12 Collagen-Rich Foods for a Healthier Body

Did you know that one-third of your body's total protein is collagen? It also makes up about three-quarters of the dry weight of your skin.

The body's extracellular matrix (ECM)-the network that gives tissues structure and support-is largely made of collagen. This matrix plays a critical role in tissue repair, cellular growth, and maintaining overall strength and flexibility throughout the body.

Benchmark for a Healthier Body

When it comes to health, body composition often matters more than just body weight. Your weight is made up of both body fat and lean (non-fat) mass-such as muscle, bone, organs, and water. Lean tissues are metabolically active and burn energy, whereas body fat primarily serves as a source of stored energy and regulates hormones.

Understanding your body fat percentage gives a clearer picture of wellness than the scale alone. You can estimate your body fat using this calculator, helping you track changes in lean mass and fat over time.

Let's Discuss Collagen

The body produces several types of collagen, each serving a different purpose:

Type I

Accounts for ~90% of the body's collagen, supporting bones, cartilage, skin, tendons, and teeth. Often referred to as the "glue" holding the body together.

Type II

Found in cartilage and supports joint flexibility.

Type III

Provides structural support for muscles, arteries, and organs.

Type IV

Located in the skin's layers, it plays a key role in filtration.

Benefits of a Collagen-Rich Diet

Collagen peptides are small, easily absorbed fragments of collagen proteins typically sourced from bovine or porcine collagen. In addition to whole-food sources, many people choose to supplement to help maintain collagen levels as they age. For example, NuMedica Collagen Connect provides clinically studied FORTIGEL® and VERISOL® peptides to support joints and skin, while Collagen Replete offers a convenient, great-tasting daily collagen boost.*

Whether through food or supplements, increasing collagen intake can support skin elasticity, joint comfort, bone strength, and cardiovascular health. Many people also report improved sleep, hormonal balance, faster recovery, and a more positive mood.

12 Collagen-Rich Foods to Support Your Body

1. Fish with the Skin Left On

Fish skin is rich in Type I collagen. Remove the scales and enjoy the skin for a collagen boost.

2. Tomatoes

Tomatoes, especially sun-dried, are packed with vitamin C, which your body uses to synthesize collagen. Lycopene also helps protect existing collagen from breakdown.

3. Berries

Blueberries, blackberries, raspberries, and strawberries are excellent sources of vitamin C and antioxidants that support collagen formation.

4. Eggs

Egg yolks naturally contain collagen, while the whites provide amino acids essential for collagen production.

5. Greens

Kale, collards, spinach, and chard supply vitamin C and chlorophyll, which may stimulate procollagen production.

6. Red Bell Peppers

These vitamin C powerhouses get sweeter and richer in nutrients as they ripen from green to red.

7. Bone Broth

Simmered animal bones release collagen, making bone broth one of the most traditional collagen sources.

8. Beef

Beef provides zinc and key amino acids-hydroxyproline, glycine, and proline-critical for collagen synthesis.

9. Citrus Fruits

Oranges, grapefruits, lemons, and limes deliver vitamin C, a cornerstone nutrient for collagen formation.

10. Legumes

Chickpeas and lentils provide protein, vitamin C, and zinc, all of which are important for supporting collagen production.

11. Oysters

Rich in copper, which helps form collagen. They're delicious grilled, broiled, or baked.

12. Avocados

Avocados and their oil provide vitamin E and omega-3 fatty acids, both of which support skin health and collagen protection.
