LONZA: Non denaturing type II collagen is produced by low-temperature extraction of chicken breast cartilage as raw material. This product is a high molecular weight collagen that retains the triple helix structure of collagen and is insoluble in water and ethanol. This type of collagen is extracted using low-temperature professional technology, preserving the original triple helix structure of collagen and therefore possessing biological activity. After oral administration, it induces immune tolerance in intestinal lymph nodes, promotes the secretion of anti-inflammatory factors by immune cells, blocks joint inflammation, and prevents cartilage degradation. At the same time, it also promotes the secretion of cell growth factors by immune cells, stimulating the synthesis and repair of articular cartilage. Application scope of non denaturing type II collagen UC-II: food, medicine.
