TUDCA: The Ultimate Driver of Clean Arteries

Описание: For added nuance and all the references, see the letter: https://staycuriousmetabolism.substac...

Description:
A gut-made hormone (and trending supplement) called TUDCA may reduce plaque formation in atherosclerosis—not by lowering cholesterol, but by changing the inflammatory biology that drives plaque growth in the first place.

In this video, we walk through the data step-by-step: the key molecular players (ER stress → ATF4 → inflammasome), how a Western-style diet can trigger this cascade, and why TUDCA appears to interrupt it—quieting inflammatory signaling and improving macrophage “cholesterol efflux” (the ability to clear cholesterol out of artery walls).

Important caveat: the main plaque findings are preclinical (animal), and we do not yet have large human RCTs showing TUDCA slows or reverses atherosclerosis. Still, the mechanism is compelling, and it connects to a fascinating thread: statins, gut bile acids (UDCA/TUDCA), and GLP-1 biology.
