Their mechanisms include inhibiting MDM2-p53 interaction, modulating the MAPK pathway, and suppressing NF-κB activity. Urolithin A's antiaging activity is linked to activating mitophagy and mitochondrial biogenesis. A clinical trial showed urolithin A is safe up to 2,500 mg/day and improves mitochondrial biomarkers in elderly patients. ## Conclusion Urolithins, particularly urolithin A, show promise as therapeutic agents due to their diverse biological activities and involvement in key cellular mechanisms, including mitophagy and mitochondrial biogenesis. Further clinical research is warranted. ## Limitations The abstract does not explicitly state limitations of the reviewed studies or the review itself, but it emphasizes the need for further clinical trials. ## Verbatim from the abstract > urolithin A is safe and can improve mitochondrial biomarkers in elderly patients ## Where this study is used on Magellan This paper is one of the citations behind the evidence grade on the pages below.
