Background
- Active hexose correlated compound (AHCC) is an alpha-glucan-rich dietary supplement extracted from the vegetative part of Basidiomycota mushrooms, such as shiitake (Lentinula edodes).
- AHCC is thought to stimulate the immune system and to reduce the adverse effects of chemotherapy. AHCC was developed in Japan in 1992 and may also have antioxidant and anticancer activity,prevent the onset of diabetes, and prevent liver injury.

AHCC has been shown to reduce chemotherapy-related side effects and enhance antitumor effects. Early evidence suggests that AHCC supplementation may improve the prognosis of cancer patients. However, there are not enough data to make a conclusion. Further research is needed.
Early evidence suggests that AHCC intake may improve glycemic control in patients with diabetes. However, data remain insufficient upon which to base a conclusion. Further research is required.
