Efficacy of Glucosanol™ in Reducing Post-prandial Glucose Levels in Overweight Subjects

Double-blind, Randomised, Placebo-controlled, 3-way Cross-over Study to Evaluate the Benefit of Two Glucosanol™ Dosages to Reduce Post-prandial Glucose Levels in Overweight Subjects

Glucosanol had previously been proven to be effective in aiding weight loss and weight loss maintenance. Studies have also shown that Glucosanol (also known as Phaseolamin), was effective in aiding weight loss and also has evidence on reducing post-prandial glucose levels. This study is to enrich the existing evidence on dose-dependent post-prandial glucose effects of Glucosanol
