TUDCA (Tauroursodeoxycholic Acid) is a water-soluble bile acid naturally synthesized in small quantities by the body and has a long history of use in traditional Chinese medicine. As a dietary supplement, TUDCA is highly regarded for its role in supporting liver health by improving bile flow from the liver to the intestines, which helps facilitate proper digestion and detoxification. In addition to its liver-supportive properties, TUDCA provides powerful neuroprotective effects. It helps shield brain cells from oxidative damage and supports healthy neural function, which may contribute to improved cognitive resilience. Furthermore, TUDCA plays a role in maintaining retinal health, offering protective benefits to the eyes.
