Collagen is the major structural protein component of the animal extracellular tissue and connective tissues. Collagen is made up of three primary amino acids - glycine, proline, and hydroxyproline. It is found in many different parts of the body, including skin, bones, and muscles, and has got an important supportive, reparative, and protective function.
For animals, especially dogs, collagen is mainly utilized as a functional nutritive supplement. The main purpose of collagen consumption is to maintain joint health. Collagen acts with the help of oral collagen peptides, which can contribute to stimulation of chondrocytes for matrix molecule synthesis of articular cartilage and decreasing the levels of inflammatory factors and enzymes causing degradation of cartilage. Such a way of functioning allows achieving "structural upgrade," and "delay of the disease progress." This contributes positively to the health of animals’ bones, joints, connective tissues, nails, and teeth. Also, this can be used in order to increase immune response of animals. Moreover, it assists in improving the skin condition and the coat of animals.
