Mitochondrial health

Strong human evidence

The mitophagy activator urolithin A is safe and induces a molecular signature of improved mitochondrial and cellular health in humans

Andreux P.A., Blanco-Bose W., Ryu D. et al. · Nature Metabolism, 2019

Species
Humans
Design
Randomized controlled trial
Sample
Sedentary older adults, 250–1000 mg

What it found

Oral urolithin A was safe across single and four-week repeated doses, was bioavailable in plasma, and shifted skeletal-muscle mitochondrial gene expression toward a healthier signature.

Why it matters

The first demonstration that mitophagy — the recycling of worn-out mitochondria — can be pharmacologically nudged in a living human by something you swallow.

How much weight this carries

Strong human evidence

Multiple randomized human trials with consistent, replicated results. In pets the effect is inferred from conserved biology and species-appropriate dosing.

Compounds in this study
