AHCC® is a patented, low-molecular weight medicinal mushroom extract developed from the mycelia (or underground portion) of a particular subspecies of Lentinula edodes. Supported by more than 30 human clinical studies, AHCC prompts an early activation of the immune system.* It works by enhancing the production of cytokines (immune-signaling molecules) and increasing the activity of certain white blood cells, including NK cells, DC cells, T-cells, and macrophages.* AHCC® cultured extract of hybridized medicinal mushroom mycelia (roots) is one of the world’s most researched specialty immune supplements. Over 30 human clinical studies support AHCC. Studies on AHCC have been conducted at some of the finest institutions worldwide. These include Ivy League universities and major health centers.
