Summary
This study tests whether urolithin A, a natural supplement, can improve how the body releases insulin and controls blood sugar in healthy adults aged 55 and older with a BMI of 27 or higher. Over 8 weeks, 180 participants will take either urolithin A or a placebo daily. Researchers will measure insulin and hormone responses to sugar drinks, continuous glucose monitoring, and exercise tests.
