Collagen-Rich Foods to Add to Your Diet

Collagen is the most abundant protein in the body, giving structure to skin, tendons, cartilage, and bone. Your body makes its own collagen throughout life, but that production naturally slows with age. The good news is that everyday food choices can help: some foods contain collagen or gelatin directly, while others supply the specific nutrients your body needs to build collagen on its own. Here is a practical look at what to put on your plate.

Bone broth

Bone broth is made by simmering animal bones, connective tissue, and skin for many hours, which draws out collagen and converts it into gelatin. The result is a savoury, protein-rich liquid that many people use as a base for soups or drink on its own. While the exact collagen content of homemade broth varies a great deal depending on the bones used and how long it simmers, it remains a traditional and genuinely nutrient-dense way to work more collagen-related protein into your diet.

Fish and shellfish

Fish, particularly the skin, is a good source of collagen, and marine collagen from fish is generally absorbed efficiently by the body. Including fish such as salmon, mackerel, or sardines a few times a week also brings omega-3 fatty acids, which help support the body's inflammation response — a bonus for joint comfort alongside the collagen-building benefit.

Eggs

Eggs, especially the whites, are rich in proline, one of the key amino acids needed to build collagen. Eggs also provide high-quality complete protein, giving the body a full set of amino acid building blocks in one simple, versatile food. They are an easy everyday addition for breakfast, salads, or snacks.

Nutrients that help your body build collagen

Collagen synthesis is not just about eating collagen directly — your body also needs certain cofactors to assemble it properly. Consider including:

• Vitamin C, essential for collagen formation, found in citrus fruits, guava, bell peppers, and leafy greens.
• Zinc, which supports collagen production and tissue repair, found in meat, shellfish, seeds, and legumes.
• Copper, involved in stabilising collagen fibres, found in nuts, whole grains, and organ meats.
• Protein-rich foods generally, such as poultry, dairy, and legumes, which supply the amino acids collagen is built from.

A few practical tips

• Pair a vitamin-C-rich food with your protein at meals — for example, citrus with fish, or peppers with eggs — to support collagen synthesis.
• Use bone broth as a cooking base for soups, stews, or grains rather than relying on it as a stand-alone remedy.
• Limit excess sugar and highly processed foods, which studies suggest can interfere with collagen structure over time.
• Consistency matters more than any single meal — building these foods into your regular routine is what makes a lasting difference.
