What does the research say about Urolithin A?

strong evidence

Urolithin A is one of the most rigorously researched longevity ingredients of the last decade. The Mitopure form is the only commercially-available source with published RCTs.

Best-evidenced use cases
  • Mitophagy support in adults 40+
  • Muscle endurance preservation
  • Older adults with declining physical function
  • Recovery in active populations

How we read the research

We prioritize randomised controlled trials and meta-analyses over single observational studies. Animal and in-vitro data are listed as "mechanistic", they suggest direction, not human effect size.

What we don't do

We don't cherry-pick favourable studies, omit conflicting evidence, or cite industry-funded trials without flagging the conflict of interest where known.

The research is one thing, what to take, at what dose, paired with what, is another. We compose stacks that turn the evidence into a daily routine.
