Longevity
Strong human evidenceUrolithin A
Helps cells clear out worn-out mitochondria.
How it works
A gut metabolite of ellagitannins that activates mitophagy — the recycling of damaged mitochondria — supporting mitochondrial renewal in muscle.
The evidence
Multiple randomized human trials with consistent, replicated results. In pets the effect is inferred from conserved biology and species-appropriate dosing.
What the evidence supports
Supports mitochondrial health and muscle function.
The studies behind it
The primary literature for this compound, with what each paper actually found.

- Rapamycin alternatives for aging dogs and cats: what's actually claimed, and what has evidence
If rapamycin isn't right for your animal, several supplements and one serious drug programme are sold as alternatives. Here's an honest ranking of what the evidence supports — and where it runs out.
- Do dog and cat longevity supplements work? A graded audit of the shelf
We went compound by compound through the ingredients sold as pet longevity supplements and graded each on honest evidence — including the ones with a beautiful mechanism and no outcome data. A field guide for the sceptical buyer.
- The longevity compounds, and how strong the evidence really is
An honest, compound-by-compound map of the pet-longevity literature — with a graded evidence badge and primary-source citations for every molecule, including the ones that disappoint.
- Urolithin A: the mitochondrial-renewal compound with real human trials
A gut metabolite of pomegranate became one of the few longevity ingredients with replicated randomized human data. Here's the mechanism, the trials, and the honesty line.
- Why one science base serves both dogs and cats
Aging and immune biology are largely conserved across mammals. Here's how we translate human and preclinical evidence into species-safe doses for pets — and where the translation gets careful.
