Collagen (Infographic)

Here are some key points about collagen.
  • Protein makes up around 20% of the body's mass, and collagen makes up around 30% of the protein in the human body.

  • There are at least 16 types of collagen, but 80-90% of the collagen in the body consists of types I, II, and III.

  • Type I collagen fibrils are stronger than steel (gram for gram).

  • Collagen is most commonly found within the body in the skin, bones and connective tissues.

  • The word "collagen" is derived from the Greek "kolla," meaning glue.

  • Collagen gives the skin its strength and structure, and also plays a role in the replacement of dead skin cells.

  • Collagen production declines with age (as part of intrinsic aging), and is reduced by exposure to ultraviolet light and other environmental factors (extrinsic aging).

  • Collagen in medical products can be derived from human, bovine, porcine and ovine sources.

  • Collagen dressings attract new skin cells to wound sites.

  • Controllable factors that damage the production of collagen include sunlight, smoking and high sugar consumption
