It’s tempting to dismiss how potent TUDCA can be for your health if you think of it only in terms of digestion. Stimulating bile flow impacts your health in every area. This is why health practitioners are increasing their focus on getting your liver bile duct to flow well. It improves your: Liver Mitochondria, Intestines, Microbiome, Thyroid, Heart & Brain.


TUDCA is one of my personal favourites. I use TUDCA if I have digestive issues or want a boost in metabolism (TUDCA increases thyroid output). TUDCA is also excellent for improving fat digestion.
