Collagen supplements are everywhere right now. Powders, drinks, capsules—there’s no shortage of products promising smoother skin and healthier joints. But what exactly is collagen, and is supplementation really necessary?

Collagen is a structural protein made up of amino acids such as glycine, proline, hydroxyproline, and arginine. It’s found in skin, muscles, connective tissue, and bones, and it plays a critical role in maintaining strength, elasticity, and hydration in the skin.

Our bodies naturally produce collagen, but production slows with age. Sun exposure, stress, poor diet, and environmental factors can also contribute to collagen breakdown.

The good news? One of the most effective ways to support collagen production naturally is through nutrition.

Eating foods rich in key vitamins, minerals, and antioxidants gives your body the building blocks it needs to produce and protect collagen.

Let’s look at some of the best nutrients and foods that help support healthy skin naturally.
