Story summary

A team of researchers from the University of Granada, the University of Almería, and Leiden University Medical Center linked Roseburia inulinivorans to enhanced muscle strength.
Higher levels of Roseburia inulinivorans correlated with improved muscle capabilities in young and older adults.
In mice, administering Roseburia strains produced a 30% increase in grip strength.
The findings suggest probiotic interventions against aging-related muscle deterioration, but mechanisms and long-term effects require further study.
