# Urolithin A Endurance Efficacy

## Signal

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

## Update

Urolithin A failed to significantly improve 6-minute walk distance and maximal ATP production in adults aged 65 to 90. [R2]

## Synthesis

Efficacy varies by age cohort, with benefits observed in middle-aged adults but absent for primary endurance and ATP endpoints in older adults. [R1] [R2]

## Falsifier

Compare 6-minute walk distance improvements between a middle-aged cohort and a cohort aged 65-90. [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.
