Tauroursodeoxycholic acid (TUDCA) is a hydrophilic bile acid gaining popularity for its potential to support liver health and protect cells from stress. Here is what the science says about this increasingly popular ingredient.
What is TUDCA?
- A bile acid formed when the amino acid taurine binds to UDCA
- Found naturally in the bile of bears (historically) and humans
- More water-soluble than many other bile acids

Key potential benefits
1. Liver support
- Promotes healthy bile acid flow
- Supports liver cell health and function
2. Cellular protection
- Helps reduce endoplasmic reticulum (ER) stress
- Acts as a cytoprotective agent
3. Metabolic support
- Studied for effects on metabolic health
Supplement use
TUDCA is widely used in supplement form for liver and metabolic support. High-purity TUDCA ensures reliable quality for those seeking these benefits.
Always consult a healthcare professional before using bile acid supplements, especially with existing conditions.
