AHCC (Active Hexose Correlated Compound) is an extract obtained from a hybridization of several species of mushroom mycelia. AHCC supports normal immune function and may improve the number and functions of immune system cells. Benefits of AHCC: In numerous human clinical trials AHCC has been shown to modify both the innate and adaptive immune response, by potentially increasing the production of cytokines, increasing the activity of Natural Killer (NK) Cells and possibly increasing populations of Macrophages. Dendritic and T cell numbers also could increasethus enhancing normal immune function against viruses and other intruders. NK Cells, Dendritic Cells, T Cells and Marcophages are Immune System Cells.
