Urolithin A
Two trials. Side results up, main results flat.
Grade B: Some human proof
Small, early or mixed results in people.
The grade is for the use people talk about, not for every use. Filed under: Longevity.
How it works
A compound that gut bacteria make from substances in food.
How it was given in studies
By mouth. In the trials people swallowed it as a capsule, tablet, powder or drink.
This is what the studies did. It is not a how-to.
What studies saw
In 66 older adults, muscle endurance was better at 2 months. At 4 months, walking distance and muscle energy production were no better than placebo.
The trade-off
Staff from the company that makes it co-wrote both trials.
When it showed up, in studies
Muscle endurance up at 2 months in one trial. Walking distance no better than placebo at 4 months.
