Plain English Summary

Background and study aims
The amount of sugar (glucose) in the blood is controlled by a hormone called insulin. If you have diabetes, either the body does not produce enough insulin or the insulin produced doesn't work properly, leading to high blood glucose levels. Extracts of the Salacia species of herb from roots, stems, and leaves are used for the treatment of diabetes in Asia. The aim of this study is to examine the effect of different doses of a new form of Salacia extract (Salacia Chinensis, SCE) on the glucose and insulin response to oral sucrose (sugar) solution in healthy individuals (South Asian Population).

Who can participate?
People aged 18-55, with body mass index (BMI) 24.5 to 29.5 kg/m2

What does the study involve?
Participants are given sucrose solution and Salacia extract, and blood samples are collected at the start and after 30, 60, 90, 120 and 180 minutes to assess their blood glucose and insulin response. Different doses of Salacia extract are tested with a 7-day break in between treatments and results are compared with a placebo (dummy) treatment.

What are the possible benefits and risks of participating?
We will find out whether Salacia supplementation helps to maintain or lower blood glucose and insulin levels after sucrose solution administration. This will help them to understand how to manage blood glucose levels and helps in diabetes condition. Pain associated due to multiple times of blood collection to assess blood glucose and insulin levels.

Where is the study run from?
Semler Research Center (India)

When is the study starting and how long is it expected to run for?
July to December 2015

Study information

Scientific title

Salacia extract improves post-prandial glucose and insulin response: a randomized double-blind placebo-controlled, cross-over study in healthy volunteers


Study hypothesis

Studies indicate that Salacia extracts modulate multiple targets that influence carbohydrate and lipid metabolism. This study is to examine the effect of differing doses of a novel form of Salacia extract (Salacia Chinensis, SCE) on glucose and insulin response to an oral sucrose load in healthy individuals (South Asian Population).

Participants will be randomly assigned to ingest Salacia extract at dosages of 200 mg SCE , 300 mg SCE and 500 mg SCE (OmniLeanTM) or placebo (PLA) in a single-center, double-blind, randomized, placebo-controlled four-way cross-over design. Washout period between treatment periods was 7 days. Plasma glucose and plasma insulin responses after 0, 30, 60, 90, 120, 180 min of ingesting oral sucrose standard solution and area under curve for glucose (AUCglucose) and insulin response (AUCinsulin) will be calculated. ANOVA and paired t-tests will be used to examine differences between treatments and over baseline.
