Collagen is becoming more sacred in the name of beauty; some doctors and consumers consider it the 'elixir' to restore youthful and radiant skin. In the realm of medicine, collagen is scientifically known for its re-constructive capabilities, that's why it has really something enticing to offer medically and aesthetically.
But really, aside from its beautifying benefits, do we really know enough about collagen? Perhaps an 'encyclopedia' definition would make us understand more about collagen - how it works, its composition, and its other benefits to the human body.

There are over 28 different types of collagen that gives strength and structure to many parts of the body. About 30% of the total protein content of the human body is collagen, making it the most abundant protein found in mammal species. Collagen is abundant in fibrous tissues such as skin, ligaments and tendons, as well as in the bones, blood vessels, the cornea of the eye, and in the gut that's why it is more often described as the "glue that holds the body together".
