Standardized Cistanche 30 vegetarian capsules Standardized Cistanche 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. 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. For those seeking the effects of Cistanche only, Life Extension has created a standalone Standardized Cistanche that contains the same echinacosides as in the Immune Senescence Protection Formula?.
