AHCC® Plus combines AHCC®, a proprietary compound researched extensively for its immune enhancement properties, with three powerful immune and cellular defense nutrients - selenium, tocotrienols, and gammavitamin E. According to human and animal research, AHCC may significantly increase Natural Killer (NK) Cell activity, increase macrophage activity, enhance cytokine production, support healthy liver function, as well as act as an antioxidant. Some scientific evidence suggests that consumption of selenium and antioxidant vitamins may reduce the risk of certain forms of cancer. However, the FDA has determined that this evidence is limited and not conclusive. *
