The Claim

Urolithin A activates the AMPK signaling pathway and inhibits mTOR activity in cardiac tissue of HFpEF mice, leading to restoration of mitophagic flux and improved mitochondrial respiration.

Source: Urolithin A activates mitophagy via the AMPK–mTOR axis and modulates the gut–ceramide axis to ameliorate cardiac remodeling in HFpEF

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In mice with heart failure with preserved ejection fraction, urolithin A increases AMPK activity, reduces mTOR activity, restores mitophagy, and improves mitochondrial energy production in heart tissue.

See the scientific wording

Urolithin A activates the AMPK signaling pathway and inhibits mTOR activity in cardiac tissue of HFpEF mice, which is associated with restoration of mitophagic flux and improved mitochondrial respiration, suggesting a mechanistic link between urolithin A and enhanced mitochondrial quality control.

Why this might work

Urolithin A turns on a cellular energy sensor that shuts down a growth signal, which triggers the cleanup of damaged mitochondria. This cleanup improves the mitochondria's ability to produce energy, which helps the heart muscle relax and pump more efficiently.

  1. Study: Urolithin A activates mitophagy via the AMPK–mTOR axis and modulates the gut–ceramide axis to ameliorate cardiac remodeling in HFpEF

    In mice with a type of heart failure, a compound called urolithin A helped clean up damaged energy factories in heart cells by turning on a cellular energy alarm (AMPK) and turning off a growth signal (mTOR), which made the heart pump better.
