MaitakeGold 404® extract, patented in 1998, is derived from a proprietary strain of Maitake mushroom. This concentrated extract has been found to contain a uniquely bioactive protein-glucan complex showing significant immune stimulatory activity to the body’s complement of immune cells.
Recent in vivo bioactivity testing conducted by renowned U.S. researcher and immunology specialist Vaclav Vetvicka, PhD has confirmed that, even in low doses, MaitakeGold 404® is a highly active immunomodulator. The most recent research report noted that its immunostimulatory activity focused mainly on cellular immunity, showing high activity both in phagocytosis and in stimulation of cytokine release, specifically Interleukin 1, Interleukin 2 and TNF alpha, as well as in natural killer cell (NK cell) stimulation. Since phagocytosis is a critical component of the body’s first line of defense in immunity, this data further validates MaitakeGold 404® as a superior choice for daily immune defense.
