TUDCA is a water soluble bile acid. It shows great potency in treating bile acid backup in the liver as the water soluble bile acids counteract the toxicity of regular bile acids. TUDCA can also protect and help rehabilitate the liver, and in general protects cells from free radical damage. Research has validated TUDCA as a potent and effective treatment for repairing and supporting the liver from alcohol-induced damage, as well as from damage as a result of compounds that must do a double pass through the liver. It also has the ability to promote healthy levels of liver enzymes, which are proteins that accelerate vital chemical reactions in the liver.
