12 Collagen-Rich Foods for Healthier, Radiant Skin
This selection nourishes your complexion and helps maintain fluid, comfortable movement.
Collagen is the most abundant protein in the human body and essential for maintaining the strength, elasticity, and youthful appearance of skin, as well as the overall health of joints, hair, and nails. While collagen supplements have soared in popularity, the most sustainable and holistic way to enhance your body’s collagen is by incorporating nutrient-dense, whole foods that naturally support collagen synthesis and structure.
This guide covers the top 12 collagen-rich foods and explains how each supports your body’s collagen production for glowing, radiant skin and optimal health.
What Is Collagen?
Collagen is a structural protein that forms the connective tissue in skin, tendons, ligaments, and bones. It works as the scaffolding that keeps skin firm and plump, supports joint movement, and contributes to wound healing. As we age, our bodies naturally produce less collagen, resulting in common signs of aging such as wrinkles, sagging, and joint discomfort.
Consuming collagen-rich foods and those that supply collagen-boosting nutrients can help your body maintain higher collagen levels, slow visible aging, and support tissue repair.
1. Fish (With the Skin)
Fish, especially when consumed with the skin, is an excellent natural source of Type I collagen, the type most abundant in human skin and critical for keeping it supple and smooth. Salmon, mackerel, and sardines are especially beneficial due to their combination of amino acids and omega-3 fatty acids.
- Key nutrients: Glycine, proline, hydroxyproline, omega-3s
- Best practice: Eat seared or baked salmon with the skin on, or include fish with edible skin in your diet for maximum collagen intake.
2. Red Bell Peppers
Red bell peppers are an outstanding source of vitamin C, a vital nutrient for collagen synthesis. Vitamin C not only supports the binding of amino acids into collagen, but also helps protect existing collagen from free radical-induced damage.
- Key nutrients: Vitamin C, antioxidants
- Tip: The riper the pepper, the higher the vitamin C content. Red peppers offer more vitamin C than green or yellow ones.
3. Tomatoes
Tomatoes, especially sun-dried varieties, are rich in vitamin C as well as lycopene. Lycopene is a powerful antioxidant known for protecting skin from UV-ray damage and preserving collagen integrity. Adding tomatoes to your diet is a delicious way to reinforce the skin’s natural defense system and boost collagen production.
What others are reading
- Sun-dried tomatoes provide a concentrated source of both vitamin C and lycopene.
- Add tomatoes to salads, pastas, and snacks for a collagen friendly boost.
4. Bone Broth
Bone broth is one of the most celebrated sources of collagen. Made by simmering beef, chicken, or fish bones for hours, bone broth extracts collagen, gelatin, and key minerals that help support skin, joints, and immune function. This ancient elixir remains a staple for those seeking natural anti-aging benefits.
- Contains Type I, II, and III collagen.
- Easy to make at home or purchase pre-made options.
- Drink as a warming beverage or use as a base for soups and stews.
5. Berries
All berries—including strawberries, blackberries, raspberries, and blueberries—deliver a punch of vitamin C and ellagic acid, an antioxidant that shields skin from UV-related collagen breakdown. Berries are also low in sugar and provide fiber, making them perfect for healthy snacking and skin maintenance.
- Promotes natural collagen synthesis.
- Protects existing collagen against sun damage.
- Try frozen berries in smoothies for year-round nutrition.
6. Beef
Beef, particularly cuts rich in connective tissue (like brisket, chuck, or shank), is very high in collagen—specifically Type I and III collagen necessary for skin elasticity and firmness. Beef also provides zinc, which is essential for collagen production and healing, as well as the amino acids glycine, proline, and hydroxyproline, key building blocks in collagen synthesis.
- Choose grass-fed or responsibly raised beef whenever possible.
- Add beef stews, slow-cooked roasts, and homemade meat broths to your meals.
7. Citrus Fruits
Citrus fruits such as oranges, lemons, limes, and grapefruits are classic sources of vitamin C. This nutrient is a cofactor in linking the collagen amino acids, supporting new collagen formation and maintaining skin resilience. While other fruits and vegetables may surpass citrus fruits in vitamin C content, a single medium orange still supplies nearly the full daily recommended value.
- Citrus fruits help defend skin against environmental stressors.
- Add fresh lemon juice to water or enjoy citrus segments as a hydrating snack.
8. Eggs
Eggs, including both the yolk and whites, provide a natural source of collagen and the amino acids required to build more. The yolk specifically contains collagen, while the egg whites supply glycine and proline—key for new collagen construction. Eggs also deliver B vitamins for healthy skin and hair.
- Eat eggs in a variety of preparations to maximize benefits: boiled, baked, scrambled, or poached.
- Include the whole egg—yolk and white—for best results.
9. Dark Leafy Greens
Leafy vegetables such as spinach, kale, collard greens, and chard are celebrated for dense nutrition. They offer significant vitamin C, antioxidants, and chlorophyll, the pigment that may support increased procollagen (collagen precursor) production. These greens also protect existing collagen from oxidative stress.
- Work leafy greens into salads, smoothie bowls, sautés, and omelets.
10. Chicken
Chicken is a protein-rich food that supplies every amino acid required for collagen production. Chicken skin and connective tissue provide direct sources of collagen, making slow-cooked chicken soups and stocks especially beneficial.
- Look for bone-in, skin-on chicken when possible.
- Enjoy roasted chicken or include shredded chicken in soups for extra collagen.
11. Legumes
Legumes such as chickpeas, lentils, and beans are potent sources of minerals and protein. Chickpeas, in particular, are loaded with zinc and vitamin C, two nutrients vital for collagen production and tissue repair. Legumes also provide plant-based protein to support structural health.
- Add legumes to salads, soups, or grain bowls.
- Try homemade hummus for a skin-boosting snack.
12. Oysters
Oysters are among the best dietary sources of zinc, a mineral absolutely crucial for collagen synthesis and renewal. Just one or two oysters can provide a day’s worth of zinc, making them an impressive addition to a collagen-supportive diet. They also contain copper, another nutrient essential for the cross-linking of collagen fibers.
- Enjoy oysters raw, steamed, or grilled for a savory collagen-boosting treat.
