Collagen is the substance that literally holds the body together. It is the most abundant protein in the body. Its main role is to provide structural support and strength, however it also protects the vital organs and provides flexibility, support and movement. It is also needed for the replacement and restoration of dead skin cells and to strengthen tendons and ligaments.
