Urolithin A Supplementation in Middle-aged Adults With Obesity

Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to learn about the effect of urolithin A, a dietary supplement, on blood flow in middle-aged adults with obesity. The main question it aims to answer is: - Does urolithin A supplementation improve blood flow in large and small blood vessels in middle-aged adults with obesity? Participants will be asked to: - Take the dietary supplement daily for 4 weeks - Attend two study visits to have their blood vessels checked, answer questionnaires, and give a sample of blood Researchers will compare people who took the dietary supplement with others who took a placebo to see if the blood flow in the blood vessels improved.

Clinical Trial Description

This study aims to measure the effect of urolithin A supplementation on endothelial function, cerebral blood flow regulation, and serum biomarkers of NO bioavailability and mitochondrial function in middle-aged adults with obesity. Briefly, 54 adults aged 40-64 years of age with a body mass index equal to or greater than 30 kg/m2 will be recruited to participate in a double-blind placebo-controlled parallel study for 4 weeks. Participants will be randomly assigned to intervention or control group. Those in the intervention group will consume 1,000 mg of urolithin A daily in the form of softgel capsules, whereas those in the control group will consume a placebo. Data collection will occur at baseline (day 0) and endpoint (day 28). The investigators will compare outcomes between control and intervention group. Researchers expect that urolithin A supplementation in middle-aged adults with obesity improves endothelial function and cerebral blood flow regulation, and that this improvement is accompanied by changes in biomarkers of NO bioavailability and mitochondrial function. ;
