White Kidney Bean, Oral Glucose Tolerance Test
Brief summary
The goal of this randomized, double-blind, cross-over inverventional study is to evaluate the efficacy of white kidney bean on OGTT (oral glucose tolerance test). About 34 eligible participants will be randomized in two groups of the same size to take the assigned interventions at one study site in Shanghai, two visits will be required. The first group of participants will take Wonderlab product first and then placebo product after 72 hours of washout period, while the other group of of participants will take placebo product first and then Wonderlab product after 72 hours of washout period. For each visit, the finger blood will be sampled and the relevent data such as blood glucose will be captured based on OGTT procedures, and recorded into clinical data management system for statistical analysis. Researchers will compare the two groups to see if there is significant change of blood glucose by using products containing ingredient of white kidney beans.
