AHCC (active hexose correlated compound) is a natural substance extracted from certain species of basidiomycetes (a class of mushrooms that includes [[shiitake]]). Available in supplement form, AHCC is known to act as an antioxidant. While research on AHCC's heath effects is fairly limited, proponents claim that taking AHCC can produce a variety of health benefits.
==Special Precautions of AHCC==
Little is known about the safety of long-term use of AHCC. However, there's some concern that AHCC may trigger mild side effects, including diarrhea and itching.
