What is Collagen? Collagen is the most abundant structural protein in the body and provides the scaffolding that builds structure and strength in joints. Collagen productions declines with age and athletes are particularly vulnerable to joint-related injuries. Taking collagen peptides kickstarts collagen synthesis and may make tendons, ligaments and joints healthier, stronger, and more resilient.

Gnarly Collagen Pro vs other Gnarly proteins Gnarly Collagen Pro is rich in the amino acids glycine, proline, and hydroxyproline, which are important components of human collagen.
