Collagen is the most abundant protein in the human body, providing structural support to skin, bones, tendons, and connective tissues. While there are at least 28 types of collagen identified, five types account for the majority of collagen in the body.
Type I Collagen
Type I is the most prevalent form, comprising approximately 90% of the body's collagen. It provides structure to skin, bones, tendons, fibrous cartilage, connective tissue, and teeth. This type is particularly valued in supplements for supporting skin elasticity and bone density.
Type II Collagen
Found primarily in elastic cartilage, Type II collagen provides cushioning for joints. It's the main component of cartilage and is commonly used to support joint health and mobility.
Type III Collagen
Often found alongside Type I, this collagen supports the structure of muscles, organs, and arteries. It plays a crucial role in cardiovascular health and is important for skin elasticity and firmness.
Type IV Collagen
This type forms the foundation of cell membranes and is found in the layers of skin. It's essential for filtration and provides structural support to blood vessels.
Type V Collagen
Type V is necessary for the formation of cell surfaces, hair, and the placenta during pregnancy. It works in conjunction with Type I collagen in many tissues.
Choosing the Right Collagen
Understanding these different types helps in selecting the appropriate collagen supplement for specific health goals, whether for skin health, joint support, or overall structural integrity.
