Evidence Summary
Urolithin A is the cleanest evidence story in the supplement space. Timeline/Amazentis has published six human clinical trials showing improved mitochondrial function and muscle endurance. It holds GRAS status, Informed Sport certification, and has the strongest regulatory profile of any longevity supplement.
However, the trials are relatively small (40-100 participants), short-term (4-6 months), and use surrogate biomarkers rather than hard clinical endpoints. No mortality or major morbidity data exists. The C+ grade reflects real but preliminary evidence.

Safety Considerations
Generally well-tolerated. GRAS status. No significant adverse events in published trials. Pregnant/nursing should avoid due to insufficient data.
