- The question
- Is urolithin A safe and does it affect human muscle?
- Study design
- First-in-human randomized, placebo-controlled trial in healthy older adults (2019). [1]
- What they found
- Urolithin A was well tolerated and produced a molecular signature consistent with improved mitochondrial and cellular health in muscle. [1]
- Limitations
- Molecular markers, short duration, funded by the company that developed it.
- What this does not mean
- Better markers do not yet equal better strength or longevity.
