TUDCA (Tauroursodeoxycholic Acid)

Category: Detox & Antioxidant. Status: OTC supplement / Investigational.

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 it 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.

Key facts

  • Molecular weight: 571.81 Da
  • Half-life: Variable (enterohepatic recirculation)
  • Bioavailability: Moderate oral
  • Storage: Room temperature, keep dry.

Dosing overview

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

Protocol notes

  • Liver support: 250-500 mg/day, often on an empty stomach.
  • During oral compound cycles (e.g. orals that stress the liver), 500 mg/day is common.
  • Split dosing (250 mg twice daily) can improve tolerance.

Reported benefits

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

Possible side effects

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

Research

  • TUDCA and hepatic ER stress (2021): Reduced markers of ER stress and improved insulin sensitivity in metabolic-syndrome models.
  • TUDCA neuroprotection (2020): Demonstrated anti-apoptotic and neuroprotective effects in models of neurodegeneration.

Community reviews of TUDCA

Rated 4.3 out of 5 from 3 community reviews by ResearchSafe members.

  • baseline_ben rated it 5/5 - Noticed clear benefits within weeks: Added TUDCA to my protocol about 6 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • vial_vault_vicky rated it 4/5 - Genuinely effective after 3 months: Been using TUDCA for about 3 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • lab_notes_tom rated it 4/5 - Worth adding to the protocol: TUDCA has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
