The maitake mushroom (Grifola frondosa) is the source of immune enhancing compounds that are being shown to offer significant health benefits, including potential to prevent and assist in the treatment of cancer.

The binding of the beta-glucan triggers a chain reaction leading to increased immune activity.

Reduced bone marrow production increases risk of infection and cancer. This benefits cancer patients undergoing radiation or chemotherapy.
