Effect of Mulberry Leaf Extract on Blood Glucose
Effect of Mulberry Leaf Extract on Blood Glucose in Subjects With Impaired Fasting Glucose

The purpose of this study is to evaluate the effect of mulberry leaf extract on blood glucose in subjects with impaired fasting glucose.

The purpose of this study is to evaluate the effect of mulberry leaf extract on blood glucose in subjects with impaired fasting glucose. After 2 weeks run-in period for wash-out, subjects will randomly assigned to two groups, i.e. control group (placebo) or mulberry leaf extract group. They will intake placebo or mulberry leaf extract for 4 weeks. Biomarkers will be analyzed in blood samples in 0 and 4 weeks.
