Kinoko Gold AHCC for Immune Support - Double
Kinoko Gold AHCC
Significantly Improves Immune Responses
Enhances Function of NK Cells, DC Cells, T Cells, Macrophages and Cytokines
AHCC is backed by over 25 clinical and in vivo studies published in peer-reviewed medical journals and by more than 50 human studies documented in papers and case reports. Research on AHCC has been conducted at highly reputable medical institutions such as the Yale Medical School, Harvard-affiliated Faulkner Hospital and U.T.M.D. Anderson. Several trials - including a 269-subject study published in the Journal of Hepathology, a double-blind, placebo-controlled published trial on healthy adults and a Yale Medical School study on healthy elderly patients - have shown that AHCC can increase the number of activity of:
- Natural killer (NK) cells, the body's first line of defense
- Dendritic cells, which initiate adaptive immune response
- T cells, which provide backup to NK cells
- Macrophages, which clean up cellular debris
- Cytokines, which activate the immune system
