Collagen 101

What is collagen?

Collagen is the most abundant protein in your body, accounting for about one-third of its protein composition.

It’s one of the major building blocks of bones, skin, muscles, tendons, and ligaments. Collagen is also found in many other body parts, including blood vessels, corneas, and teeth.

You can think of it as the “glue” that holds all these things together. In fact, the word comes from the Greek word “kólla,” which means glue.

Are There Benefits to Collagen Supplements?

Some studies show that taking collagen supplements for several months can improve skin elasticity, (i.e., wrinkles and roughness) as well as signs of aging. Others have shown that consuming collagen can increase density in bones weakened with age and can improve joint, back and knee pain.
