Cartilage formation promoter

Safe, by ingesting routinely exhibit chondrogenesis promoting effect, and to provide a chondrogenesis promoter. Further, by ingesting, synthesis promoting effect of the proteoglycan, and to provide a proteoglycan synthesis promoter. Chondrogenesis-promoting agent used as an active ingredient a milk-derived basic protein fraction provides a proteoglycan synthesis promoter. The milk-derived basic protein fraction by ingestion, can promote the synthesis promotion of proteoglycan, and the formation of cartilage. Also, similarly have chondrogenesis promoting effect hydrolyzate was hydrolyzed milk-derived basic protein fraction.
