This is yeast (1,3)-(1,6)-beta-glucan (e.g. Wellmune, Leiber) for common cold / URTI. A 13-RCT meta-analysis (PMID 33900466) reports a favourable pooled effect on URTI incidence (OR 0.345), episode count and duration, but explicitly flags high heterogeneity and few small trials; the body of evidence is internally inconsistent because the largest and methodologically strongest single RCT (n=299, 2019) found NO reduction in cold incidence or global severity, with only a modest early physical-symptom benefit. The single most damning feature is pervasive conflict of interest: nearly every trial is funded by a beta-glucan manufacturer (Leiber GmbH, Wellmune/Biothera/Kerry) or run by contract research organisations, which inflates the apparent pooled signal. EFSA reviewed exactly these immune and common-cold claims and rejected them twice (2010 Yestimun immune claim, 2013 common-cold claim), citing non-validated cold questionnaires and statistical limitations, and no infectious-disease authority (CDC, IDSA) endorses it while major clinics (Mayo, Cleveland, Harvard) do not address it. I therefore grade C rather than Examine's B: the signal is real but small, manufacturer-funded and inconsistent across the best trials, which warrants a one-notch downgrade for COI and heterogeneity.
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 = 0.449
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (1 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標,未降階
- detect_disputes — 偵測到 0 個 hard + 1 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群幾乎沒有 β-葡聚醣防感冒的真實鄉民實測心得。可見內容多為 PTT 藥師教學文與痞客邦(微笑藥師)專業文,立場理性持平、強調研究結果不一致且運動優先;Mobile01 免疫保健討論串多談 B 群/益生菌/維生素 C、D3,鮮少提到 β-葡聚醣。其餘高排名內容幾乎全是業配導向的健康媒體 SEO 文(推 Wellmune 酵母多醣),業配密度高,社群真實討論訊號極弱。
無共識(缺乏真實鄉民實測心得,可見討論以藥師教學文與業配 SEO 文為主,非個人使用經驗)
- 腸胃不適(脹氣、腹痛、噁心、腹瀉,多見於高劑量;屬資料/藥師提醒,非多人鄉民實際反饋)
依論壇被提及頻率,非銷售或品質排序。
- Wellmune(酵母 β-葡聚醣,業配與專業文中最常被點名,屬市場行銷訊號而非社群共識)
