Collagen peptide is the hydrolyzed form of collagen derived from marine (Fish skin &scale).It is a fibrous protein present in the extralar . After hydrolysis the product loses its gelling ability and makes it soluble in cold water. Collagen Peptide is also known as "Collagen Hydrolysate", "Gelatin Hydrolysate", "Hydrolysed Collagen". Fish/ marine collagen peptides have very specific amino acid compositions with a high concentration of glycine, hydroxypropron>. When fish collagen is ingested, hydroxyproides are not completely digested to free amino acids and can be detected in the blood. These hydroxyproides stimulate in the skin, joints and bones, and lead to collagen synthesis through activation and growth.
