Collagen is the most abundant protein in your body. It is one of the major building blocks of bones, skin, muscles, tendons, and ligaments, and, is also found in many other body parts, including organs, blood vessels, corneas and teeth. You can think of it as the “glue” that holds all these things together. In fact, the word comes from the Greek word “kólla,” which means glue.
Due to a.o. aging and sun exposure, your body produces less and lower quality collagen. One of the visible signs of this is in your skin, which becomes less firm and supple. Cartilage also weakens with age. Having a healthy level of collagen is necessary for maintaining a healthy body and keeping your musculoskeletal system in good condition.
