The evidence in words
The verdict
For muscle endurance (older adults), Urolithin A earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Early trials
How it might work
It induces mitophagy — the recycling of damaged mitochondria — improving mitochondrial quality in muscle.
How to use it
500–1,000 mg/day.
Safety & cautions
Well tolerated in trials.
Bottom line
A rare longevity ingredient with actual human muscle-function data, if modest. Reasonable to trial for mitochondrial/muscle support.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
- Standard
- 500–1,000 mg/day.
