魚油 / Omega-3 Omega-3 / Fish Oil × 代謝功能異常相關脂肪肝病 (MASLD/NAFLD)
結論：證據不足
L2 PubMed 證據顯示多篇 2024-2025 統合分析在生化指標 (AST/GGT、三酸甘油酯、HOMA-IR) 有溫和改善，但對肝脂肪含量 (MRI-PDFF) 與組織學的關鍵肝病終點證據不一致；2025 PMID 40441053 (n=20 RCTs, 1615 人) 顯示僅 GGT 與超音波脂肪有改善且不良事件較多。

AASLD 2023 與 EASL-EASD-EASO 2024 兩大肝病學會均明確不推薦 Omega-3/nutraceuticals 作為 MASLD 治療，僅在共病嚴重高三酸甘油酯時才以調脂用途使用。
患者面 (Mayo/Cleveland/Harvard) 一致採謹慎立場，強調飲食來源優於補充劑。
整體屬「surrogate-only 改善、肝病硬終點不確定、權威指引明確不推薦」，符合 C 級弱證據。

Some research suggests that omega-3 fatty acids may reduce liver fat and may slow or even reverse MASLD scarring. However, other studies haven't found a strong connection between omega-3s and liver inflammation or scarring. Natural sources of omega-3 fatty acids are best. These include fatty fish, such as salmon, mackerel and sardines, walnuts, some seeds, and leafy green vegetables. If you don… 來源↗

謹慎
Mediterranean-style diets can help decrease liver fat, thus helping to prevent or possibly reverse NAFLD. These diets are high in healthful fats, such as monounsaturated fats found in olive oil and avocados, and omega-3 fats found in walnuts and oily fish like salmon and sardines. 來源↗

In adults with MASLD, nutraceuticals cannot be recommended since there is insufficient evidence of their effectiveness in reducing histologically/non-invasively assessed liver damage/fibrosis and liver-related outcomes in MASLD, nor of their safety. 來源↗

TW 社群普遍認為魚油對「合併高血脂的脂肪肝」可能有幫助（主要降三酸甘油酯），但多數人強調減重、戒酒、運動才是真正改善脂肪肝的關鍵，魚油屬輔助性質。重度脂肪肝或服用抗凝血藥物者則被提醒先諮詢醫師。
💬社群實感
意見分歧
破解迷思 社群最常見的 5 個誤解
✓
事實以為吃魚油就可以治療或逆轉脂肪肝（實際上對 NASH 無治療效果，僅可輔助降三酸甘油酯）
✓
事實認為濃度越高越好（忽略 rTG/TG/EE 劑型吸收率差異）
✓
事實把魚油和魚肝油搞混（魚肝油富含維生素 A、D，過量有毒性）
✓
事實誤以為魚油可以取代減重與運動
✓
事實以為所有脂肪肝患者都適合吃魚油（忽略抗凝血藥物交互作用）
🩹 社群通報的副作用
- 魚腥味打嗝、口臭
- 腹瀉、腸胃不適
- 與抗凝血藥併用增加出血風險
- 高劑量可能造成 LDL 微幅上升
