What is green tea extract studying for blood sugar regulation?

Green tea extract is being studied to see how it affects blood sugar levels in adults with elevated fasting glucose. Researchers want to understand if this supplement can help manage blood sugar and related metabolic factors. The study is sponsored by Amorepacific Corporation and uses a controlled trial design for accurate evaluation.

Who may be eligible for this blood sugar clinical trial?

Adults aged 19 to 64 years with a body mass index between 18.5 and 29.9 kg/m² and fasting blood glucose levels between 100 and 139 mg/dL may be eligible. Both males and females can participate. People currently on blood glucose medications or with certain health conditions may not qualify. Please review eligibility criteria for more details.

Is there any cost to participate in this blood sugar clinical trial?

Study-related care, including the study supplement and all trial visits, is provided at no cost. However, personal travel and other expenses may vary and are not guaranteed to be covered. Participants should plan accordingly for any costs related to attending study visits.

What this Trial Is About

Researchers are evaluating the effects and safety of green tea extract on blood sugar regulation. This 12-week study uses a randomized, double-blind, placebo-controlled design to compare green tea extract tablets with placebo tablets in adults aged 19 to 64 years who have elevated fasting blood glucose levels. The study aims to see if green tea extract can reduce blood glucose levels and affect related metabolic indicators. Participants will be randomly assigned to take either three green tea extract tablets or three placebo tablets once daily for 12 weeks. The study groups receive their assigned tablets orally each day during this period. The design ensures that neither participants nor researchers know who receives the active supplement or placebo until the study concludes. During the study, participants will have their fasting glucose levels measured at the start and after 12 weeks. Researchers will also assess lipid metabolism markers, oral glucose tolerance tests, blood biomarkers, and waist circumference at these times. This includes safety monitoring and evaluation of any changes in these health measures over the study period. The total participation time is 12 weeks.
