I see how strong my nails are, I see the new hair growth — even my hairstylist has mentioned it.

Joint and bone support

Collagen Protein is a key building block for strong, high-performance bones and joints.

My hair is as thick as it was when I was 25! I just turned 50!

Mixes easily in hot and cold drinks

Mixes in hot or cold drinks

Add to hot soups or Bulletproof Coffee for an extra frothy cup. In cold drinks, Collagen Protein is your new favorite mix-in.

My morning is not complete without a scoop of this collagen powder. It doesn’t change the taste of my coffee. It makes me feel great and keeps me full. I notice when I don’t have it.

Collagen is loaded with amino acids, including glycine, proline and hydroxyproline. Your body uses those amino acids to make more collagen protein.

Whey protein is different because it also contains tryptophan. Think of collagen protein as a way to fill in the gaps and make sure your body is getting high enough doses of the amino acids it needs to build more collagen.

Some people combine whey and collagen protein — that way, you get all the amino acids your body needs, plus an extra kick of joint and bone support from collagen. Learn how to choose the best protein powder for your body.

Bulletproof Collagen Protein is primarily type I and a small amount of type III bovine collagen.

There are at least 28 different types of collagen, but types I, II and III form 80-90% of the collagen in your body. Type I and III provide structure to your skin, muscles and ligaments. [7]

Bulletproof Collagen Protein is made up of collagen peptides that have been hydrolyzed, or broken down into an easy-to-digest powder. Thanks to hydrolysis, Collagen Protein easily dissolves in hot and cold liquids and it won’t form a gel when cooled.

Collagelatin is a blend of collagen protein and gelatin. It forms a jiggly gel when it’s dissolved in hot liquid and cooled. The benefit of Collagelatin is that you get the gelling power of gelatin with added protein from collagen. Use it to make protein-packed gummy treats, or as a versatile thickener in soups and sauces.

We recommend 1-2 scoops. One serving (2 scoops) of Bulletproof Collagen Protein contains at least 22 grams of pure hydrolyzed collagen. You can take it any time of day — try one scoop in your morning coffee and one scoop before you head to bed.

A well-balanced diet rich in collagen protein and the amino acid cysteine promotes faster and thicker hair growth. You get cysteine from high-protein foods like meat, eggs and broccoli. For the best hair ever, follow a balanced diet and try a collagen supplement.

Studies show that collagen can strengthen joints, improve flexibility and decrease mild joint pain after exercise.

The primary benefits of collagen include smoother skin, thicker hair and nails and stronger joints. Collagen is a great hack for endurance athletes, especially if your preferred exercise is tough on the joints — looking at you, endurance runners and powerlifters.

“Hydrolysis” means breaking a hydrogen bond. To make collagen protein, we take gelatin and use gentle enzymes to break it down a step further into hydrolyzed powder. That process allows the final product to easily dissolve in hot or cold liquids, which is great, but it also maintains the nutrition of the collagen and maximizes bioavailability — which means your body can actually absorb those essential amino acids and produce more collagen.

Yup. Bulletproof Collagen Protein dissolves easily in hot and cold liquids. The only exception is Collagelatin. Just like those gelatin packets you can buy at the grocery store, Collagelatin dissolves in hot liquids and then gels when cool.

Bulletproof Collagen Protein doesn’t taste like anything. It’s also odorless, in case you were wondering. Once you add it to your favorite drinks and recipes, it’s virtually undetectable (but your body will appreciate it).

Bone broth is tasty and savory, but it also takes hours to properly prepare. Collagen protein contains the same amino acids as bone broth and it’s way easier to use. Just scoop, stir and go.

It’s effective any time of day, whether you take it before or after a workout. Collagen promotes recovery because it’s the main protein your body recruits to help build everything from the connective tissue in skin to the tendons that attach muscles to bone.

Unfortunately, there’s a lot of variability with collagen products. Some companies use fillers or artificial colors (we don’t). And although you can get the same amino acid benefits from collagen capsules, you want to investigate what the capsules are made of, how much collagen you get per serving and what the ingredients are.

Collagen protein powder is simple — and there’s no need to carry around a fistful of collagen capsules. Bulletproof Collagen Protein is 100% hydrolyzed collagen protein and nothing else. Plus, collagen powder is easy to use. Just add 1-2 scoops to whatever you’re drinking right now. Done.

Yes! Collagen adds a punch of protein and blends beautifully into Bulletproof Coffee.

Pretty much anything. Collagen is really easy to add to your favorite recipes because it’s heat-stable, which means you can add it to hot drinks or even bake with it. Start by mixing it into your morning coffee or tea. Whip up a batch of Double Chocolate Chip Keto Cookies. Prep some Easy Keto White Truffles.

Because we believe that you deserve the best product possible. Our collagen comes from pastured cows that spend most of their lives roaming outside and grazing exclusively on grass, as nature intended. That means no hormones, no GMOs, no antibiotics — and no traces of junk in your collagen.

Yes. Bulletproof Collagen Protein contain zero carbs, so it won’t kick you out of ketosis.

Our collagen protein powders contain no added sugar*. Our flavored collagen protein powders contain ingredients we believe in, like raw cacao powder and erythritol — a sugar alcohol that won’t affect your blood sugar. Besides, we don’t need to add any sugar*. The benefits of collagen are sweet enough on their own.

*Not a low-calorie food.
