Bulletproof Collagen Review 2021

Our Verdict

A keto-friendly protein powder made with collagen protein and over 15 amino acids to support joint and overall health.

Pros & Cons

With so many nutrition companies competing for online leadership, it can be complicated to filter out the good and the bad features behind a product.

Add to that, the massive amounts of data and scientific research backing these companies, some of which is hard to contextualize.

Comparing keto-friendly collagen protein powders doesn’t have to take a Ph.D to pick the best product for you.

Let’s check out the pros and cons of Bulletproof’s powder.


  • Attention to ingredient sourcing is transparent and honest, giving customers proof of their grass-fed, pasture-raised cows
  • The ingredients list has only the collagen in it. 
  • There’s no added sweeteners.
  • Competitive pricing.


  • Consuming collagen protein has been linked to low risk side effects like heartburn, upset stomach, and diarrhea.
  • Since the protein comes from cows, it’s unfortunately not a vegan product.

It seems like there are dozens of protein powders out there that promise healthier skin, nails, and joints similar to Bulletproof Collagen Protein.

Many of these promises come up short on first use. With so many choices, what’s the best way to ensure you find a quality powder?

In our review of Bulletproof Collagen Protein, we’re going to research the amino acids, ask if it’s keto-friendly, and check out the health benefit claims.

We’ll provide an easy-to-understand explanation of what Collagen protein is and how it stimulates the body.

We’ll also look into the ingredient sources in this product--because isn’t knowing where your protein comes from just as important as knowing what it is? 

What is Bulletproof Collagen?

Bulletproof Collagen review

Bulletproof Nutrition claims their powder has several benefits:

  • Stimulating the body to create more collagen, which it produces less with age
  • Improving the skin’s glow and suppleness
  • Aiding in joint and bone growth
  • It comes with 20g of super-digestible protein per portion

The benefits this powder carries are primarily due to Collagen, the body’s most abundant protein. By stimulating our naturally-produced Collagen, Bulletproof claims that this product can aid protein production, plus skin, bone, and joint health.

Collagen is sometimes called the ‘glue’ of the body because it’s vital to the structures that connect our organs, bones, and skin. Collagen makes our skin supple, hydrated, and it also prevents environmental toxins from spreading across cells.

Collagen makes up a whopping 30% of our proteins, too. With that kind of presence in our body, no wonder collagen powders and creams have gotten so popular!

By ingesting a protein powder like Bulletproof in meals and beverages, you’re providing your body with the amino acids that make up proteins like collagen.

Since collagen doesn’t replenish itself as much with age, collagen supplements are a good preventative measure.

Ingredients & Nutrition Facts

Bulletproof lists only one ingredient in the collagen protein powder--hydrolyzed collagen powder. That’s right: the company has eliminated excessive fillers, preservatives, and a lot of the extra ingredients which powders with less pure sources pack into their mix.

This collagen protein comes from pasture-raised cows without added hormones. 

This product is 100% Keto-friendly, so almost any special diet can incorporate this product without changing diet plans or macros.

Bulletproof also adds that the powder is enzymatically-processed several times before being packaged, which increases the density of the collagen’s peptides. 

  • Serving Size: 2 Scoops (3 2/3 Tbsp/20g)
  • Servings Per Container: about 25

At 20g of collagen protein per 2 scoops, this powder packs a lot of protein in a small portion, though it is on par with other highly-reviewed competitors’ products.

The total amount of protein in the bottle comes out as 500g.

Also, this powder is low-carb, making it suitable for people looking out for protein supplements that aren’t chocked-full of sweeteners and sugar.

Nutrition Facts

Per serving (2 scoops), Bulletproof Collagen contains:

What Does Bulletproof Collagen Taste Like?

Of course, one of the most important components for a great protein powder to have is a great taste. And since it’s impossible--usually--to taste test a product like this without investing in a bottle right off the stockroom shelves, let’s take a look at some testimonials.

Bulletproof claims that their collagen powder is unflavored. Therefore, they claim that you can add the powder to hot or cold beverages, soups, smoothies, and even coffee without a noticeable flavor.

Out of 1649 reviews available to read online, an overwhelming majority of customers highly recommend the product’s taste--rather, the lack of it. People love it in coffee, add it to fruit smoothies, and notice no aftertaste either. 

Add to the great taste, many testify that the powder mixes to drinks without lumps or a sticky residue. Finally, customers also praise its lack of odor. It seems to be a very inoffensive product.


Shopping for collagen protein powders doesn’t need to take all day. Although there are many powders out there that offer similar benefits and ingredient sources, let’s look at some common questions that users of the Bulletproof powder in particular asked.

Added to drinks, soups, or even used as a meal replacement if you add fiber, users consistently approve of the Bulletproof powder and say it works. Many users were satisfied with the smoothness and glow in the skin. It also helps build muscle, strengthen joints, speed recovery after workouts.

What can you mix this protein with?

Bulletproof’s powder is flavorless, and customers almost unanimously agree. Some people add the powder to a morning coffee, and many others put it in with a daily post-workout shake. It can be added to hot liquids too--for instance, add it to soups and broths.

When is the best time to take Bulletproof Collagen?

Research shows that timing matters when consuming collagen protein, whether you're working out or aiming to alleviate health conditions. Basically, it depends on your needs. Take collagen before exercise if you experience joint pain. Take it before bed to improve sleep. However, many users can take it anytime and experience improved health.

Does Bulletproof offer a money back guarantee?

 Yes. Products purchased online can be returned before 30 days with authorization.
