Is Collagen a Protein?

Published in Protein Type 2 mins read

Yes, collagen is a protein. In fact, it's the most abundant protein in your body, making up about 30% of your total body protein.

What is Collagen?

Collagen is a crucial structural protein found in your body's connective tissues. It provides strength and support to:

  • Skin
  • Muscles
  • Bones
  • Tendons
  • Ligaments
  • Organs
  • Blood vessels
  • Intestinal lining

As noted by Cleveland Clinic (https://my.clevelandclinic.org/health/articles/23089-collagen), collagen provides structure, support, or strength to various tissues. Healthline (https://www.healthline.com/nutrition/collagen) confirms that collagen is a protein found in connective tissue, skin, tendons, bones, and cartilage, providing structural support. Wikipedia (https://en.wikipedia.org/wiki/Collagen) further emphasizes that it's the main structural protein in the extracellular matrix of connective tissues. WebMD (https://www.webmd.com/diet/collagen-health-benefits) highlights its role in healthy joints and skin elasticity. Furthermore, sources like News-Medical (https://www.news-medical.net/health/What-is-Collagen.aspx) explain that collagen is composed of amino acids, the building blocks of proteins.

Collagen's Importance

Collagen's role extends beyond structural support. It plays a vital role in maintaining healthy skin, joints, and overall bodily function. Many supplements utilize collagen peptides, as evidenced by Vital Proteins' product description (https://www.vitalproteins.com/products/collagen-peptides), which highlights collagen's support for hair, nails, skin, bones, and joints.
