Urolithin A and Endothelial and Cerebrovascular Function in Middle-Aged Adults With Obesity: A Randomized Clinical Trial

Importance: Midlife obesity affects nearly half of US adults and is a major risk factor for chronic diseases. Mitochondrial dysfunction contributes to obesity-related endothelial dysfunction and disease risk, highlighting the mitochondria as a potential intervention target. Urolithin A (UA), a polyphenol-derived microbial metabolite and mitophagy activator, is safe and benefits mitochondrial health in humans.
