Mulberry-extract improves glucose tolerance and decreases insulin concentrations in normoglycaemic adults
PMID: 28225835 2017 RCT (double-blind) n = 37
結論：Mulberry extract significantly reduced postprandial glucose iAUC by 42% and insulin iAUC by 41% vs placebo (p<0.001) in normoglycaemic adults.

A mulberry leaf extract inhibits sucrase activity and suppresses postprandial blood glucose response
PMID: 21480801 2011 RCT (double-blind) n = 50
結論：Mulberry leaf extract significantly suppressed postprandial glucose and insulin elevation after sucrose load vs placebo (p<0.05), consistent with alpha-glucosidase inhibition.

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

PTT（regimen/FITNESS/Health）、Dcard 與 Mobile01 對「控血糖保健品」討論熱絡，但鄉民實際推的多是苦瓜胜肽、肉桂、鉻等，桑葉萃取物幾乎沒有針對第二型糖尿病的原生實測討論。桑葉×血糖內容幾乎全集中在商業健康媒體（健康2.0/TVBS、ETtoday）與品牌業配 SEO 文（悠活原力、NutriSense、Reducose 廠商、pure-au「PTT 懶人包」導購），且 MyGoPen 已查核闢謠（人體證據不足、衛福部核准適應症不含降血糖）。屬冷門題、業配污染高，社群無真實共識。

💬社群實感

無共識（針對桑葉萃取物治第二型糖尿病的鄉民原生實測心得極少，幾乎查無真實使用回饋）

破解迷思 社群最常見的 5 個誤解
✓
事實誤以為喝桑葉水／吃桑葉錠可取代糖尿病處方藥控糖（營養師臨床指有患者停藥猛喝反使血糖升高）
✓
事實把『桑葉茶』與『標準化桑葉萃取物（如 Reducose）』功效混為一談，但兩者 DNJ 含量與作用差異大
✓
事實誤以為桑葉降血糖已有充足人體證據（MyGoPen 查核：研究多停在動物實驗，衛福部核准適應症為解熱、頭痛、口渴、咳嗽，不含降血糖）
✓
事實誤以為桑葉 DNJ 為長效，整天喝就能壓血糖（DNJ 作用僅約 4-6 小時，非長效）
✓
事實誤以為桑葉性溫可天天當水猛喝（桑葉性寒，過量易腸胃不適、腹瀉）
🩹 社群通報的副作用
  • 桑葉性寒、過量飲用致腸胃不適／腹瀉（多見於商業媒體與營養師警語，非社群實測）
