Collagen is the main component in connective tissue which forms the biological glue, connecting cells together and creating a communication network between cells. Collagen builds our skin, blood vessels, cartilage, ligaments, tendons, bones, teeth, and other structures and organs in the body.With age, collagen begins to weaken and becomes less pliant. And the visible result is dry, wrinkled skin. Adequate collagen production is critical for general health, for supporting strong coronary arteries, maintaining healthy cartilage and bones, and improved function of many internal organs.
