乙醯左旋肉鹼 Acetyl-L-Carnitine × 神經病變
The evidence does not support a single grade because it splits sharply by neuropathy type.
The evidence does not support a single grade because it splits sharply by neuropathy type. For DIABETIC peripheral neuropathy (DPN), several RCTs and a 2015 meta-analysis (PMID 25751285, n=523) show a modest, dose-dependent pain reduction with the diabetic subgroup outperforming non-diabetic patients, but the most rigorous synthesis, the 2019 Cochrane review (PMID 31201734, n=907), rated certainty of evidence as VERY LOW and the two largest positive trials were industry-sponsored (Sigma-Tau), so the DPN signal is at best weakly positive and uncertain. For CHEMOTHERAPY-induced peripheral neuropathy (CIPN) the evidence is the opposite direction: a high-quality phase-III SWOG/CALGB RCT (PMID 23733756, n=409) found ALCAR significantly WORSENED neuropathy (FACT-NTX 1.8 points worse, p=0.01), and ASCO explicitly recommends against its use for both prevention and treatment of CIPN. Averaging a weakly-positive-but-uncertain DPN signal against a documented-harm CIPN signal yields an honest overall grade of C, with the firm condition that the two indications must never be conflated. Examine independently graded the diabetic-neuropathy outcome C, which aligns with this assessment for the DPN slice only.
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 = 0.448
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (2 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 1 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群幾乎沒有乙醯左旋肉鹼專門用於「神經病變」的鄉民實測。PTT 對 ALCAR 的討論集中在健身板(MuscleBeach)的減脂/抗疲勞與少量補腦/抗老情境，評價偏保守（『我有吃，沒什麼感覺』『輔助效果因人而異』）。「ALCAR 改善糖尿病/周邊神經痛」的中文敘述幾乎全來自保健品 SEO 文、藥師衛教與部落格(痞客邦/vocus/formulawave)，而非匿名社群實測辯證；神經病變適應症並非台灣社群討論主題，屬冷門題目。
無共識（台灣 PTT/Dcard/Mobile01 幾乎無 ALCAR 用於神經病變的在地實測；既有討論集中於減脂/抗疲勞/補腦情境且評價保守，神經病變/糖尿病神經痛的中文內容多為保健品 SEO 與藥師衛教文，非匿名社群真實回饋）
- 血糖控制（強化血糖管理）
- 神經痛藥物（gabapentinoids 與 SNRI）
- 三環抗憂鬱劑（如 amitriptyline）
