Does Bone Broth Have Collagen? (And How Much Per Cup)
Jump to a section
Yes, bone broth has collagen. A well-made cup typically delivers 6 to 12 grams, with beef broth on the higher end at 8 to 11 grams and chicken broth around 6 to 9 grams. The exact amount depends on the bones you choose, how long you simmer, and whether you use acid.
That is the short answer. The longer one matters because the gap between a thin stockpot and a properly gelled batch comes down to choices you make at the start.
How much collagen is in a cup of bone broth?
The honest range is 6 to 12 grams per cup of well-made bone broth. ConsumerLab tested 10 commercial bone broths in April 2025 and found collagen content ranging from 1 to 6 grams per cup, with only 6 of the 10 products meeting their approval threshold. Bare Bones publishes 10 grams of protein and 5 grams of collagen per cup on their liquid Classic Bone Broth. The number on the label and the number that ends up in the cup are not always the same.
The biggest factor is the protein: beef broth runs 8 to 11 grams per cup and is mostly Type I and Type III collagen, which are the structural proteins in skin, bone, and connective tissue. Chicken broth runs 6 to 9 grams per cup and is exceptionally rich in Type II collagen, the kind concentrated in cartilage and joints. Duck and pork contain a similar 6 to 9 grams per cup as chicken.
Research has also pushed back on the food-as-medicine framing. A 2019 study in the International Journal of Sport Nutrition and Exercise Metabolism found that bone broth often does not deliver reliable concentrations of the specific amino acids supplements are designed to provide. The takeaway is not that bone broth is empty. The takeaway is that the variability is real, and it tracks the way you make the broth more than the fact that it's bone broth.
Why bone broth contains collagen
The cold gel is the at-home test. Pour a cup of finished broth into a glass, refrigerate overnight, and look at it the next morning. If it jiggles like loose Jello, you extracted gelatin. If it stays liquid, you need more time, more bones, or acid next batch.
The gel is the proof.
Once you eat the broth, your digestion breaks gelatin back down into its amino acids. The three that matter most are glycine, proline, and hydroxyproline. Your body reassembles those amino acids into new collagen in your own connective tissue, which is the actual mechanism behind how that collagen helps joints and skin. Bones to broth to gelatin to amino acids to your own collagen. Slow, but real.
What affects how much collagen ends up in your cup
Bones
The cut matters more than anything else. Knuckle bones, oxtail, knee joints, and chicken feet are the highest-collagen cuts. Lean meat bones contribute flavor but very little gelatin. Marrow bones add richness and fat but contribute less structural collagen than the joint-heavy cuts, so a pot built around marrow alone will not gel as firmly as one built around knuckles. A pot of clean meat bones will produce a light, thin broth with little body, no matter how long you simmer it.
If you are sourcing bones, ask the butcher specifically for joint and connective bones, not just "soup bones." Our best beef bones for bone broth post goes deeper on which cuts to ask for and why. Making chicken broth instead? Our best chicken bones for bone broth guide covers the poultry cuts worth asking for.
Simmer time
Bone broth needs hours. Beef bones extract well over 12 to 24 hours at low heat. Chicken bones extract faster, around 6 to 12 hours, because the bones are smaller and softer. Under 4 hours is barely a stock. Past 24 hours, gains plateau and some sources note that gelatin can start breaking down past the 16 to 18 hour mark.
The temperature matters too. Hold the broth at a low simmer, around 180 to 200°F. Visually that's a few small bubbles breaking the surface every second or so, not a rolling boil. A hard boil emulsifies the fat and clouds the broth without adding collagen. A gentle, almost-still simmer for many hours is the move. This is why slow cookers and stockpots over a low burner work so well.
Acid
A small amount of acid lowers the pH of the simmering water, which helps break down the bone matrix and free up more collagen. One to two tablespoons of apple cider vinegar or lemon juice per gallon of water, added at the start, is the standard ratio. You will not taste it in the finished broth.
Bone broth vs collagen supplements: which delivers more?
On raw concentration, collagen powders win. A scoop of hydrolyzed collagen typically delivers 10 to 20 grams of collagen protein, often double what a cup of bone broth provides. If you are chasing a specific dose for a specific reason, the powder is more efficient and more measurable.
On bioavailability, the difference is smaller than supplement marketing suggests. Both bone broth gelatin and collagen powders are pre-broken-down forms that your gut absorbs as amino acids. Your body does not particularly care which form delivered them.
On cost per gram of collagen, supplements also win. A daily scoop runs cheaper than a daily cup of homemade broth.
Bone broth wins on everything else. Flavor. Cooking versatility. Mineral content. Nourishment that doubles as the base for risotto, pan sauces, soups, and braises. And nobody ever said "I wish my supplement also tasted like a slow-simmered pot of beef bones."
You can take both. They do not interact. Bone broth is food, collagen powder is a supplement, and the question of which is "better" depends on what you are trying to do.
How to maximize collagen in your bone broth
If you want a batch that gels like a panna cotta when chilled, do all of this:
- Build the pot around joint-heavy bones. Knuckles, feet, oxtail, marrow bones with the joints attached. For our 100% grass-fed beef sourcing, the knuckle and shank cuts gel hardest.
- Roast the bones first at 400°F for 30 to 40 minutes. This is for flavor and color, not collagen, but it is worth doing.
- Cover with cold water by 2 inches. Add 1 to 2 tablespoons of apple cider vinegar per gallon.
- Bring to a low simmer, then hold at 180 to 200°F for 12 to 24 hours for beef, or 6 to 12 hours for chicken. Skim the foam in the first hour. After that, leave it alone.
- Strain, cool to room temperature, then refrigerate overnight. The next morning, check for the cold gel.
Once you have the gel, the broth is its own ingredient. We use it everywhere. Our cooking with bone broth post breaks down the everyday uses, from grain liquid to braising base to the secret behind a glossier pan sauce.
The Cook's Take
Yes, bone broth has collagen, and a realistic range is 6 to 12 grams per cup. The science backs it. The variation is real. And every lever that matters is in your control: the bones, the simmer, the acid. Get those right and the cold gel proves it.
Our beef demi-glace and bone broths start with 100% grass-fed bones from pasture-raised cattle, slow-simmered in small batches with no shortcuts. One ingredient, real reduction, the kind of body that comes from hours and not from gums or starches. That is what we make, and a properly gelled cup is what it looks like.

Common questions
Which beef bones have the most collagen?
Knuckle bones, oxtail, and knee joints are the highest-collagen cuts. Lean meat bones contribute flavor but very little gelatin, and marrow bones add richness and fat but less structural collagen. For a collagen-maximized broth, build the pot around joint-heavy cuts and add a few marrow bones for richness.
How long should you simmer bone broth for collagen?
12 to 24 hours for beef, 6 to 12 hours for chicken. Under 4 hours yields weak extraction. Past 24 hours, gains plateau. Hold the temperature at a low simmer of 180 to 200°F. A hard boil clouds the broth without adding collagen.
Does bone broth have as much collagen as collagen supplements?
No. A scoop of collagen powder delivers 10 to 20 grams of collagen, often double a typical cup of bone broth. Bone broth wins on bioavailability, flavor, and cooking versatility. Powder wins on raw concentration and cost per gram.
Does store-bought bone broth have collagen?
Sometimes a lot, sometimes very little. Wide variation across brands. Look for products that gel firmly when refrigerated and list a measurable protein content per serving. Diluted, short-simmered, or shelf-stable broths often contain very little collagen even when labeled "bone broth."
Is bone broth or stock higher in collagen?
Bone broth, by design. Stock simmers shorter and uses fewer bones. Bone broth is the long-simmer, bone-heavy version that extracts more collagen. The terminology is loose, but simmer time is the reliable signal: under 4 hours is stock, 12 hours and up is bone broth.
