Understanding Collagen in Chicken
Collagen is a key protein that provides structure to the body's connective tissues, including skin, bones, and ligaments. Dietary collagen sources are often sought after because collagen production decreases with age. When considering which part of chicken is high in collagen, the focus should be on areas rich in connective tissue and cartilage, not solely the muscle meat.
Chicken Parts High in Collagen
While all parts of a chicken contain some collagen, certain parts are superior due to higher concentrations of connective tissue.
Chicken Feet: The Most Concentrated Source
Chicken feet are arguably the most concentrated source of collagen in a chicken. The feet are almost entirely composed of bone, tendons, skin, and cartilage, all of which are rich in Type II collagen. Research shows that approximately 70% of the protein in chicken feet is collagen. Slow cooking is the best method to extract this protein.
Chicken Skin
Chicken skin contains significant amounts of collagen, whether it's from the wings, thighs, or breasts. The skin can be around 35% connective tissue, mainly collagen. Moderate consumption of chicken skin can boost collagen intake, especially when used in bone broth. Some studies suggest collagen peptides derived from chicken skin may have anti-cancer properties.
Wings, Necks, and Backs
These parts are ideal for bone broth because they have a high ratio of bone and cartilage to meat. The small bones and joints in wings, along with the connective tissue in backs and necks, are perfect for slow simmering to release nutrients and collagen.
Dark Meat (Thighs and Legs)
Dark meat from chicken thighs and legs has a greater collagen content than white breast meat. This is because the muscles in these areas are more active and require more connective tissue for support. Consuming bone-in, skin-on thighs is a good way to increase collagen intake, compared to breast meat.
Bone Broth: Maximizing Collagen Extraction
Bone broth is one of the most effective methods to extract the most collagen from chicken parts. The slow-simmering process breaks down collagen into gelatin, which the body can absorb more easily.
Making Collagen-Rich Chicken Bone Broth:
- Select the right parts: Use chicken feet, backs, necks, wings, and carcasses for the best broth.
- Add aromatics: Include vegetables like onions, carrots, and celery, along with herbs such as thyme or rosemary for added flavor.
- Add apple cider vinegar: Add a splash of apple cider vinegar. This helps to extract the collagen and minerals from the bones during cooking.
- Simmer for a long time: Cook over low heat for at least 8-12 hours, or longer. A pressure cooker can reduce the cooking time.
- Cool and strain: After simmering, strain out the solids. A gelatinous consistency after refrigeration indicates high collagen content.
Collagen Content Comparison by Chicken Part
| Chicken Part | Primary Collagen Source | Collagen Content | Best For... |
|---|---|---|---|
| Chicken Feet | Skin, Bones, Cartilage | Highest | Broth, gelatin, joint support |
| Chicken Skin | Connective Tissue | High | Broth, crispy snacks |
| Thighs (Dark Meat) | Connective tissue | Moderate | Regular meals, stews |
| Breast (White Meat) | Muscle Tissue | Low | General protein intake |
Chicken Collagen vs. Other Animal Sources
It's important to differentiate chicken collagen from other animal sources. Chicken collagen is primarily Type II, which is beneficial for joint and tendon health. Beef collagen is rich in Type I and III, which are concentrated in skin and bones, and are highly regarded for skin elasticity and bone strength. Marine collagen (from fish) is primarily Type I, which benefits skin, hair, and nails. Choosing the right source depends on your specific health goals.
Conclusion: Best Parts for Collagen
To maximize collagen intake, prioritize chicken feet, skin, wings, and other parts rich in connective tissue. Bone-in, skin-on thighs and legs are also good sources. The most effective method to extract this protein is through long, slow simmering to create bone broth. Combining these parts with other collagen-supporting nutrients like Vitamin C, zinc, and copper can effectively enhance your body's natural collagen production.

Best Practices for Consuming Chicken Collagen
- Prioritize Bone Broth: Use feet and carcasses to make a rich batch of bone broth, a great source of collagen and minerals.
- Don't Discard the Skin: Cook chicken with the skin on and consume it in moderation as part of a balanced diet.
- Include Dark Meat: Choose chicken thighs and legs, as they naturally contain more connective tissue than breast meat.
- Combine with Vitamin C: Pair your collagen-rich meals with foods high in Vitamin C to aid synthesis.
- Focus on Consistency: Regular consumption of collagen-rich chicken is more effective for overall health than occasional high doses.
The Role of Chicken Collagen in Joint Health
Type II collagen found in chicken has been shown to support joint health. It may help reduce joint pain and stiffness in people with osteoarthritis. Regular consumption can promote better joint mobility and comfort by providing the building blocks and compounds such as glucosamine and chondroitin.
Chicken Collagen and Skin Health
Beyond joints, chicken collagen also contributes to skin health, improving elasticity and hydration. The Type II collagen in chicken offers benefits for a more hydrated complexion.
