It is the major component of connective tissues which provides structure to much of the body, including our skin, bones, tendons, ligaments and muscles. As well, collagen provides structure to our arteries, which are the blood vessels that carry blood from our heart to the rest of our body. Without enough collagen, arteries may become weak and fragile. Studies have shown that, supplemental collagen, may help improve skin texture and muscle mass, as well as reduce osteoarthritis pain.
