What Foods Have Collagen? The Best Dietary Sources
by Dr. Kellyann
The best natural collagen sources are all animal-derived, and the highest concentrations come from parts of animals most modern diets rarely include. Bone broth (made from long-simmered bones and connective tissue) is the single most practical whole-food collagen source. Skin-on chicken, pork skin, fish with skin, tough cuts of meat cooked slowly on the bone, and organ meats all contribute meaningful collagen when included regularly. Plant foods do not contain collagen (which is technically an animal protein), but certain plants provide the vitamins and minerals your body uses to synthesize its own collagen.
For most women, the practical answer is to combine one or two whole-food collagen sources (particularly bone broth) with a daily Collagen Peptides Unflavored supplement for concentrated intake. Let me walk you through the specific foods and how to build meaningful daily collagen through diet.
The Best Whole-Food Collagen Sources
Bone Broth
Bone broth is the single most practical natural collagen source for daily use. The long simmer time (24 hours or more) breaks down the collagen in bones and connective tissue into gelatin, which delivers meaningful glycine, proline, and hydroxyproline in a highly digestible form. A cup of quality bone broth like my Bone Broth Classic Chicken delivers roughly 9 grams of collagen-derived protein along with the minerals your body may use for collagen synthesis.
Skin-On Chicken
The skin of chicken (particularly when prepared with the connective tissue attached, like roasted whole chickens or chicken feet in stocks) is one of the most concentrated natural collagen sources. Modern diets that only include skinless chicken breast miss most of the collagen chicken can provide. Roasting whole chickens and using the carcass for broth captures the collagen in ways that boneless skinless breast cannot.
Tough Cuts Cooked Slowly on the Bone
Braised short ribs, oxtail, lamb shanks, pork shoulder, chuck roast, and other tough cuts contain meaningful collagen in their connective tissue. Slow cooking breaks down that collagen into gelatin, which is why these cuts turn tender and often gel when the cooking liquid is cooled.
Fish With Skin
The skin of fish (particularly wild salmon, mackerel, and sardines) contains marine collagen along with omega-3 fats. Eating fish with the skin on is one of the more practical ways to include marine collagen in a modern diet.
Organ Meats
Liver, kidney, and other organ meats provide collagen along with concentrated nutrients rare in muscle meat. Traditional culinary cultures worldwide have historically valued organ meats specifically for these nutrient profiles, though modern American diets have moved away from them.
Gelatin
Powdered gelatin (the same product used to make homemade gummies, panna cotta, or Jello) is essentially concentrated collagen. Used in cooking or as a supplement mixed into hot liquids, gelatin provides the same amino acid profile as bone broth in a more shelf-stable form.
Foods That Support Your Body's Own Collagen Production
Plants do not contain collagen (it is an animal-only protein), but certain plant foods provide the specific nutrients your body may use to synthesize its own collagen. These support your collagen production even without directly delivering collagen.
Vitamin C-Rich Foods
Vitamin C is essential for collagen synthesis. Without adequate vitamin C, your body cannot properly assemble collagen, which is why severe vitamin C deficiency historically caused scurvy (a disease of collagen breakdown). Bell peppers, citrus fruits, strawberries, broccoli, kiwi, and dark leafy greens all provide meaningful vitamin C. The Harvard T.H. Chan School of Public Health Nutrition Source has covered vitamin C's role in tissue synthesis in more depth.
Zinc-Rich Foods
Zinc is another cofactor for collagen synthesis. Oysters, red meat, poultry, pumpkin seeds, and chickpeas are strong sources. Zinc deficiency compromises collagen production even when adequate amino acids are available.
Copper-Containing Foods
Copper plays a role in the cross-linking of collagen fibers that makes collagen structurally sound. Liver, dark chocolate, cashews, sesame seeds, and shiitake mushrooms provide dietary copper.
Sulfur-Rich Foods
Garlic, onions, cruciferous vegetables (broccoli, cauliflower, Brussels sprouts), and eggs provide sulfur, which supports collagen stability.
The Practical Daily Collagen Approach
For most women, meaningful daily collagen intake through diet alone requires either consistent bone broth practice (two to three cups per day) or regular inclusion of skin-on proteins, tough cuts cooked slowly, and organ meats. Because that pattern is impractical for most modern lifestyles, a quality collagen supplement fills the gap efficiently.
The rhythm I recommend to most women: daily bone broth (two to three cups) for the whole-food collagen and mineral support, plus 10 to 20 grams of collagen peptides for concentrated daily intake, plus regular inclusion of vitamin C-rich foods to support your body's own collagen synthesis. My Collagen Peptides Unflavored or premium Liquid Gold both provide the concentrated collagen intake, and the full Bone Broth collection makes daily bone broth practice practical.
What Foods Do NOT Have Collagen
A few common misconceptions worth clearing up. No plant food contains collagen. Marketing that describes plant-based collagen boosters or vegan collagen sources refers to plants that provide amino acid precursors or vitamin C, not actual collagen. Muscle meat alone (chicken breast, sirloin steak without connective tissue) contains protein but very little collagen; the collagen is in the skin, bones, and connective tissue that most modern American diets remove. Regular chicken stock or beef stock made in 2 to 4 hours contains meaningfully less collagen than bone broth made in 24 hours or more. The long simmer time is what breaks down the collagen and delivers it into the liquid.
Building Daily Collagen Into Modern Eating
The practical approach for modern women is to combine daily bone broth as the whole-food anchor with a concentrated collagen supplement for daily consistency. My Bone Broth Classic Chicken and my Collagen Peptides Unflavored form the daily foundation for most women I have worked with. For a fuller comparison of collagen versus collagen peptides specifically, my post on collagen vs collagen peptides walks through the format differences in depth. And for a broader nutritional framework that integrates daily collagen support, the Bone Broth Diet 21-day program provides structure.
Frequently Asked Questions
What foods are highest in collagen?
Bone broth is the most practical whole-food collagen source, delivering around 9 grams of collagen-derived protein per cup. Other high-collagen foods include skin-on chicken, tough cuts of meat cooked slowly on the bone (short ribs, oxtail, lamb shanks), fish with skin (particularly salmon), organ meats, and gelatin. Plant foods do not contain collagen; only animal-derived foods do.
Do any plant foods contain collagen?
No plant food contains collagen because collagen is an animal-only protein. Products marketed as vegan collagen or plant-based collagen boosters actually contain amino acid precursors and vitamin C-rich compounds that support your body's own collagen synthesis rather than replacing collagen intake directly. For dietary collagen, animal-derived sources like bone broth, skin-on proteins, and collagen peptide supplements are the only true options.
How can I get more collagen naturally through food?
Include bone broth two to three times per day (the most practical daily source), eat skin-on chicken and fish regularly, choose tough cuts of meat cooked slowly on the bone (short ribs, oxtail, chuck roast), include organ meats occasionally, and support your body's own collagen synthesis with vitamin C-rich foods (bell peppers, citrus, berries, dark leafy greens), zinc, and copper. Most modern diets need supplementation with collagen peptides to reach meaningful daily intake.
Is bone broth the best source of collagen?
Bone broth is the most practical whole-food source of collagen for daily use because it delivers meaningful collagen-derived amino acids (roughly 9 grams per cup) in a highly digestible form alongside minerals and electrolytes. It cannot match the concentration of a collagen peptide supplement (10 to 20 grams per scoop), but it provides broader nutritional support that a supplement cannot. Most women benefit from including both in daily practice.
