1 Collagen is most commonly found within the body in the skin, bones and connective tissues. 2  The word collagen is derived from the Greek kolla, meaning glue. 3  Collagen gives the skin its strength and structure, and also plays a role in the replacement of dead skin cells. Protein makes up around 20% of the body's mass, and collagen makes up around 30% of the protein in the human body. 2  There are at least 16 types of collagen, but 80-90% of the collagen in the body consists of types I, II, and III. 3  Type I collagen fibrils are stronger than steel (gram for gram).
