C 🟠 C 薄弱證據 附警語發布 🚨 high — heavy affiliate marketing in TW community
LcS（代田株）對 H. pylori 的 strain-exact 人體證據極為薄弱：僅一篇 2003 年小型試驗（n=14 介入組）顯示 urease 活性下降趨勢但未達統計顯著（P=0.22），加上一篇 in vitro/動物研究。
所有「支持益生菌輔助 H. pylori 根除」的 meta-analysis（2019 NMA, 2024 umbrella review）皆為 species-/generic-level 證據，未單獨分析 LcS，且 umbrella review 指出 Bifidobacterium 才是潛力最高之菌屬。
ACG 2024 指引明確聲明證據不足以支持 probiotics（含 LcS 在內）輔助 H. pylori 根除，Mayo / Cleveland / Harvard 亦無 LcS × H. pylori 立場；台灣 TFDA 健字號僅核准胃腸功能改善/免疫調節，非 H. pylori 適應症。
整體屬「弱證據 + 多為通用屬層級代理」，給予 C 級。

Probiotics are live microorganisms which when administered in adequate amounts confer a health benefit on the host. The 2002 FAO/WHO Working Group Guidelines for the Evaluation of Probiotics in Food require strain-level identification (genus, species, strain), in vitro testing (acid/bile tolerance), safety assessment (antibiotic resistance, metabolic activities, no transferable resistance), and… 來源↗

📍立場總覽
台灣 PTT、Dcard、Mobile01 等社群中，幾乎找不到專門針對「養樂多代田株 LcS」對抗幽門螺旋桿菌的個人經驗分享。多數討論為通用「益生菌輔助三合一療法」的衛教轉述，或將養樂多歸類於整腸/便秘用途，並非菌株特異性的幽門桿菌療效心得。
💬社群實感
資料不足
破解迷思 社群最常見的 4 個誤解
✓
事實誤以為長期喝養樂多即可預防或殺死幽門螺旋桿菌
✓
事實把養樂多代田株與一般「乳酸菌」混為一談，忽略菌株差異
✓
事實認為發酵乳活菌數越高就越能對抗幽門桿菌
✓
事實誤信網路文章「大蒜、蜂蜜、益生菌能殺死幽門桿菌」的單方說法
🩹 社群通報的副作用
- 資料不足，社群偶提到含糖量高、糖尿病或減重者需注意
