The Function of Collagen Protein in the Human Body

Collagen is a protein molecule that provides structural support to connective tissues such as ligaments, tendons, bone, and cartilage. Changes in collagen content can lead to altered tissue function, like reduced elasticity in the skin or pain and reduced function in tendons and ligaments. The most common type of collagen in the human body is type 1. While collagen supplements claim to improve the function of collagen-containing tissues, research shows that collagen protein is not effective for increasing muscle protein synthesis or connective tissue protein synthesis.
