Why Astragaloside IV? * Astragaloside IV is a saponin isolated from various species in the genus Astragalus that is purported to have telomerase activation activity. * The 2009 Nobel Prize in Physiology or Medicine was awarded to three Americans who discovered telomeres, the genetic code that protects the ends of chromosomes, and telomerase, the enzyme that allows for the replacement of short bits of DNA. In the new study the team at UCLA found that the extracts from Astragalus can boost production of telomerase.
