Collagen

Synonym(s): Collagen, Native Collagen
Nutrient group: Active agents for joints & tissues

Sources and physiological effects

Dietary sources
Collagen is an animal protein contained in the cartilage, bones, skin and rind of domesticated and wild animals. Cooking these animal components dissolves collagen in water purified and dried collagen is known as “gelatine“. This is used to bind various creams and mousses or for jelly and aspic. 
Physiological effects
Connective tissue
  • Important structural protein in connective tissue (bones, teeth, cartilage, tendons, ligaments) Most abundant protein in the human body

Detailed information

Native Collagen (Type II) in degenerative joint diseases
Combination preparations are gaining ground in the nutritional therapy of degenerative joint diseases. Besides glucosamine, chondroitin and hyaluronic acid, native collagen has moved into the focus of the scientific community.1 Native collagen (type II) is an essential component of cartilage tissue. Only native type II collagen has the special triple helix required for tear-resistant collagen fibers. As a catalyst, native collagen (type II) also stabilizes tendons and connective tissue. In contrast to chondroitin and glucosamine, which act slowly, native collagen (type II) exhibits a clear improvement of all parameters after only 90 days of use. Among other effects, oral administration led to a 33 % reduction on the WOMAC scale.2 In a study of 40 knee osteoarthritis patients, the combination of native collagen (type II) and Boswellia serrata resulted in a significant reduction in pain, stiffness and improvement in physical function.3 
 
Collagen type I for degenerative tendon diseases 
Type I collagen is mainly responsible for the structure and loading capacity of the tendon. Over 95% of the collagen of the tendons is collagen type I.3 The intake of collagen type I induces a significant increase in collagen fibril diameter and also alters the mucopolysaccharide composition in the extracellular region of the tenocytes, resulting in improved tendon function.4 
 
Copper - Cofactor of connective tissue synthesis
Copper status probably also plays a role in joint inflammation. Lower copper values are associated with an increased incidence of inflammation. In addition, copper deficiency impairs collagen and elastin metabolism.5 The copper-containing enzyme lysyl oxidase is essential for the formation and cross-linking of collagen and elastin, which is why a copper deficit can lead to connective tissue disorders. For the optimal effect of collagen, sufficient copper levels should therefore be ensured.
