Collagen is the fibrous structural protein that makes up the white fibres (collagen fibres) of skin, tendons, bones, cartilage, and all other connective tissues. Collagen is the natural protein that constitutes most of the body's structural support. It is this fibrous connective tissue that holds our body together.
Collagen gives strength and elastic properties to different organs and tissues. Twenty-five percent of the human body's proteins are made up of collagen and seventy-five percent of our skin is made of collagen. When there is a lack of collagen in the body, everything is affected.
