Deep dives
Overview of Collagen
Collagen, a popular supplement, is a protein sourced from animal connective tissues like bones, ligaments, and tendons. Unlike complete proteins, collagen lacks the amino acid tryptophan out of the 20 essential amino acids that make up proteins. This impacts its classification as a complete protein. Despite this, collagen is rich in glycine, proline, and hydroxyproline, which are crucial for skin, connective tissue, and bone health.
