Supplement showdown: which urolithin a formula works best?
NCT ID NCT07231848
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested four different versions of the dietary supplement Urolithin A (Mitopure) in 48 healthy adults to see how well each is absorbed by the body. Participants took a single dose after fasting, and blood samples were collected over time. The goal was to understand which formulation leads to higher levels of Urolithin A in the blood, which could inform better supplement design for muscle and mitochondrial health.
