Genistein Combined Polysaccharide (GCP�) has gained the attention of researchers worldwide through the International AHCC Research Association, founded in 1986 to promote the further study of AHCC. Each year since 1994, over 350 medical doctors and researchers have gathered in Sapporo, Japan for the AHCC Research Association symposiums, where GCP was originally introduced.

Various clinical trials have demonstrated GCP mechanism as anti-angiogenesis, apoptosis and immune system support.* GCP has been the subject of numerous clinical studies conducted at prestigious institutions such as Kansai University, Osaka University, Kitasato University and the Tajima Clinic in Japan and in the United States at Columbia University and the University of California at UC Davis.
