Brief summary
This is a mechanistic, single-center, double-blind, placebo- and active-controlled, three-time-period, crossover study to evaluate the effect of sprinkled format REDUCOSE compared to placebo (double-blind; confirmative) and active control (open-label; acarbose - explorative) on post prandial glycemia in Asian patients with type 2 diabetes.
Interventions
2 G powder sprinkle containing 250 mg REDUCOSE (mulberry leaf extract - 250 mg - 5% DNJ) + fiber, vitamin D, and chromium picolinate
A placebo matching to the test product will be used as control
Acarbose 100 mg tablet (provided in open-label format)
