Standardized Cistanche, by Life Extension, provides powerful support against immune senescence.

Scientists have discovered that the echinacoside compound found in Cistanche plant extract stimulates the development of naive T cells and leads to a lower amount of memory T cells, thereby creating a more balanced immune response. Cistanche also increases natural killer (NK) cell activity-resulting in a 15% life span increase in animal research.1 A 12-week human study of a dietary supplement containing standardized Cistanche resulted in impressive gains in immune factors after supplementation. Subjects had significant improvements, including an 11.7% increase in natural killer (NK) cell activity and a 20.2% improvement in the ratio of CD4 to CD8 cells. An increased CD4/CD8 ratio is indicative of healthy, youthful immune function.2 *These statements have not been evaluated by the Food and Drug Administration.
