TUDCA Research Guide

Full name: Tauroursodeoxycholic Acid

A water-soluble bile acid used by biohackers for liver support, cellular stress protection, and gut/bile flow. TUDCA is one of the most searched liver-protective compounds, especially alongside oral compounds or hormone protocols.

How TUDCA Works

Acts as a chemical chaperone that reduces endoplasmic reticulum (ER) stress, inhibits apoptosis, protects mitochondria, improves bile flow and solubility, and provides neuroprotective and cytoprotective effects.

Dosing Protocol

• Typical dose: 250-500 mg per day
• Frequency: 1-2x daily
• Duration: Cycled or ongoing
• Route: Oral capsule

Reported Benefits

• Liver protection and enzyme normalization
• Improved bile flow
• Reduced ER stress
• Mitochondrial protection
• Neuroprotective potential
• Gut barrier support

Potential Side Effects

• Mild GI discomfort
• Diarrhea at high doses
• Rare nausea
