What is Collagen?

Collagen is a protein. It is the main structural protein that is contained in the extracellular space in the body’s connective tissues. Although different than the characteristics of commonly known proteins, collagen has a unique amino acid composition which provides the human body with benefits that you can see and feel. Amino acids are essentially the building blocks of proteins in the human body. Collagen’s amino acid profile is unique in the fact that it contains higher amounts of Glycine and Proline. The human body produces collagen naturally, but only under optimal conditions, and in diminishing amounts as we age. This is why supplementing ones diet with collagen powder or bone broth can be optimal for individuals looking to boost their natural levels.

Derived from the Greek word “kólla“, meaning “glue” and the French “-gène”, meaning “something that produces”. Collagen can be thought of as the glue that supports connective tissues within the body, building strength and integrity. Specifically, collagen is shown to support tendons, cartilage, bones, skin, muscle mass and even the sclera of the eye.

But What Are The Different Types Of Collagen?

There are at least 28 types of collagen that have been identified, with most of the ones found in the body being type I, II, and III.

Type I - Type one is the most prevalent in the human body. Most recommended for individuals looking to support hair, skin, and nail health. Generally speaking, it is the most well-rounded protein for human health.
Type II - Type two is a bit more specialized. It is the main collagenous ingredient found in cartilage. Beneficial for those looking to focus on joint health.
Type III - Usually found alongside type one, type three can be found in the body's reticular tissues (bone marrow, liver, adipose tissue, and more).
Type IV - Type IV collagen is the main collagen component of the basement membrane. It is a network-forming collagen that underlies epithelial and endothelial cells and functions as a barrier between tissue compartments.
Type V - Collagen V can be found in the bone matrix, cornea, and in the connective tissue that exists between the cells of the muscles, liver, lungs, and placenta.
Type X — Type X helps with new bone and articular cartilage formation. Its a network-forming collagen helping in the creation of bone tissue in the body.
