# Urolithin A Muscle Endurance in Adults

## Signal

Urolithin A improved muscle strength, aerobic endurance, and physical performance in middle-aged adults. [R1]

## Update

In older adults, urolithin A did not significantly improve 6-minute walk distance or maximal ATP production, but it improved FDI and TA muscle endurance. [R2]

## Synthesis

Across these trials, urolithin A improved multiple performance outcomes in middle-aged adults; in older adults, primary walk and ATP endpoints were null while muscle endurance improved. Because the cohorts and endpoints differed, this does not establish an age effect. [R1] [R2]

## Falsifier

Use an age-stratified randomized trial with the same 6-minute walk, ATP, and muscle-endurance endpoints to test whether this endpoint-specific pattern persists. [R1] [R2]

## Receipts
- [R1] Urolithin A improves muscle strength, exercise performance, and biomarkers of mitochondrial health in a randomized trial in middle-aged adults (2022). DOI: 10.1016/j.xcrm.2022.100633.
- [R2] Effect of Urolithin A Supplementation on Muscle Endurance and Mitochondrial Health in Older Adults: A Randomized Clinical Trial. (2022). DOI: 10.1001/jamanetworkopen.2021.44279.

## Status

Challenger output. Every factual claim is receipt-bound; the falsifier is a proposal, not evidence.
