How to Choose
Why TUDCA Quality Matters More Than Most Supplements
TUDCA is synthesized by conjugating taurine with ursodeoxycholic acid (UDCA) — a process that requires careful chemistry. Low-quality manufacturing can result in products containing mostly UDCA (which is cheaper) rather than true TUDCA. Always choose products with third-party testing that specifically verifies TUDCA content.
TUDCA Dose Guidelines
General liver maintenance: 250mg daily. Targeted liver and bile flow support: 500mg daily. Higher doses (1000-1500mg) are used in clinical research settings and should be supervised by a healthcare provider. Start with 250mg and increase if needed. Take with meals for best tolerance.
How We Evaluate
Every product is scored against these weighted criteria. Our ratings reflect clinical evidence and product quality, not commission rates.
Purity & Manufacturing
30%TUDCA is synthesized through a complex process conjugating taurine with ursodeoxycholic acid. Manufacturing quality directly impacts purity. Third-party testing is essential to verify actual TUDCA content.

Third-Party Testing
25%Independent verification of TUDCA identity, potency, and purity. Critical for this category due to the complexity and cost of TUDCA synthesis — adulteration risk is higher than most supplements.
Brand Transparency
10%Clear sourcing information, manufacturing standards, and Certificate of Analysis availability.
Value
10%Cost per serving relative to TUDCA dose and verified purity. TUDCA is inherently expensive; very cheap products may indicate quality concerns.
