S-腺苷甲硫胺酸 SAMe × 憂鬱症
SAMe for depression has a genuine but limited evidence base.
SAMe for depression has a genuine but limited evidence base. The largest 2024 meta-analysis (23 trials, n=2183) found SAMe monotherapy significantly superior to placebo (SMD -0.58), and this is corroborated by Examine's grade B (11 studies, 1558 participants, small improvement). However, the same meta-analysis found no benefit as an adjunct or head-to-head versus antidepressants, a second 2024 meta-analysis found no significant difference in any comparison, the rigorous 2018 adjunctive RCT (n=107, 800 mg/day) was negative (p=0.51), and the 2016 Cochrane review rated the overall evidence very-low to low quality. Trials are heterogeneous (I2 up to 68%), dosing varies enormously (200-3200 mg/day), and many are old and small with unclear risk of bias. The APA guideline describes only modest evidence and NCCIH concludes research has not conclusively shown benefit, so a grade higher than B is not warranted; a grade B with explicit caveats is the honest, evidence-proportionate call.
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 = 0.491
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高階證據未達主導 (0 positive vs 1 negative)，由 raw_score 決定
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 0 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
SAMe 在台灣 PTT/Dcard/Mobile01 幾乎沒有針對憂鬱症的原生第一人稱實測討論，訊號極低。可見資料以藥師部落格（微笑藥師網）、保健文章（營養新知、EVIS）、iHerb 代購與廠商商品頁（SAMe-X、Life Extension）為主，屬商業／衛教內容而非鄉民心得。藥師端反映民眾偶有諮詢，但社群並無實際使用憂鬱症的經驗共識。
無共識（台灣社群針對憂鬱症的原生實測討論稀少，可見內容多為藥師／保健媒體衛教與代購開箱，非鄉民心得）
- 噁心、腹瀉、排氣等腸胃不適（衛教來源，社群第一手回饋稀少）
- 輕度失眠、頭暈、頭痛
- 少數人服用後較為躁動／焦躁（藥師部落格提及，原因不明）
- 與 SSRI 併用之血清素症候群風險（警語層級，非社群實測）
依論壇被提及頻率，非銷售或品質排序。
- Nature Made SAM-e Complete 400mg（美國 Costco 代購最常被提及）
- Life Extension SAMe（iHerb 代購，腸溶錠 200mg）
- NOW Foods／Doctor's Best 等 iHerb 進口腸溶錠
- SAMe-X 酵母發酵物（漢馨科技，台灣少數本地廠商品）
