AndoSan™ is a potent immune-modulating substance, as demonstrated in pilot trials. There is considerable interest in AndoSan™ from people with various ailments and as a general promoter of immune health.

An independent scientific comparison of mushroom extracts from 2004, based on an animal infection model, identified AndoSan™ as the most promising. Since then, AndoSan has been the subject of more than 20 independent scientific studies in Norwegian institutions and, so far, four completed Ph.D. thesis. As part of long-term medical development, ImmunoPharma has an ongoing project to characterize and identify active substances in AndoSan. So far, this work has resulted in one granted patent

ImmunoPharma has exclusive worldwide rights to the manufacture and marketing of AndoSan. AndoSan™ is produced in ImmunoPharma's production facility located in the mountains near Nagoya in Japan. The precise and time-consuming production process guarantees a formula that is effective, safe, and consistent. The basis for growing the secret strain of the AbM mushroom is securely stored in two geographically separate locations.
