what collagen do
Collagen is made from dietary proteins. As a structural protein, collagen builds connective tissues found throughout your body. While it's essential for tendons and ligaments, collagen does much more than that: It supports soft tissues such as organs, gives resilience to bones and keeps your skin firm. It can fill such diverse jobs thanks to a chain-like structure that can form long filaments and crisscross into sheets of connective tissue.
