David Marcinek: Biologist



Muscle endurance can be improved, in older adults, without physical exercise, according to the results of a new clinical trial.  Scientists in the US and Switzerland say their research suggests supplementation with a gut metabolite, known as urolithin A, may counteract age-associated muscle decline.  This is significant as a potential intervention that could slow the onset of frailty in older people, and prolong healthspan.   

The study, sponsored by the Swiss life science company, Amazentis  (also sponsors of this podcast), was conduced at the University of Washington Medical Center and the Fred Hutchinson Cancer Research Center in Seattle.  It was designed to test the hypothesis that long-term supplementation with Mitopure, a highly pure, synthetic form of urolithin A, would improve mitochondrial function and muscle performance in older adults.   

In this Live Long and Master Aging (LLAMA) podcast interview, the study's principal investigator, Prof. David Marcinek, explains the findings and why he believes they could be especially beneficial for older people who are  unable to exercise.  We also delve into the importance of mitochondrial health and why the so-called powerhouses of our cells play such a pivotal role in our ability to thrive and enjoy a long life.
