Qingdao Kehaijiantang Biochemistry Co., Ltd.

Qingdao Kehaijiantang Biochemistry makes marine biological raw materials, principally collagen peptide and marine fish oligopeptide. Both are enzyme hydrolysates of fish skin and fish protein cut to low molecular weight, which is what makes them dissolve cleanly and absorb quickly; supplement, drinks and cosmetic formulators buy them on that basis. The company manufactures in Qingdao, Shandong, next to the fish processing that yields the raw material.
