Cycloastragenol is a tetracyclic triterpenoid sapogenin derived from the root of the leguminous plant Astragalus membranaceus. It is also an active metabolite of Astragaloside IV. Due to its potential to activate telomerase and support telomere length, it is often referred to as a “telomere guardian.” It has attracted significant attention in the fields of anti-aging, neuroprotection, immune regulation, and skin health. It is widely used in dietary supplements and nutritional health product formulations.
