牛磺熊去氧膽酸 TUDCA × 非酒精性脂肪肝
The totality of evidence is insufficient to grade TUDCA for NAFLD/MASLD on any meaningful clinical endpoint.
The totality of evidence is insufficient to grade TUDCA for NAFLD/MASLD on any meaningful clinical endpoint. There is no completed human trial testing TUDCA against NAFLD histology, liver fat imaging, or fibrosis. The single relevant human RCT (Kars 2010, n=20, 4 weeks) measured hepatic and muscle insulin sensitivity, which is a surrogate for insulin resistance rather than a NAFLD outcome, and it found no change in ER stress markers, undercutting the proposed chemical-chaperone mechanism in humans. All NAFLD-specific efficacy data (steatosis, fibrosis, gut-liver axis) come from mouse models. No regulator (FDA, EFSA, NHS, TFDA, WHO) and no clinical institution or professional society (Mayo, Cleveland Clinic, Harvard, AASLD, AGA) endorses TUDCA for NAFLD, and the closely related parent compound UDCA explicitly failed to show histological benefit in NASH RCTs. Examine's C grade rests on a fuzzy-mapped Obesity 'Liver Cell Content' row (1 study, n=5) that is not a NAFLD endpoint, so a C grade overstates the directly applicable evidence; U is the honest grade.
評分透明度
所有分數由 7 層證據引擎計算，過程公開可查▸查看完整決策路徑（audit trail）
- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.455
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 無高階證據可裁決
- tier_strict_requirement_check — | C→U 因 scope.conflation_risk=true 且 L11 獨評較低 (B7-2 tier cap)
- detect_disputes — 偵測到 1 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
牛磺熊去氧膽酸（TUDCA）在台灣 PTT/Dcard/Mobile01/痞客邦針對非酒精性脂肪肝幾乎無真實使用者討論；脂肪肝相關討論多聚焦飲食運動或處方 UDCA（如膽維他/利福），TUDCA 能見度集中於 iHerb 代購與賣場頁面。
無共識（台灣社群幾乎無針對 NAFLD 的 TUDCA 實測心得，現有討論多為一般脂肪肝飲食運動或處方熊去氧膽酸 UDCA，非 TUDCA 補劑）
- 減重（飲食調整與運動）
- 地中海飲食型態
- 減少或戒除酒精
