Collagen is an essential component for skin, bones, muscles and tendons. It’s also involved in helping your blood clot. It’s found in foods of animal origin, and is concentrated in the skin and joints. This means it’s present in recipes that use the bones and skin of fish, shellfish, poultry, beef, lamb and other proteins.
Foods that contain gelatine, like bone broth, are also a good source of collagen. But, studies suggest it may not result in increased collagen levels as much as taking a supplement.
