Bile acid with proven liver-protective and neuroprotective effects. Essential on oral steroid cycles.

How TUDCA (Tauroursodeoxycholic Acid) works

Replaces cytotoxic hydrophobic bile acids in the bile acid pool, reducing hepatocyte endoplasmic reticulum stress and mitochondrial dysfunction. Activates UPR (unfolded protein response) and NF-kB protective pathways. Also protects retinal and neuronal cells.

TUDCA (Tauroursodeoxycholic Acid) interactions

  • with Methylated Orals

    Compatible

    TUDCA reduces ALT/AST elevation from 17α-methylated orals (Anavar, Winstrol, Dianabol) by supporting bile acid flow.

    Timing: TUDCA 500mg daily during oral steroid cycles

  • with NAC

    Compatible

    NAC supports glutathione/liver detox while TUDCA addresses bile flow — non-overlapping hepatoprotective mechanisms.
