Urolithin A (Mitopure)

Urolithin A (mitophagy activator). Aging itself. Reviewed Jul 2026.

Randomised trials show modest gains in muscle strength, endurance and immune markers, but there is no lifespan or disease-outcome data.

Stage
Human biomarker trials
Rung: Early human signal. First human or biomarker data. Promising, unproven.
Evidence grade
B
RCTs, function markers
Randomised human data on surrogate markers, or consistent large cohorts. How grades work.

What it is

A postbiotic — the gut metabolite of ellagitannins (pomegranate, walnuts) — sold as Mitopure. It switches on mitophagy, the cellular cleanup that clears damaged mitochondria before they sap energy, muscle and immune function.

The evidence

Randomized human trials at 1,000 mg/day: improved muscle strength and endurance in older adults, lowered markers of cellular senescence, and raised CD8+ T cells and natural killer cells (markers of immune aging); one study reported ~10% greater VO2max gain than exercise alone. Available over-the-counter; no hard lifespan or disease-outcome data yet.

What you can do today

The human evidence is early and does not support a general recommendation. If this area is relevant to you, discuss it with a clinician. Products sold in this space are not proof that it works.

  • Rapamycin for longevityGrade C, strong animal data. Approved drug, off-label use.Extends lifespan across many animal species, but there is no human outcome data for longevity and side effects such as poor wound healing and infection are real.
  • Acarbose for longevityGrade C, strong animal data. Approved drug, off-label use.One of the most reproducible lifespan extenders in mice, mainly in males, but there is no human longevity trial.
  • VO₂max and strength for longevityGrade B, large cohorts. Established.In large observational cohorts the top VO₂max quartile has about 4 to 5 times lower all-cause mortality than the bottom, and nothing pharmacological on this list comes close.
  • RentosertibGrade C, post-hoc biomarker. Phase 3, for lung fibrosis.Six aging clocks moved in 42 lung-fibrosis patients over 12 weeks, a design that cannot separate slowed aging from a treated lung, and no healthy-volunteer or outcome data exist.
  • Senolytics (dasatinib, quercetin, fisetin)Grade C, small human studies. Phase 1/2.Small human studies show the drugs can be given, with off-target side effects, but no durable benefit in people has been shown.
  • Partial epigenetic reprogramming (ER-100)Grade D, animal data only. Phase 1, in the eye.A first-in-human safety trial in the eye has started, but every efficacy result so far comes from animals.
