Bone Broth and Connective Tissues: The Ultimate Collagen Source
While steak and chicken breast contain some collagen, the highest concentrations are found in the parts of the animal that most people discard: the bones, skin, and connective tissues. The most efficient way to maximize collagen intake from meat is by consuming bone broth, a rich liquid made by simmering animal bones for extended periods. This slow cooking process breaks down the tough, fibrous collagen into a more digestible, gelatinous form. The specific animal source matters, as different animals provide different types of collagen with varying benefits.
Beef: Rich in Type I and III Collagen
Beef is a powerful source of both Type I and Type III collagen, making it particularly beneficial for skin, bone, and gut health. The densest and highest collagen content is found in the toughest, slow-cooked cuts. For example, beef tendons have a remarkably high collagen content, with studies showing as much as 13.3 grams per serving. Similarly, cuts that require long simmering, such as oxtail, brisket, and shank, are loaded with collagen-rich connective tissues that turn tender and gelatinous during cooking. A flavorful, collagen-rich beef bone broth can be made by simmering roasted beef marrow bones with vegetables and herbs for many hours. The resulting liquid contains a rich, concentrated supply of collagen and essential minerals.
Best Beef Parts for Collagen
- Oxtail: Known for its tough, bone-in structure, it requires long, slow cooking to release a high amount of gelatinous collagen.
- Brisket: This cut's high concentration of connective tissue makes it perfect for slow-cooking methods that break down collagen and make the meat tender.
- Shank: Beef shank is rich in connective tissue and bones, offering a high-density source of collagen that is released during long cooking times.
- Beef Tendon: For the truly dedicated, beef tendon is one of the single richest sources, containing extremely high percentages of pure collagen protein.
Pork: A High-Yield Source, Especially from Skin
Like beef, pork offers significant collagen, particularly from its skin and tougher cuts. Pork skin is an exceptionally high-yield source. When boiled and then fried to create pork rinds, the collagen content is substantial. Pork hocks and legs are another excellent option, as they are dense with joints and connective tissues. Jellied pork dishes, or aspic, highlight this collagen-rich quality by solidifying the broth into a gelatinous, nutrient-dense meal.
High-Collagen Pork Options
- Pork Skin and Rinds: Extremely high in collagen, pork skin and its fried form, pork rinds, provide a dense, pure source of collagen.
- Pork Hocks and Legs: These parts, including the bones, skin, and tendons, are ideal for simmering to create a rich, collagen-infused stock or stew.
- Pork Belly: While prized for its fat, pork belly also contains significant collagen in the layers of skin and connective tissue, which break down during cooking.
Poultry: A Source of Type II Collagen
Chicken and turkey are also good sources of collagen, though they typically contain less per weight than tough beef or pork cuts. However, poultry is especially rich in Type II collagen, which is critical for joint and cartilage health. The most concentrated sources are found in the skin, feet, and keel bone cartilage. Chicken feet, for instance, are widely used in Asian cuisine and stews precisely for their ability to produce a gelatinous, collagen-rich stock. Chicken skin is also a great option, providing a significant amount of collagen per serving.
High-Collagen Poultry Parts
- Chicken Feet: Often overlooked, chicken feet are a powerhouse of Type II collagen for joint health when simmered into a broth.
- Chicken Skin: Whether consumed with the meat or rendered separately, chicken skin is a potent source of collagen.
- Keel Bone Cartilage: A potent source of Type II collagen, keel bone cartilage is highly concentrated in collagen protein.
- Bone-in Cuts: Wings, thighs, and other cuts with bones still attached offer more collagen than boneless, skinless options.

| Ideal Cooking Method | Long, slow simmering or braising | Slow cooking for gelatin release | Simmering for bone broth or eating skin |
| Associated Benefit | Skin elasticity, gut health, joint support | Skin firmness, joint support | Cartilage and joint health |
Cooking Methods to Maximize Collagen
To effectively extract and utilize collagen from meat, the cooking method is paramount. Collagen is a tough, fibrous protein that requires heat and moisture to break down into gelatin. This is why slow-cooking techniques are so effective. Braising tough cuts of beef like brisket or simmering a whole chicken for bone broth allows the connective tissues to melt and enrich the cooking liquid. The resulting broth, rich with gelatin, will thicken when cooled, a tell-tale sign of high collagen content. Incorporating collagen-rich parts into stews, soups, and stocks is an excellent way to boost your intake without needing supplements.
Conclusion: The Toughest Cuts Are The Richest
The highest collagen content in meat is consistently found in the often-overlooked parts of the animal—the skin, bones, and toughest connective tissues. While beef, pork, and chicken all offer valuable forms of collagen, focusing on cuts like oxtail, pork skin, and chicken feet, and utilizing slow-cooking methods like making bone broth, will yield the greatest nutritional benefit. By embracing these nose-to-tail eating practices, you can effectively enhance your diet with natural, bioavailable collagen to support healthy skin, joints, and overall vitality. Choosing nutrient-dense, real-food sources is a more reliable approach than relying on unregulated supplements alone.
