What is it?

  • Collagen is the most abundant protein within the body, residing in the extracellular matrix (ECM) of several tissues including skin, bone, ligaments and tendons.1 It is unique in that it forms as a triple helical structure, resulting in a rigid and durable tissue, which provides structure and support to the body, as well as playing a role in locomotion.2 To date, there are 28 different types of collagen known which are composed of polypeptide chains.3
  • Within bone, muscle and connective tissue, Type 1 collagen predominates, consisting of non-essential amino acids (NEAAs) including glycine, proline, hydroxyproline and hydroxylysine.4 The specific role of each of these AAs and/or peptides after the consumption of collagen is still being explored.
