TUDCA: The Ultimate Driver of Clean Arteries
In a Nutshell
TUDCA, a gut-derived bile acid supplement, dramatically reduces atherosclerosis plaque formation in animal models of high-fat/high-sugar diets by suppressing ER stress, ATF4 activation, and inflammasome signaling in artery walls—improving macrophage cholesterol efflux without altering cholesterol levels. This interrupts the inflammatory cascade turning macrophages into dysfunctional foam cells, offering a promising alternative or statin adjunct (countering statins' reduction of UDCA/GLP-1). Evidence-based dosing starts at 250mg/day with food, titrating to 1,750mg split 2-3x daily; well-tolerated but lacks human RCTs due to low profit incentive.

A hormone and trending supplement made by your gut, TUDCA, has the potential to slow or maybe even stop atherosclerosis, the buildup of fatty plaques in arteries that can lead to heart attack, stroke, and death. TUDCA is a bile acid that fights heart disease not by lowering cholesterol, but by altering inflammatory pathways, the inflammatory foundation that drives plaque formation in arteries. As a supplement skeptic, this one might live up to the hype. We'll unfold the data, introduce key players, and explore how your gut controls your heart. It's not a miracle but a compelling signal. TUDCA dramatically reduces plaque formation, supports gut health, liver function, mitochondrial function, and maybe even neuroprotection.

Animals were fed a high-fat, high-sugar Western-style diet designed to induce heart disease, atherosclerosis. One group received TUDCA, dramatically reducing plaque formation.

TUDCA (tauroursodeoxycholic acid) is a bile acid made by the gut or taken as a supplement that circulates throughout the body as a hormone with broad metabolic effects. Popular in metabolic health for supporting gut health, liver function, mitochondrial function, and maybe neuroprotection. Focus here is on cardiovascular health.
