Collagen plays a vital role in the human body as a major component of connective tissue. It provides structural support and strength to various tissues, including skin, bones, tendons, and ligaments. Collagen fibers help maintain the flexibility and resilience of these tissues, allowing them to withstand stretching and pressure. Additionally, collagen contributes to the healing process and promotes the overall health and integrity of the body’s structures, making it crucial for wound healing and joint health.
