There are several different types of collagen, each with a unique structure and function in the body. Here are the five most common types of collagen:

  1. Type I Collagen: Type I collagen is the most abundant form of collagen in the body, and is found in skin, bone, tendons, and other connective tissues. It provides structure and support to these tissues, and is essential for maintaining their strength and integrity.

  2. Type II Collagen: Type II collagen is found primarily in cartilage, and is important for maintaining the flexibility and shock-absorbing properties of this tissue. It is also found in the vitreous humor of the eye, where it helps to maintain its shape.

  3. Type III Collagen: Type III collagen is found in skin, blood vessels, and other organs, and plays a key role in supporting their structure and function. It is often found in conjunction with Type I collagen.

  4. Type IV Collagen: Type IV collagen is unique in that it forms a two-dimensional network, rather than a three-dimensional fibril structure. It is found in basement membranes, which provide a barrier between different types of tissue in the body.

  5. Type V Collagen: Type V collagen is found in smaller quantities than the other types of collagen, but is still important for maintaining the structure and function of tissues such as bone, skin, and tendons.


Each type of collagen has its own unique properties and functions in the body, and can be targeted with specific supplements or treatments depending on the individual’s needs. Understanding the different types of collagen can help individuals make informed decisions about which supplements or treatments are best for their specific health goals.
