Study Methodology

The researchers used a randomised double-blind placebo-controlled study, which is a study involving humans in which neither side knows who's getting what treatment and a placebo (an inactive medicine) is given to a control group. The study aimed to investigate the effects of mulberry extract (ME) on glucose tolerance and insulin concentrations in healthy adults, when given 50g maltodextrin. Maltodextrin is a carbohydrate with a high glycemic index (GI) value, which means it can cause a spike in your blood sugar.

Study Findings

The study demonstrated that Mulberry leaf extract (reducose)  substantially reduced the increase in plasma glucose after maltodextrin ingestion over 120 minutes. Total insulin rises were also significantly suppressed over the same period. 

TL;DR

  • 37 adults aged 19 -59 with a 20kg/m2 BMI participated.
  • High sugar and refined carbohydrate intake is associated with weight gain, diabetes, and cardiovascular mortality.
  • Reducose, a mulberry leaf extract (ME), may reduce blood glucose responses after consuming carbohydrates by reducing the absorption of glucose from the gut.
  • Mulberry leaf extracts have shown potential in reducing glucose after meals and insulin levels, decreasing body weight and hepatic lipid accumulation (fatty liver), and enhancing insulin sensitivity, suggesting a potential benefit for weight management.
  • Mulberry leaf extracts have a long history of safe and side-effect-free use, and there were no significant differences in gastrointestinal symptoms between the treatment groups.
  • The study suggests that ME may be a potential target for preventing type 2 diabetes and regulating blood sugars, but more research is needed.
  • Additionally, ME may affect gut microbiota and incretin hormone secretion (gut peptides), further influencing glucose metabolism.
