NCT ID NCT07377097
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how artificial sweeteners (saccharin, sucralose) and a natural one (erythritol) affect blood sugar control, blood clotting, and heart disease risk in 80 adults with prediabetes. Participants will be randomly assigned to take one sweetener or water for two weeks. Researchers will measure changes in glucose tolerance, gut bacteria, and immune cells to see if these sweeteners might be harmful.
