These days, there are so many different collagen supplements out there, usually in the form of powders.

But there are also many other options becoming increasingly available now, such as protein bars. And one such option is called Bulletproof Collagen Protein Bars.

Are these protein bars the tasty, health-boosting treat you’re searching for? In this Bulletproof Collagen Protein Bars review, we’ll discuss everything you need to know about these bars to find out if they’re right for you.

Let’s jump in!

About Bulletproof Collagen Protein Bars

Bulletproof Collagen Protein Bars are made and produced by the well-known supplement company Bulletproof. This company is a popular option in the health and wellness industry and have produced a variety of other options, many of which we have reviewed.

Other Bulletproof reviews:

Bulletproof Collagen Protein Bars are designed to be an easy, tasty way to get in high-quality nutrition and health benefits.

Each of these bars is made with grass-fed collagen protein, totaling 11g of protein per bar (the same source of collagen they use in their regular Collagen Protein powder). 

Plus, they have other healthy ingredients, such as cashew butter and MCT oil for healthy fats, and inulin for quality fiber (with 8g of fiber per serving!). Not to mention every bar is under 200 calories and has only 2g of added sugar. 

These may very well satisfy your sweet tooth, too, as they come in the following flavors:

  • Vanilla Shortbread

Support for Skin, Bones, and Joints

Skin problems, joint pain, and declining bone strength are concerns for many people, especially as they get older.

And the Bulletproof Collagen Protein Bars are advertised to support your skin, bones, and joints due to the inclusion of grass-fed beef collagen protein. At 11g per serving, this is possibly a convenient way to get in the collagen protein you desire to boost your health.

Sustained Energy

So many people choose empty-calorie snacks that are devoid of nutrients. And this can leave them with little energy to get through the day.

But Bulletproof Collagen Protein Bars are made to be different. Bulletproof claims that these bars will give you sustained, long-lasting energy with MCT oil and cashew butter.

Reduced Hunger

How often do you have a snack that leaves you hungry just an hour later?

Well, Bulletproof Collagen Protein Bars are designed to stand out from the crowd. They say that the inclusion of high-quality protein, fats, and fiber will reduce your hunger and keep you fuller, for longer.

But can these Collagen Protein Bars really be tasty and healthy? 

Read on to find out!

Bulletproof Collagen Protein Bars Ingredients

The ingredients somewhat depend on the flavor you choose. But in general, all of the Bulletproof Collagen Protein Bars have the following ingredients in them:

  • Hydrolyzed Collagen
  • Cashew Butter
  • Inulin
  • MCT Oil

And there are other natural ingredients for flavor, texture, and sweetness (depending on the flavor), such as cacao nibs, stevia leaf extract, sea salt, lemon oil, cocoa powder, and vanilla extract.

Hydrolyzed Collagen

The main ingredient in the Collagen Protein Bars is, of course, collagen!

Bulletproof uses hydrolyzed collagen from grass-fed cows. And this hydrolyzation process seems to make collagen more bioavailable.

In general, collagen is an important protein because it’s the building block in many tissues, such as the skin, joints, bones, and tendons. 

Consumption of collagen has been shown to reduce wrinkles and improve hydration, firmness, and elasticity in the skin. Not to mention it may strengthen hair and nails. (No wonder some people call it the ultimate “beautifier”). 

And collagen supplementation also seems effective for improving flexibility and mobility while reducing joint pain, joint stiffness, and osteoporosis.

Cashew Butter

Cashew butter is a rich source of healthy fats, not to mention various minerals, such as magnesium. 

The healthy fats in it may help reduce hunger and give you long-lasting energy.


MCT Oil is made from medium-chain triglycerides, which are a type of saturated fat. 

The fatty acids in MCT Oil have been shown in some cases to boost energy and reduce hunger. Although the evidence on it for weight loss is mixed.

It still seems like a healthy fat source overall, though.


Inulin is a type of prebiotic fiber. Therefore, it may boost gut health by enhancing the number and function of probiotics (good bacteria). 

Plus, inulin seems to help reduce blood sugar and cholesterol, not to mention it may reduce appetite by increasing the feeling of fullness. Although it may not have any major effects on weight loss. 

Other Ingredients

I also mentioned that there are various other ingredients for flavor, sweetness, and texture.

After scanning those ingredients, I could tell that all of them were naturally sourced; and Bulletproof Collagen Protein Bars don’t contain any artificial ingredients or added sugar. 

There is only 2g of sugar per serving and 4 to 5g of net carbs, depending on the flavor.

Are Bulletproof Collagen Protein Bars Effective?

Bulletproof Collagen Protein Bars definitely appear to be a quality collagen snack. 

These bars have a solid dose of collagen protein (11g) per serving, in addition to great sources of healthy fats and fiber that should help with energy and hunger cravings.

The total calories are pretty low, with each bar 190 calories or less, so it also seems effective for the weight-conscious.

Do Bulletproof Collagen Protein Bars Taste Good?

Yes! We were impressed with the taste of Bulletproof Collagen Protein Bars. These are definitely some of the better-tasting protein bars on the market. 

The taste of these bars makes them a great option for satiating sweets cravings without succumbing to unhealthy, sugary products.

Claims vs. Reality

Bulletproof didn’t offer any outlandish claims, and it’s safe to say that you can generally expect what they claim.

The collagen protein in these bars should provide support for joints, bones, and skin; but I wouldn’t expect any noticeable differences until you’ve used these consistently for a few weeks. And some people may not physically notice anything at all, but that doesn’t mean these bars don’t do anything.

Also, the inclusion of healthy fats and fiber (along with protein), should stave off hunger better than most snacks would. 

Not to mention the healthy fats may help give you a nice lift in energy when you need it in between meals.
