The product components affect collagen production, which is the main tendon component responsible for elasticity and stretchability of the tendons. They also stimulate the reconstruction of articular cartilage. Collagen is the main connective tissue protein. Collagen fibers located in the intercellular substance of connective tissue constitute an important building element with exceptional mechanical properties. They are flexible, resilient and stretchy. Vitamin C contributes to normal collagen formation for the normal function of blood vessels, bones, cartilage, gums, skin, and teeth. Vitamin C also helps protect cells against oxidative stress. Hyaluronic acid is one of the important components of connective tissue and joint fluid. It is responsible for cartilage elasticity, regulates cartilage repair processes and ensures adequate viscosity of the synovial fluid.
