What is TUDCA?
TUDCA (tauroursodeoxycholic acid) is the taurine conjugate of UDCA (ursodeoxycholic acid), a naturally occurring bile acid. It has been used clinically in Asia for decades for liver conditions and has an extensive Western research base accumulated over the past 30 years. It is approved as a drug in some jurisdictions for specific liver conditions.
⚠ Research Context: While TUDCA has clinical applications in some countries, the research-grade TUDCA sold by vendors on this site is sold for research purposes only and not for self-medication.
TUDCA Liver Protection Research
TUDCA's most established research application is hepatoprotection. Published research demonstrates several mechanisms:
- Reduces endoplasmic reticulum (ER) stress in hepatocytes
- Inhibits apoptosis pathways in liver cells (reduced caspase-3 activation)
- Improves bile flow and reduces cholestasis
- Antioxidant activity in hepatic tissue
| Research Area | Finding | Evidence Level |
|---|---|---|
| Liver protection (general) | Significant hepatoprotective effects | Multiple human trials |
| Cholestasis | Approved treatment in some countries | Clinical use |
| ER Stress Reduction | Potent inhibitor across multiple models | Preclinical + human data |
| Neuroprotection | Promising preclinical data (ALS, PD models) | Preclinical |
| Insulin Sensitivity | Improved insulin signalling in obese models | Preclinical + pilot human data |
TUDCA in SARM Research Protocols
TUDCA is commonly studied alongside oral research compounds that undergo hepatic processing. Its well-documented hepatoprotective mechanisms make it a logical co-administration compound in research protocols involving liver-processed substances. Research into LGD-4033, RAD-140 and other SARMs often includes liver biomarker monitoring, and TUDCA research is frequently conducted alongside these protocols.
TUDCA Research Dosing Data
| Research Context | Dose Range Studied | Duration |
|---|---|---|
| Liver protection (general) | 500–1000 mg/day | 8–24 weeks |
| Cholestatic conditions | 10–15 mg/kg/day | Variable |
| Insulin sensitivity | 1750 mg/day | 4 weeks (Kars et al., 2010) |

Frequently Asked Questions
TUDCA is researched primarily for hepatoprotection (liver protection), endoplasmic reticulum stress reduction and bile acid modulation. It has clinical applications in some countries for specific liver conditions. Sold for research purposes only on this site.
TUDCA's hepatoprotective research profile makes it a common co-administration compound in research protocols involving liver-processed substances. Published research supports its ability to reduce hepatocyte stress and apoptosis.
TUDCA is the taurine conjugate of UDCA. Research suggests TUDCA has superior bioavailability and may have stronger cytoprotective effects than unconjugated UDCA.
