TUDCA tauroursodeoxycholic acid
A bile acid — the taurine-conjugated form of UDCA, which is itself a licensed medicine for bile duct disease and gallstones. TUDCA is sold as a supplement.
Cholestatic liver disease. The strong evidence belongs to UDCA, the licensed drug — not to TUDCA the supplement, whose own human trials remain small.
No effect on sex hormones.
Does not reduce weight or fat. In 20 obese people (Kars 2010, 1,750 mg/day for four weeks) liver and muscle insulin sensitivity improved, but body weight did not change and adipose tissue did not improve.
Nothing to do with sleep.
Liver and bile flow. It was trialled for ALS with sodium phenylbutyrate and approved as Relyvrio in 2022, but the larger phase 3 (PHOENIX) found no benefit and the drug was withdrawn in 2024 — a clean example of a small-trial result not surviving.
Commonly used: 250-1,500 mg per day
No authority has set a ceiling. Trials have used 250-1,750 mg/day.
