•📚 Key Scientific Studies on Mulberry Leaf (Morus alba)
🧪 1. Human Clinical Trial (Strong Evidence)
“Mulberry leaf extract improves glycaemic response…” (2021)
Type: Randomized, double-blind, placebo-controlled study
Findings:
Significantly reduced blood glucose and insulin spikes after sugar intake
Up to ~40% reduction in peak glucose levels
👉 Conclusion: Mulberry leaf extract may help support healthy blood sugar response after meals.

🧪 2. Clinical Study on Pre-Diabetic Subjects
“Effect of mulberry leaf extract with DNJ…”
Type: Human clinical trial (short-term + 12-week study)
Findings:
Reduced post-meal blood sugar levels
Showed improvement in glycemic control over time
👉 Mechanism linked to DNJ (active compound)

🧪 3. Randomized Controlled Trial (Obese / Borderline Diabetes)
Dose-finding study on mulberry leaves (Thailand)
Findings:
Reduced fasting blood glucose
Lowered HbA1c (long-term sugar marker)
Improved insulin response
👉 Supports metabolic health benefits
