Study summary

This project will test a unique botanical formula designed to inhibit alpha amylase (the primary starch degrading digestive enzyme) and inhibit sucrase (the primary sucrose degrading digestive enzyme) in order to reduce acute post prandial glycemia regardless of nutritive carbohydrate source.

Read the detailed description

Type 2 diabetes is a metabolic disorder characterized by elevated fasting blood glucose and impaired insulin signaling (insulin resistance) and is associated with several comorbidities including neuropathy, retinopathy, kidney disease, and elevated risk for heart attack and stroke. Lifestyle interventions targeted towards prevention of type 2 diabetes include: maintaining and achieving healthy bodyweight, physical activity, avoiding tobacco use, and reducing sugar and saturated fat intake. The International Scientific Consensus Summit from the International Carbohydrate Quality Consortium indicated that diets low in glycemic index and glycemic load were important in the prevention and management of diabetes. Health supplements that can lower the glycemic index and glycemic load of food have potential to support the prevention of diabetes and improve blood glucose management by reducing post prandial glycemia and insulinemia. This project will test a unique botanical formula designed to inhibit alpha amylase (the primary starch degrading digestive enzyme) and inhibit sucrase (the primary sucrose degrading digestive enzyme) in order to reduce acute post prandial glycemia regardless of nutritive carbohydrate source. This proposal will fill a void in the literature by testing for the first time the effect of a combination of mulberry leaf, white kidney bean extract and cinnamon on postprandial carbohydrate absorption and glucose control in overweight, insulin resistant men and women. This project will provide pilot data to support larger studies, and studies to investigate long-term effects.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2019; primary completion for Nov 2019, 3 months later.

Of 225 interventional studies with no phase under Hyperglycemia, half reached primary completion within 14 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 27. This study's planned 3 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 28, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
