桑葉萃取物 Mulberry Leaf Extract × 減重 / 體脂下降
結論：證據支持
桑葉／DNJ × 減重屬 C 級薄弱證據：機轉合理（DNJ 為 α-glucosidase 抑制劑，降低升糖負荷）且有少量人體研究與動物正向訊號，但無任何以體重／BMI／腰圍／體脂為主要終點之人體 RCT 或 MA（L2 0.

桑葉／DNJ × 減重屬 C 級薄弱證據：機轉合理（DNJ 為 α-glucosidase 抑制劑，降低升糖負荷）且有少量人體研究與動物正向訊號，但無任何以體重／BMI／腰圍／體脂為主要終點之人體 RCT 或 MA（L2 0.35）；現有人體試驗均以餐後血糖／胰島素／血脂為主，體重僅為入組條件或描述性次要指標。
減重訊號主要來自 DNJ 高脂飲食小鼠模型（內臟脂肪下降、adiponectin 上升），屬間接證據。
非 U 級（並非全無人體研究與機轉），但遠不及 B 級（無方向一致之小型減重 RCT）。

Mulberry-extract improves glucose tolerance and decreases insulin concentrations in normoglycaemic adults
結論：Single-dose mulberry leaf extract reduced postprandial glucose AUC (~22% at higher dose) and insulin AUC (~24.7%) vs placebo. Body weight/BMI was an inclusion criterion (BMI 20-30) but NOT a measured outcome; no anthropometric endpoint reported.

Effects of Mulberry Leaf Extract Rich in 1-Deoxynojirimycin on Blood Lipid Profiles in Humans
結論：Modest decrease in serum triglyceride and beneficial lipoprotein changes after 12 weeks. Body weight and BMI were tracked descriptively but not designated primary outcomes; no significant weight reduction reported in this hypertriglyceridemic cohort.

A meta-analysis of efficacy of Morus alba Linn. to improve blood glucose and lipid profile
結論：Morus alba significantly improved postprandial glycaemia and lipid markers. The pooled analysis did NOT include body weight, BMI, waist circumference, or body fat as outcomes; weight loss endpoints were not extractable from included trials.

Intake of mulberry 1-deoxynojirimycin prevents diet-induced obesity through increases in adiponectin in mice
結論：DNJ decreased visceral fat weight and adipocyte size and increased serum adiponectin in HFD mice. Animal-only evidence; no human extrapolation possible.

A cause and effect relationship cannot be established between the consumption of Morus alba (white mulberry) leaf extract and the claimed effect. The mulberry extract is not sufficiently characterised in relation to the claimed effect. The proposed target population of diabetic patients does not comply with the criteria for disease risk reduction claims. 來源↗

Several studies suggest that white mulberry may reduce elevated blood glucose levels, but some of these studies have been preliminary or were not conducted in humans. Other trials have found no effect on blood glucose levels. There is a potential risk for low blood sugar when taken with diabetes medications. 來源↗

📍立場總覽
台灣社群針對桑葉萃取物「減重/體脂」的直接討論稀少。健身板（MuscleBeach）鄉民對控糖控脂保健品普遍質疑、視為智商稅，認為頂多輔助餐後血糖、對減脂無實質效果。消費端主要為太田胃散 DNJ 順暢桑葉茶，但討論集中在排便順暢而非減脂，且多為業配/部落格推薦文，可信社群實測極少。
💬社群實感
減脂效果無共識且多數負面（健身社群視為智商稅）；正面心得多集中在『排便順暢、肚子變平』而非真正體脂下降，且來源多為業配文
破解迷思 社群最常見的 4 個誤解
✓
事實把桑葉茶當成『減肥茶／燃脂茶』，但其實 DNJ 機制是延緩醣類吸收、降餐後血糖，不直接燃脂或減少總熱量
✓
事實誤以為『排便順暢、宿便排出、肚子變小』等於減脂，多為利尿排便造成的暫時體重變化而非體脂下降
✓
事實誤以為單靠桑葉萃取就能減重，忽略仍須熱量赤字、飲食控制與運動
✓
事實誤以為日本藥妝『餐前控糖／控脂』保健品（含桑葉、阿拉伯糖、甲殼素）能顯著減脂，鄉民實測多認為效果微乎其微
🩹 社群通報的副作用
- 脹氣／胃部不適
- 腹瀉
- 頭暈（過量或敏感體質）
- 與降血糖藥併用恐使血糖過低
🏷️ 社群熱議品牌
依論壇被提及頻率，非銷售或品質排序。
- 太田胃散 DNJ速纖順暢桑葉茶（最常被提及，但偏整腸/排便定位）
- Reducose®（NUTRISENSE 生資、realpromise 等通路採用的專利桑葉萃取原料，多見於業配/廠商文）
