1. Bone Broth: Made by simmering animal bones (beef, pork, or chicken) for a long time, bone broth is rich in type 1 collagen, which leaches from the bones into the liquid.
2. Gelatin: Gelatin, a processed form of collagen, dissolves in hot water and is used in jello and gummy candies. It contains amino acids needed for collagen but often has added sugars.
3. Leafy Greens: Leafy greens such as spinach and kale are good sources of vitamin C and chlorophyll, which may help with collagen synthesis.
4. Sardines: Eating sardines whole, including their skin, provides collagen from their skin, tissues, and bones, which can benefit skin texture and hydration.
5. Beans: Beans provide plant-based protein and amino acids needed for collagen synthesis, with one cup offering 15–16 grams of protein.
6. Chicken with Bones and Skin: Chicken cuts with bones and skin, especially feet, are high in collagen. Opt for these parts instead of boneless, skinless chicken.
7. Bell Peppers: High in vitamin C, bell peppers support collagen production. A half-cup of bell peppers exceeds the daily vitamin C requirement.
8. Berries: Berries, including strawberries and blueberries, are packed with vitamin C, which supports collagen production.
9. Organ Meats: Organ meats like liver, heart, and kidneys are rich in collagen protein, providing a substantial collagen boost.
10. Eggs: Egg whites contain amino acids like proline and glycine, essential for collagen production.
