Collagen is the most abundant protein in the human body and is the substance that holds the whole body together. It is found in the bones, muscles, skin and tendons, where it forms a scaffold to provide strength and structure.1,2
Endogenously produced collagen (i.e. collagen synthesised by the body) plays numerous important roles in health, with the breakdown and depletion of the body's natural collagen associated with a number of health problems. As such, exogenous (supplemental) collagen is increasingly used for medical and cosmetic purposes, including to help with healing and repair of the body's tissues.
