Bulletproof Collagen Protein Review - 16 Things You Need to Know

There’s certainly no shortage of protein powders on the market today, and choosing the right one depends a lot on your goals and your budget. It can be overwhelming to know the difference between milk protein, soy protein, and collagen. It can be even harder to figure out which one is best for you. That’s why our researchers have done the work for you.

Bulletproof Collagen Protein claims to be a super-digestible form of protein powder that can help with weight loss and recovery after exercise. Since there are so many protein products out there, we had to determine if these claims were reasonable. We looked at the ingredients and their side effects, and the research behind each of them to see if it could live up to its claims. Then, we condensed and summarized our findings for you in this review.

Bulletproof Collagen Protein can be purchased through their Official Site.

What is Bulletproof Collagen Protein?

Collagen is the connective tissue present in all body structures, including her hair, skin, nails, bones, and heart. It is the largest and most abundant protein in the body, making up nearly 65% of the protein found in our body.

The collagen acts as scaffolding, which is the glue that holds the body together.

Without it, the body would fall apart, and it’s the reason our bones and wounds heal. As we age, our body’s collagen production slows down, contributing to skin wrinkles and sagging.

The idea is that adding collagen to your meals everyday replenishes your body’s vital amino acids, which are essential to supporting the body’s ability to maintain healthy skin, joints, and bones.

They also have products like Bulletproof Coffee, bone broth, protein bites, collagen protein boosts, and bars.

Before digging deep into Bulletproof, we wanted to take a look at how amino acids impact health.

  • International Journal of Molecular Science – “Branched-chain amino acids (BCAAs), including leucine (Leu), isoleucine (Ile), and valine (Val), play critical roles in the regulation of energy homeostasis, nutrition metabolism, gut health, immunity and disease in humans and animals.”
  • Cell Metabolism – “Amino acids are fundamental building blocks supporting life. Their role in protein synthesis is well defined, but they contribute to a host of other intracellular metabolic pathways, including ATP generation, nucleotide synthesis, and redox balance, to support cellular and organismal function.”
  • Nature – Evidence also shows that amino acids work to support gut health.

How Did Bulletproof Collagen Protein Start?

There is little information on the official website about how the Bulletproof company got started. The about us page is more about their mission and the reason for its name.

According to the website’s copyright information, we’re guessing the company first started in 2013, and believe this to be one of their flagship products.


Bulletproof Collagen Protein Claims

Bulletproof Collagen Protein claims to provide a complete protein source useful to boost your overall protein intake. The powder is fine enough to add to recipes such as pancakes, so you don’t have to be making protein shakes and smoothies constantly.

Bulletproof Collagen Protein ingredients


Typical Amino Acid Profile

  • Alanine
  • Arginine
  • Aspartic acid
  • Glutamic acid
  • Glycine
  • Histidine
  • Hydroxyproline
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Proline
  • Serine
  • Threonine
  • Tyrosine
  • Valine
  • Hydrolyzed collagen


Alanine is an amino acid that helps the body convert simple sugar into energy and eliminate excess toxins from the liver, based, in part, on PubChem L-Alanine. Alanine has been shown to help protect cells from being damaged during intense aerobic activity when the body cannibalizes muscle to produce energy.

It is crucial for preserving balanced levels of nitrogen and glucose in the body, which it does through a series of chemical reactions called the alanine cycle. During the cycle, any excess amino acids in the tissues or cells are transferred to a receptor molecule, produced by the breakdown of glucose.

The receptor molecule is then converted to alanine and transfer to the liver. The liver extracts nitrogen from the alanine and converts some of it back into pyruvate and can then produce more glucose.

Any excess nitrogen is then converted to urea and passed out of the body during urination.

This cycle helps Supply the body with energy when it needs to support cellular life.


L-Arginine is another amino acid obtained from the diet and is necessary for the body to make protein. It is found in red meat, fish, poultry, and dairy products. It can also be made in a laboratory and used as a medicine.

It is used for heart and blood vessel conditions such as congestive heart failure, high blood pressure, and chest pain.

It can also be used for recurrent pain in the legs due to blocked arteries, decreased mental capacity in the elderly erectile dysfunction, and male infertility.

Some people use it to prevent the common cold, improve kidney function after a kidney transplant, and preeclampsia or high blood pressure during pregnancy.

It can also be used to improve athletic performance and boost the immune system and prevent inflammation of the digestive tract in premature infants.

It is used in combination with several over-the-counter and prescription medications for various conditions.

For instance, you can use L-Arginine along with ibuprofen as a treatment for migraine headaches.

Glutamic acid

As stated on PubChem, Glutamic acid is a non-essential amino acid occurring naturally in the L form. It is the most common excitatory neurotransmitter in the central nervous system.

Glutamic acid, also referred to as glutamate, is one of the key molecules in cellular metabolism.

It’s believed that glutamic acid is involved in standard cognitive functions like learning and memory in the brain.


Glycine is a non-essential amino acid because the body can make it from other chemicals. You can find it in meat, fish, dairy, and legumes.

Glycine is used to treat sleep problems and protect the kidneys from harmful side effects from certain drugs used after organ transplantation.

It can also protect the liver from the harmful side effects of alcohol.

Glycine may also be used to enhance memory.

Some people apply it directly to the skin to treat leg ulcers and heal other wounds, Clinical and Experimental Medicine explains.


Leucine is one of three branched-chain amino acids the body naturally uses for muscle building.

Bulletproof Collagen Protein - Amino Acids


Isoleucine is another one of the three BCAAs. It helps induce muscle protein synthesis and increases glucose uptake and the use of glucose during exercise.


Lysine is an amino acid or building block of protein that’s used to make medicine. It is used to prevent and treat cold sores caused by herpes simplex. According to the Journal of the International Society of Sports Nutrition, it is taken by mouth to improve athletic performance.


Methionine is an amino acid found in meat, fish, and dairy products. It plays a vital role in many cellular functions. It is often used to prevent liver damage in acetaminophen (Tylenol) poisoning.

It can also be used to increase the acidity of urine and improve wound healing.

Phenylalanine is another amino acid found in meat, eggs, cheese, fish, and milk.


Proline, also known as L-Proline, is a non-essential amino acid, meaning the body can make it from other chemicals.

Proline, according to the Journal of Nutrition, is an integral part of collagen formation, tissue repair, blood pressure maintenance, and arteriosclerosis (hardening of the arteries) prevention.

Does Bulletproof Collagen Protein Work?

Yes, it does work to provide a lot of protein for your diet. It can work as a meal replacement if you add fiber. It can also work to help you build more muscle. The more lean muscle you have, the easier it is to burn fat.

Bulletproof Collagen Protein benefits


Bulletproof Collagen Protein Benefits and Results

Eating enough protein is an essential part of a healthy diet, especially if you’re trying to lose weight.

If you don’t have enough protein in your body, your body will start to break down the muscle in your body for energy, which though you’re losing weight, tends to backfire in the end because you want the more lean muscle to boost your metabolism.

Details on Bulletproof Collagen Protein and Weight Loss

It is not a fat burner or an appetite suppressant, so it’s not for weight loss. However, it can be used as a meal replacement when combined with fiber and healthy fat.

When part of a nutritionally balanced diet, it may help facilitate weight loss.


How to Use Bulletproof Collagen Protein

Mix one scoop into a glass of water or milk. Drink. Follow recipes as shown on the official website, including extra protein and collagen into the food you eat.

Bulletproof Collagen Protein side effects

Side Effects

Potential Bulletproof Collagen Protein Side Effects

High calcium levels or hypercalcemia may occur as a side effect of taking too much collagen.

It can lead to:

  • Constipation
  • Nausea
  • Vomiting
  • Fatigue
  • Abnormal heart rhythm

Too much collagen can also lead to hypersensitivity reactions, an abnormal response to the immune system against allergens.

It is most common when collagen supplements come from marine sources.

Bulletproof Collagen Protein Product Warnings

In addition to the California Prop 65 Warning, children and women who are pregnant or nursing should not use this product.

If you take medication for any medical condition, speak with a doctor to make sure you can use this product.

Any Bulletproof Collagen Protein Lawsuits?

According to the FDA, in 2017, Bulletproof 360 recalled individual collagen protein bars and bites due to potential contamination.

Someone filed a class-action lawsuit against Bulletproof in August of 2019. The suit covers many issues with the company itself and its products, including Bulletproof Collagen Protein, which claims to make “unauthorized nutrient content claims,” according to Truth in Advertising.

Bulletproof Collagen Protein Alternatives

There are many other collagen protein supplements available on the market today, including:

  • Pure Collagen Peptides Powder
  • Vital Proteins Collagen Peptides
  • Dr. Axe Multi Collagen Protein

Bulletproof Collagen Protein vs. Vital Proteins

Both of these use pasture-raised, grass-fed bovine collagen. You can get Vital Proteins in smaller and larger quantities ranging from 5 ounces for $15 to 20 ounces for $43, making it a slightly better value in terms of cost. There’s also the option to get it in capsule form, for those who aren’t keen on the idea of making protein shakes or using it in recipes all the time.

Bulletproof Collagen Protein vs. Collagelatin

Both of these products are from Bulletproof. The main difference between them is that Collageletain is made with beef gelatin and has collagen added. It’s job is to support weight management, healthy bones and joints, and glowing skin.

It’s supposed to support rapid tissue repair. It’s also useful in recipes because it can thicken sauces and make gummy vitamins. It mixes easily in hot liquids and gels when it’s cool. It is the same price as the collagen protein, for the same quantity. Gelatin is not a vegetarian or vegan-friendly product.

What Users Are Saying

“I’ve tried a multitude of collagen powders to achieve relief for painful joints, but to no avail. On this journey, I reluctantly tried the Bulletproof Collagen Protein Powder. OH MY GOSH! Within a matter of a few days the joint pain in my hands was remarkably improved. I eventually experienced so much relief that I was even able to go off of liquid glucosamine.”

“After reading about the benefits of collagen and this product in particular, I tried it. It does mix well in my hot tea and does not have a taste. It gave me a feeling of fullness as well. But the side effect of constipation really was problematic. I went on and off the collagen over the course of months to see if that really was the problem. Yup. It caused terrible constipation for me.”

“It didn’t seem to help with my joints at all. I had hoped it would.”

Bottom Line

The Bottom Line on Bulletproof Collagen Protein

Using an upgraded collagen protein supplement may be better for your stomach than other protein supplements out there, especially if you’re allergic to milk products and don’t want to rely on soy-based proteins. However, a basic protein supplement will not provide the same weight loss results as one that contains a clinically tested fat burner and appetite suppressant. If you lack enough protein in your diet, you will struggle to reach your goals, which is why something like this could help you.

If you’re tired of fad diets and looking to shed those extra pounds for good, finally, we suggest opting for a product that will save you money in the long run because it’s made to be the last weight-loss program you’ll ever need.

One of the best weight-loss apps we’ve seen so far this year is Noom. Its methods are clinically proven to help you lose weight and keep the weight off. With human coaching and personalized meal plans, it’s no wonder our researchers could find plenty of users who report experiencing impressive results.

If you want to see how it could work for you, the makers of Noom are so confident that you’ll get the results you’re looking for that they are offering a free trial offer, which is always a good thing.

  • Renee M Kabat (Verified Purchase)

    I just started to use the Bulletproof Collagen Protein powder so I am not feeling a real difference just yet. I will say however that Bulletproof has excellent customer service, they go out of their way to make sure customers are satisfied. I did not like the taste of the chocolate protein powder so they sent me unflavored for free and I didn’t have to send back the chocolate so I gave that away to a friend. I love their coffee, and have been making bulletproof coffee with the collagen powder every morning. Highly recommend giving them a try!
