What is collagen?
Collagen is like the scaffolding of our body. It’s a type of protein that holds everything together, kind of like glue. You can find it in your skin, bones, muscles, tendons, and ligaments. It’s what gives your skin its strength and elasticity, keeping it smooth and firm. Collagen also plays a role in the health of your hair and nails. Plus, it helps your joints move smoothly by cushioning them.
As we age, our bodies produce less collagen, which can lead to wrinkles, joint pain, and weaker bones. That’s why some people take collagen supplements or use collagen-rich skincare products to try to boost their levels. Eating foods like bone broth, fish, and chicken skin can also help your body make more collagen naturally.
