TUDCA (Tauroursodexoycholic acid) is a known ingredient that can rapidly improve your liver function! TUDCA is a component of your bile acid. Your body only produces a small amount, but through oral supplementation you can easily increase the amount of TUDCA in your body. TUDCA helps remove what's jamming your liver bile duct from flowing and to maintain the proper folding process, reduces free radicals, and stops your liver cells from programmed cell death.
