L2 已蒐集 4 篇 2023-2025 MA(含 41 RCT/3,759 人 RA pain SMD -0.42、OA pain SMD -0.29),方向一致且效果中等,搭配 Examine Grade B、NIH ODS 明確列為 RA adjunctive 支持、Arthritis Foundation 給具體 2.6 g 劑量建議,足以支撐 B 級『初步至中度證據、學會 conditional / 多 MAs 支持但異質性高』。
但 RA 在 ESR/CRP/DAS28 等發炎活動指標仍未達顯著、2025 SR 子群 I²=80%、OA 證據強度低於 RA、Mayo/Harvard/Cleveland 三大美國機構口吻偏 cautious('might / may help / 補充劑證據不足'),整體未達 A 的『多國學會 first-line + ≥1 quality MA + ≥3 一致 RCT 強一致』門檻。

低中高
📍立場總覽
PTT 多數使用者反映魚油對類風濕關節炎/發炎需高劑量、長期服用半年以上才有感,常推薦高濃度 EPA(>70%) rTG 型態;提醒空腹易腸胃不適,整體業配密度低。
💬社群實感
多數正面(但須長期高劑量)
破解迷思 社群最常見的 4 個誤解
✓
事實誤以為魚油可取代醫師處方治療類風濕關節炎
✓
事實誤以為所有魚油濃度/型態效果相同(rTG > EE,高 EPA 濃度才有抗發炎效果)
✓
事實誤以為植物性 ALA 魚油等同魚源 EPA/DHA(轉換率極低)
✓
事實短期一兩週吃就期待見效(實需長期服用半年以上)
🩹 社群通報的副作用
- 空腹服用造成腸胃不適/腹瀉('烙賽')
- 魚腥味打嗝/反胃
- 高劑量無感(劑量不足者)
