穀胱甘肽 Glutathione × 肝臟健康
Human evidence for ORAL glutathione for general liver health does not reach the threshold of any controlled-evidence grade.
Human evidence for ORAL glutathione for general liver health does not reach the threshold of any controlled-evidence grade. The only positive signals come from small, open-label, single-arm, uncontrolled NAFLD pilots (a 2017 n=34 pilot and a 2025 literature review of 3 studies totaling 109 participants) showing an ALT trend that cannot be separated from the concurrent lifestyle intervention or natural disease course. The single double-blind RCT (2020, cirrhosis, n=61, oral glutathione 500 mg/day) found NO significant effect on oxidative stress or antioxidant capacity. Examine has no liver outcome entry for glutathione at all (L1 coverage gap), and no major institution endorses it: AASLD and AGA do not mention oral glutathione in NAFLD/MASLD guidance, and Mayo, Cleveland Clinic and Harvard publish no supplement recommendation. The precursor NAC has genuine evidence in acute liver failure, but that is a different intervention and route and must not be conflated. With no adequate controlled human evidence supporting efficacy, the honest grade is U.
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 — 高品質 SR/MA 顯示 positive (1 篇 > 0 negative)
- 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 0 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群對穀胱甘肽的討論量大，但幾乎集中在「美白淡斑」（PTT BeautySalon、Dcard 美妝版），主流經驗偏向質疑或無共識（多人「無感+1」「完全沒效」，少數覺得淡斑有感）。針對「肝臟健康／護肝」的討論極少出自真實鄉民實測，多半出現在 vocus、嚴萃、痞客邦等業配型「護肝保健品推薦」清單文中，業配密度高。科普方/反業配者反覆強調口服穀胱甘肽會被胃酸與蛋白酶分解、生物利用度低於 1%，因此護肝功效存疑。整體屬 anecdotal，不構成研究證據。
無共識（護肝面向幾乎無真實鄉民實測；現有討論集中於美白，且美白經驗分歧偏負面）
- 腸胃過敏不適（腹痛、腹瀉、噁心嘔吐）
- 皮膚紅腫、發癢
- 部分人反映吃了反而冒痘
