- Clinical Evidence: A randomized, double-blind, placebo-controlled clinical trial conducted on elderly and middle-aged participants showed that daily supplementation with urolithin A led to statistically significant improvements in muscle endurance, grip strength, and 6-minute walking distance.

Anti-Inflammatory and Neuroprotective Effects
- Mechanism of Action: It downregulates the expression of systemic inflammatory factors such as TNF-α and IL-6, and protects neurons from oxidative stress damage.
- Research Evidence: Preclinical and translational clinical studies indicate that urolithin A helps alleviate age-related chronic low-grade inflammation, also known as inflammaging, and exerts positive effects on long-term cognitive function and brain health.
