肌醇 Inositol × 胰島素阻抗
Multiple independent meta-analyses spanning 898 to 2230 participants consistently show inositol reduces HOMA-IR (WMD around -1.
Multiple independent meta-analyses spanning 898 to 2230 participants consistently show inositol reduces HOMA-IR (WMD around -1.21) and fasting insulin (around -4.74 microU/mL), and a 7-RCT pooled analysis found 4 g/day myo-inositol cut gestational diabetes incidence by roughly 70 percent (RR 0.30). This direction-consistent effect across many trials supports more than a C grade. However, three factors hold it back from A: every measured outcome is a surrogate marker (HOMA-IR, fasting insulin, fasting glucose) with no primary clinical insulin-resistance endpoint; the 2024 International PCOS Guideline meta-analysis rated GRADE certainty Very Low and called the evidence limited and inconclusive with no advantage over metformin; and the large NiPPeR RCT (n=1729) found no glycemic benefit when inositol was started preconception in a general population, indicating population and timing strongly modulate the effect. Professional societies (ADA, Endocrine Society) are silent and neither Mayo Clinic nor Harvard maintains an inositol fact sheet, so high-quality independent endorsement is absent. On the totality of evidence a moderate, consistent but surrogate-bound and certainty-limited body of work justifies grade B at its lower bound.
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 = 0.633
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (4 篇 > 0 negative)
- 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
台灣社群討論多集中在多囊/備孕脈絡（胰島素阻抗為其成因），鄉民實測多反映改善排卵與血糖，整體偏正面但屬經驗談，業配品牌推薦文偏多。
多數正面（集中於多囊/備孕族群，反映改善排卵與血糖代謝；非多囊純胰島素阻抗討論較少）
- 腹脹
- 腹瀉
- 腸胃不適（多反映於高劑量或片劑，改粉劑或分次服用可緩解）
