Chondroitin sulfate is a glycosaminoglycan extracted from porcineíóbovineíóchickeníóand shark cartilage. It is used for the auxiliary treatment of neural-headache, neuralgia, arthritis, hemicrania and be effective in reducing the blood lipid. The chondroitin sulfate can also be used as additive in the foodstuff and the healthy products. We are the first group of people in china who developes in the field of chondroitin sulfate manufacturing.
