Urolithin A Looks Promising for Muscle and Mitochondria, But It's Early

Key Insight

This review suggests urolithin A may support muscle and mitochondrial health, but human proof is still early.


Urolithin A is made in your gut when you eat foods like pomegranates and walnuts. It works mainly by cleaning up and recycling your cells' power plants (mitochondria). Animal studies hint at benefits for muscles, heart, and brain. But human evidence so far is limited mostly to muscle function and short-term safety, and not everyone's gut can make it.
