Based on 9 publication(s) in Google Scholar
Cycloastragenol (Astramembrangenin), the active form of astragaloside IV, has anti-oxidant, anti-inflammatory, anti-aging, anti-apoptotic, and cardiovascular protective effects. Cycloastragenol is a potent telomerase activator and can lengthen telomeres. Cycloastragenol alleviates age-related bone loss and improves bone microstructure and biomechanical properties.
