What is Collagen?

Collagen is a fibrous, structural protein that can be found throughout the human body (as well as in all mammals) as a connective tissue. Collagen can be found in the skin, bones, muscles, cartilage and even in the teeth. There are more than 20 types of collagens in the body and it makes up about one-quarter of the body’s protein content. The body relies on collagen to literally hold it together. Collagen gives form, firmness and strength to bodily tissues, cartilage, ligaments and internal organs. Collagen production decelerates as we age, causing fine lines and wrinkles in the skin. Collagen is most popular for its role in cosmetic surgery to help firm up the lips and face, giving people a younger appearance, but is also sold as a supplement to help increase and maintain joint mobility and is used in treating burns. Collagen also has many industrial and medical uses.
