Collagen is the body’s most important building block and it makes up approximately 30% of the proteins in our bodies. Collagen is the key structural protein that ensures the cohesion, elasticity and regeneration of all our connective tissues, including skin, tendons, ligaments, cartilage and bones. In essence, collagen is strong and flexible and is the ‘glue’ that holds everything together. It strengthens various body structures as well the integrity of our skin. There are many different types of collagen in our body, but 80 to 90 percent of them belong to Type I, II or III, with the majority being Type I collagen. Type I collagen fibrils have enormous tensile strength. This means they can be stretched without being broken.
Different cells in our body tissues are responsible for the production of collagen. The cells use specific amino acids and peptides as building blocks for the production of the large collagen helix structure. This is then organized into the strong fibers that provide structural tissue support, flexibility and the ability to withstand forces.
