Life Extension Standardized Cistanche, 30 vegetarian capsules

Standardized Cistanche provides powerful support against immune senescence. Researchers have found evidence that Cistanche extracts help support healthy glucose metabolism, promote a healthy inflammatory response and maintain already-healthy blood pressure and lipid levels.1 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 supporting a healthy immune response. Cistanche polysaccharides have also demonstrated positive modulatory effects on T cells and may support vaccine responsiveness.2 Cistanche also increased natural killer (NK) cell activity, resulting in a 15% life span increase in animal research.3 In addition, Cistanche and echinacoside have been found to scavenge free radicals, maintain healthy nervous system function and promote longevity.4-8 A 12-week human study of a dietary supplement containing standardized Cistanche showed that it encouraged impressive immune factor support after supplementation. Subjects had a 11.7% increase in natural killer (NK) cell activity and a 20.2% increase in the ratio of CD4 to CD8 cells.9 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.
