhere for the money — if not at ANY price.

  2. Fructooligosaccharides are subtly sweet and low-calorie. They are nondigestible, so they don’t have an effect on blood sugar levels. FOS may also have multiple health benefits.

  3. Your nutritional rating for this product is nonsensical. The RXBAR you recommend instead, and gave a 9.5/10 nutritional rating to, has only 2 grams less fat, but 11 grams more sugar than this product. Yes, it has a much simpler ingredients list, but that isn’t its nutrition. If you want to rate how natural a product is, make that it’s own rating.

    • Hi! RX bars don’t contain any unnatural sweeteners or sugar, in my opinion nutrition is eating less processed foods. The sugar in RX bars is coming from dates. Everyone has their own opinion and I love hearing others thoughts 🙂 thanks for commenting!

      • You expressed surprise at how sweet the bar is, and then condemned the bar for containing what is probably the most-healthful non-caloric sweetener, fructooligosaccharides, which, moreover, is a perfectly natural sweetener. Does that make sense?

  4. Hmm I’m surprised about your rating for nutrition. Sure the taste may make you feel guilty but this has a lot of protein and fiber for a bar of its size and taste. But I agree kind of, that at 190 calories and the %age of fat is not great.
