Collagen is a protein that acts as the "glue" that holds our tissues together. Although there are at least 28 different types, the best known and most studied are type 1 collagen, type 2 collagen, and type 3 collagen. These are the ones that play the most relevant role in the health of the skin, bones, joints, and muscles.

It is the most abundant in the body, representing about 90% of total collagen. It is found mainly in the skin, tendons, bones, and ligaments. It is responsible for providing firmness and strength to these tissues. That is why, when talking about collagen for the skin or to help with wrinkles, it almost always refers to type 1.

This type is found mainly in cartilage and is essential for joint health. If you have issues with your knees, hips, or any other joint, type 2 collagen is the one that helps keep that cartilage strong and healthy, acting as a kind of natural shock absorber.

It is found in the walls of blood vessels, in muscles, and in some internal organs. It usually works in combination with type 1 collagen to support soft tissues. In addition, it is key in wound-healing and muscle tissue repair processes.
