Collagen is a key component in bones, skin, muscles, and other body parts. It may help improve skin health, relieve joint pain, and prevent bone loss, among other things.
 
Collagen is a protein. Your body makes it, and it’s important for healthy joints, skin, bones, muscles, and more. But as you age — just when it’s harder for your body to make collagen — the collagen you have begins to break down. So, you may be considering collagen supplements and wondering how much they really help.
 
Collagen is the most abundant protein in your body. You can increase your intake of collagen by taking supplements or eating animal foods and bone broth. However, absorption from food may not be as efficient as from supplements.
