Life Extension Immune Senescence Protection Formula, 60 vegetarian tablets

This formula focuses on supporting three types of immune cells: naïve T cells, memory T cells and natural killer (NK) cells. Naïve T cells attack new invaders.1 Memory T cells attack previously-known invaders.2 And NK cells function as your body’s first responders.3 When a naïve T cell encounters a new threat, it remembers it, becoming a memory T cell. This means we naturally develop a surplus of memory T cells over time.4 So to maintain a healthy immune system, we need to support a youthful ratio of naïve to memory T cells, promote healthy naïve T cell production and encourage NK cell activity. Cistanche rejuvenates the immune system The cistanche plant contains a compound called echinacoside. It stimulates naïve T cell development, which in turn supports a healthy ratio of naïve-to-memory T cells.5,6 Cistanche also increases NK cell activity. In pre-clinical research, cistanche supported a 15% life span increase for NK cells.5 In a 12-week clinical study, standardized cistanche produced an 11.7% increase in NK cell activity and a 20.2% improvement in the ratio of CD4 to CD8 cells, an indicator of youthful, healthy immune response. 7 Reishi mushroom inhibits immune senescence Pre-clinical research indicates that reishi mushrooms may help inhibit the factors of immune senescence and promote longevity.8,9 This species is packed with polysaccharides, triterpenes and other compounds that boost the function of hematopoietic stem cells, T cells and immune factors that serve as your body’s defense, thus inhibiting immune senescence. 8,10 Pu-erh tea extract supports immune balance Pu-erh tea is made from the same plant as black and green tea. But this kind of tea is a little different: it’s rich in polyphenols and other bioactive molecules that support immune health. In a pre-clinical study, pu-erh extract produced a 7% increase in NK cells and a 10% increase in naïve T cells. In the same study, pu-erh tea extract promoted healthy bone marrow function, which helps rebuild peripheral immune cell components.11
