Comprising 25 to 35 percent of our whole-body protein content, it’s the most abundant protein in humans and, in the form of elongated fibrils, is mostly found in fibrous tissues such as tendons, ligaments and skin. The supplementation of collagen peptides provides valuable building blocks for many tissues.
Collagen I is the most abundant collagen of the human body (90 percent); is present in scar tissue; repairs healing tissue; and is found in tendons, myofibrils and the organic part of bone. Collagen II is the basis for articular cartilage and hyaline cartilage, and makes up 50 percent of all protein in cartilage and 85 percent of collagen in articular cartilage. Collagen III is fibrillar collagen, found in extensible connective tissues such as skin, lung and vascular system, and is associated with type I collagen.
