TUDCA Reduces ER Stress and Reverses Hepatic Insulin Resistance
Science (2006)
Reversed ER stress, restored insulin signaling, normalized glucose in obese insulin-resistant mice.

TUDCA (Tauroursodeoxycholic Acid)TUDCA (Tauroursodeoxycholic Acid)
Taurine conjugate of UDCA with greater cytoprotection and bioavailability. Uniquely functions as an ER stress inhibitor (chemical chaperone) with demonstrated neuroprotective and insulin-sensitizing effects beyond liver protection.
Potent ER stress inhibition (unique)
Greater hepatocyte protection than UDCA
Insulin sensitization via ER stress reduction
Neuroprotective across multiple models

How it works
Mechanism of action
Shares UDCA mechanisms plus potent chemical chaperone activity, stabilizes misfolded proteins, facilitates proper folding, and attenuates the unfolded protein response (UPR). Reduces ER stress which drives T2DM, neurodegeneration, and NASH.
