Boasting a hefty 11g of grass-fed hydrolyzed collagen in each bar, Peak Performance offers a high-quality and brownie-like taste and texture.

Additionally, each bar is 220 calories and 11g net carbs.

What's really unique about Peak Performance's Grass Fed Collagen Protein Bar is that it's 3rd-party tested for quality. Most bar providers don't take this extra step because of the additional cost.

Peak Performance doesn't use any artificial sugars (they use Stevia, a natural sugar replacement), sweeteners or refined flours. 

They use real food ingredients that are non-GMO, gluten-free and easily digestible.

Honestly, there's nothing significant we don't like about the Peak Performance Collagen Protein bar, including the 100% Happiness Guarantee.

The next protein bar in our review is from ZEEBAR. Currently, they offer one flavor: almonds and raisins.

First off, it is one of the lowest cost per ounce offering compared to the other bars we reviewed.

Second, it does offer the highest protein count per bar at 18g (14g of hydrolyzed collagen from grass-fed cows).

Third, each bar is 250 calories, 14g of fat and 13 net carbs.

What's unique about the ZEEBAR is they add argan oil to their bars.

If you don't like raisins or more of an oily texture, you may not like these ZEEBAR.

  • Argan oil added
  • One flavor available
  • Higher carb count
  • 'Oilier' texture

How about a protein bar that's also a beauty supplement? Created by two professional models, Kalumi offers just that in their cocoa kiss flavor marine collagen protein bar.

One of the best-tasting collagen protein bars in our review, the bars are a dark chocolate brownie with crunchy cacao nibs--chocolate and crunch!

Kalumi uses marine collagen in their protein bars, a full 12 grams of protein per bar. The marine collagen used in this bar is from premium, wild-caught fish and other all-natural ingredients. The sweetener used comes from yacon syrup and sweet potatoes. 

Furthermore, the bars are gluten-free and kosher.

The biggest downside of these bars is their high price at 9 bars/box.


  • 12g highly bio-available marine collagen/VAR
  • Developed by professional models
  • Beauty supplement and protein bar
  • Chocolate and crunch
  • Sweetened through vegetables

The final good-tasting, high-quality collagen bar in our review is great for those who are on a keto-based eating plan.

The MCTCo collagen protein bar comes in three delicious flavors, caramel sea salt, cookie dough and cocoa. Each bar tastes like you're enjoying dessert without dinner.

Each bar contains a generous 10g of grass-fed bovine collagen, 5g of high-quality MCT oil from coconuts (never from palm kernel oil) and 2g of net carbs.

All ingredients in the MCTCo Keto bar are natural, non-GMO and gluten-free.

Other than no stated money-back guarantee, there's nothing we found that would cause someone not to try this bar.


  • 10g collagen/bar
  • Includes MCT oil for steady energy
  • Low net carbs
  • 3 flavors
  • Medium-priced

6. Bulletproof Collagen Protein Bar

Click on the image for more information


One of the things we really like about Bulletproof is they offer their collagen protein bars in multiple yummy flavors: NEW berry cobbler, lemon cookie, cookie dough, fudge brownie, mint chocolate chip and vanilla shortbread.

For this review, we'll focus on the lemon cookie flavor (a personal favorite).

Each lemon cookie bar contains 12g of protein sourced from grass-fed collagen (bovine), only 2g of sugar that comes from organic cashew butter and inulin. The net carbs is 9g. There is 14g of quality fats from organic sources.

Specifically, their bars also feature Bulletproof's proprietary Brain Octane Oil and XCT Oil which includes coconut oil. Coconut oil has been shown to be a reliable source of energy from fats, which is a better option for your body than sugar or caffeine.

One thing we know about this bar is that it breaks easily into smaller pieces. Therefore, it may not be the best choice for travel.


  • 12g collagen protein/bar
  • 5 flavors
  • Proprietary MCT & Brain oil included for energy and brain management
  • Bars break easily


In our review, we researched the best tasting  collagen protein bars available on the market today. Each bar we reviewed is of high-quality and tastes great! Otherwise, what's the point?

Overall, the winner in our review was Peak Performance Grass Fed Collagen Protein Bar.

Assuming everyone loves the chocolate brownie flavor, the grams of collagen and lower net carbs led our editors to choose this option as the healthiest protein bar in our review.

Coming in a close second was MCTCo Collagen Protein Keto Bar, let us explain why.

We liked the collagen count in this bar, it's moderately priced and includes MCT oil.

MCT oil helps with energy management without the jitters of coffee or crash after consuming sugar. 

No one wants to look forward to a delicious protein bar only to be disappointed by the taste.
