Introduction
Whether you are finishing a long trail run, hitting a new personal best on the squat rack, or simply moving through a busy day, your joints carry the load. You might notice a bit of stiffness in your knees or a nagging ache in your shoulders that wasn't there a few years ago. Often, this comes down to the health of your cartilage—the flexible, slippery tissue that cushions your bones. This cartilage is primarily made of type 2 collagen, a specialized protein that acts as a natural shock absorber.
While many people are familiar with collagen for skin and hair, those benefits usually come from types 1 and 3. Type 2 is different; it is specifically designed to support joint mobility and structural integrity. At BUBS Naturals, we believe that understanding what you put into your body is the first step toward better performance and recovery. In this guide, we will break down exactly which foods contain type 2 collagen, how your body uses them, and why this specific protein is vital for an active lifestyle.
Our goal is to help you navigate the often-confusing world of nutrition with clear, actionable information. By the end of this article, you will know how to adjust your diet to better support your joints and keep you moving toward your next adventure.
Quick Answer: The primary food sources of type 2 collagen are chicken cartilage, chicken sternum, and bone broth made specifically from chicken. Unlike types 1 and 3, which are found in beef and fish, type 2 is almost exclusively found in the connective tissues of poultry.
Understanding Type 2 Collagen
To understand which foods to eat, we first need to look at what type 2 collagen actually is. Collagen is the most abundant protein in the human body, but it isn't a single substance. There are at least 28 different types, though types 1, 2, and 3 make up about 80–90% of the total.
Type 2 collagen is the major structural component of hyaline cartilage. This is the specific type of cartilage that lines your joints. If you think of your joints like a mechanical hinge, the type 2 collagen is the smooth coating that prevents the metal parts from grinding together. It is composed of three long chains of amino acids coiled into a tight triple helix. This structure gives it incredible tensile strength, allowing it to withstand the pressure of your body weight and the impact of movement.
When we talk about joint "wear and tear," we are often talking about the gradual breakdown of this type 2 collagen matrix. As we age, our body’s natural production of collagen slows down. For athletes and active adults, this can lead to decreased mobility and increased discomfort. By focusing on foods that provide the specific building blocks for type 2 collagen, you can help support your body’s ability to maintain and repair this essential tissue.
How It Differs from Other Types
Most collagen supplements and food sources—like bovine hide or fish scales—are rich in types 1 and 3. These are excellent for supporting the elasticity of your skin, the strength of your nails, and the density of your bones. However, they do not contain the specific molecular structure required to build joint cartilage.
Type 2 collagen is unique because it often contains naturally occurring glucosamine and chondroitin. You may recognize these names from the joint health aisle at the vitamin shop. These compounds work alongside the collagen fibers to help the cartilage retain water, which is what gives it that "spongy," shock-absorbing quality.
Collagen Peptides
Top Foods That Contain Type 2 Collagen
Finding type 2 collagen in whole foods is more challenging than finding types 1 and 3. This is because we typically don't eat the parts of the animal where type 2 is most concentrated. While you can find type 1 in a steak or a piece of salmon, type 2 is tucked away in the "gristle" and bones.
Chicken Cartilage and Sternum
The single best source of type 2 collagen in the animal kingdom is chicken cartilage, particularly from the sternum (the breastbone). If you have ever roasted a whole chicken and noticed the soft, white, rubbery bits at the end of the bones, that is type 2 collagen in its purest food form.
Historically, humans consumed much more of these "odd bits," but modern diets tend to favor lean muscle meats like chicken breasts or thighs, which contain almost no collagen. To get the benefits from whole food, you would need to consume the connective tissues themselves. While not common in Western cooking, some cultures incorporate chicken feet or soft bone tissues into stews and soups specifically for their health benefits.
Chicken-Based Bone Broth
If eating cartilage directly doesn't sound appealing, bone broth is the most practical alternative. However, there is a catch: not all bone broth is created equal. If your goal is specifically joint support through type 2 collagen, you must choose chicken-based broth rather than beef.
Beef bone broth is fantastic for gut health and skin because it is loaded with type 1 collagen. But because chicken carcasses (especially the necks, backs, and feet) are so much richer in cartilage, the resulting broth is much higher in type 2. When you simmer these parts for 12 to 24 hours, the collagen undergoes a process called denaturation. This breaks the tough fibers down into gelatin, which is much easier for your digestive system to handle.
Key Takeaway: For joint-specific recovery, prioritize chicken bone broth made with the "ends" of the bones and connective tissues, as this contains the specific type 2 fibers not found in beef or fish.
Animal Connective Tissues (Beef and Pork)
While chicken is the king of type 2, it can also be found in the cartilage of other animals, such as cows and pigs. In these animals, type 2 is located in the joints and the trachea. In some traditional cuisines, dishes like tripe, beef tendon, or slow-cooked pork hocks are prized for their high collagen content. When these tissues are slow-cooked over low heat, the tough connective fibers melt into a rich, gelatinous texture. This provides the amino acids—specifically proline, glycine, and hydroxyproline—that your body needs to synthesize its own joint cartilage.
Organ Meats
Organ meats are often overlooked in the modern diet, but they are nutritional powerhouses. While the muscle of an organ (like the heart) is high in protein, the surrounding connective membranes can contain various types of collagen. While not as concentrated as chicken sternum, incorporating a variety of organ meats can provide a broader spectrum of the nutrients required for collagen synthesis, such as copper and vitamin A.
Comparing Collagen Sources
Because the different types of collagen serve such different purposes, it is helpful to see how they stack up. Using the right tool for the job is essential in training, and the same applies to your nutrition.
| Collagen Type | Primary Locations in Body | Best Food Sources | Main Benefit |
|---|---|---|---|
| Type 1 | Skin, tendons, bone, organs | Beef, fish, egg whites | Skin elasticity & bone strength |
| Type 2 | Hyaline cartilage (joints) | Chicken cartilage, chicken bone broth | Joint mobility & cushioning |
| Type 3 | Muscles, arteries, skin | Beef, pork, poultry | Gut health & skin structure |

Join The ClubWhy Type 2 Is Hard to Get from Food Alone
Even if you are committed to a "nose-to-tail" diet, getting an effective amount of type 2 collagen from food can be difficult. There are two main reasons for this: availability and bioavailability.
The Availability Problem
Most people do not enjoy eating raw cartilage or gristle. Even when we cook a whole chicken, we often discard the very parts—the bones and the connective tissue—that contain the type 2 collagen. To get a therapeutic dose, you would need to consume large quantities of chicken-based bone broth or specific animal parts daily.
The Bioavailability Problem
Bioavailability refers to how well your body can absorb and use a nutrient. Collagen in its raw food form is a very large, complex protein. Your digestive system has to work hard to break it down into individual amino acids. If your digestion isn't optimal, you might only absorb a fraction of what you eat.
This is why many people turn to hydrolyzed collagen peptides. Hydrolysis is a process where the protein chains are broken down into smaller "peptides" using enzymes. These peptides are much easier for your body to absorb and can be shuttled directly to where they are needed most. At BUBS Naturals, our products are designed to be highly bioavailable, ensuring that the work you put into your nutrition actually pays off in your recovery.
Myth: Eating collagen will immediately turn into collagen in your joints.
Fact: When you eat collagen, your body breaks it down into amino acids. However, type 2 collagen also contains "signaling" molecules that may tell your body to increase its own natural production of joint cartilage.
Nutrients That Support Collagen Production
Eating the right foods is only half the battle. Your body is like a construction site; even if you have all the lumber (the amino acids), you still need the workers and the tools to build the house. Several key nutrients act as "co-factors" that help your body turn food into functional joint tissue.
Vitamin C
Vitamin C is the most critical co-worker for collagen. Without it, your body literally cannot form the triple helix structure of the collagen molecule. This is why a deficiency in Vitamin C (scurvy) leads to joint pain and skin problems—the body's "glue" is falling apart.
To support your type 2 collagen intake, you should pair it with Vitamin C-rich foods like citrus fruits, bell peppers, or strawberries. We offer a Vitamin C supplement specifically designed to support this process, providing 500 mg alongside citrus bioflavonoids to maximize absorption.
Zinc and Copper
These minerals act as catalysts in the collagen synthesis process. Zinc is essential for cell repair and the production of protein, while copper helps activate the enzyme that links collagen and elastin fibers together. You can find these in pumpkin seeds, oysters, lentils, and dark chocolate.
Apple Cider Vinegar
While apple cider vinegar (ACV) doesn't contain collagen, it can help the process. The acetic acid in ACV can support healthy digestion and stomach acid levels. Proper stomach acid is necessary to break down the tough proteins found in collagen-rich foods like bone broth. If you aren't a fan of the liquid taste, our Apple Cider Vinegar Gummies are a simple way to incorporate this into your routine.
Real-World Benefits for the Active Adult
Why should you go through the trouble of sourcing chicken cartilage or simmering bones for 24 hours? For the active adult, the benefits of supporting type 2 collagen levels are practical and tangible.
Improved Recovery Times
When you train hard, you create micro-trauma in your connective tissues. This is a normal part of getting stronger, but it requires raw materials to repair. Providing your body with the specific amino acids found in type 2 collagen can help your joints bounce back faster after a heavy lifting session or a long day on the trail.
Maintaining Mobility
As we get older, our joints can feel "sticky" or stiff, especially in the morning. This is often because the synovial fluid (the joint's lubricant) and the cartilage are thinning. Maintaining a diet rich in collagen-supporting foods can help preserve that "glide" in your joints, making daily movements feel more fluid and less like a chore.
Long-Term Joint Integrity
Health isn't just about how you feel today; it’s about how you’ll move ten or twenty years from now. By consistently providing your body with type 2 collagen precursors, you are essentially performing preventative maintenance on your internal "machinery." It is much easier to support healthy cartilage now than it is to try and rebuild it later.
Note: Consistency is key. You wouldn't expect to see results from a single workout, and the same applies to your nutrition. Supporting your joints is a long-term play that requires a daily commitment to clean, functional ingredients.
Practical Ways to Add Type 2 Collagen to Your Diet
If you want to start today, here are some actionable steps to increase your intake of type 2 collagen and its supporting nutrients:
- Make "Joint Health" Soup: The next time you roast a chicken, don't throw the carcass away. Put it in a slow cooker with water, a splash of apple cider vinegar, and some salt. Let it go for 24 hours. Drink a mug of this broth every morning.
- Eat the "Ends" of the Bone: If you are eating chicken wings or drumsticks, notice the soft, white cartilage at the ends of the bone. While you don't have to eat the hard bone itself, consuming that soft connective tissue provides a direct hit of type 2 collagen.
- Rotate Your Proteins: Don't just stick to lean fillets. Incorporate cuts of meat that have more connective tissue, like slow-cooked pot roasts or braised chicken thighs.
- Supplement Strategically: Because food sources of type 2 are so limited, a high-quality supplement can bridge the gap. Look for products that are third-party tested and NSF for Sport certified, especially if you are a competitive athlete or veteran who needs to trust every ingredient.
How Type 2 Fits into a Wellness Routine
At the end of the day, nutrition is one piece of the puzzle. Supporting your joints with type 2 collagen works best when paired with other healthy habits. Proper hydration is essential, as cartilage is about 60% to 80% water. If you are dehydrated, your "shock absorbers" won't work as effectively. Our Hydrate or Die electrolytes can help ensure that the water you drink actually reaches your cells and your joints.
Similarly, movement is medicine. Cartilage doesn't have its own blood supply; it relies on the "pumping" action of movement to bring nutrients in and waste products out. Eating a collagen-rich diet and then staying sedentary won't yield the same results as pairing that nutrition with regular, low-impact exercise like walking, swimming, or cycling.
Bottom line: Type 2 collagen is the foundation of joint health, found almost exclusively in poultry cartilage and bone broth. To see real results, pair these food sources with Vitamin C and consistent movement.

FAQ
Does beef collagen contain type 2?
Most beef collagen, which comes from bovine hides, is rich in types 1 and 3, which are great for skin and bones. To get type 2 collagen from a bovine source, it must specifically come from the cartilage or trachea of the cow, though chicken remains the most common and concentrated source.
Can I get type 2 collagen from plant-based foods?
No, collagen of any type is only found in animal products. While plants do not contain collagen, you can support your body's natural production by eating foods high in Vitamin C, zinc, and copper, such as citrus fruits, leafy greens, seeds, and nuts.
How is type 2 collagen different from glucosamine?
Type 2 collagen is the actual protein fiber that makes up the structure of the cartilage. Glucosamine and chondroitin are "muco-polysaccharides" that live within that collagen matrix to help it hold water. They often appear together in food sources like chicken sternum because they work as a team to support joint health.
How much type 2 collagen do I need daily?
While there is no official daily recommended intake, many studies focused on joint comfort use amounts ranging from 10mg to 40mg of undenatured type 2 collagen or several grams of hydrolyzed collagen. For most active adults, a daily serving of bone broth or a high-quality supplement is a practical way to ensure consistent intake.
