Study Finds a Surprising Link Between Gut Microbes and Aging

Researchers at the University of Hawaiʻi at Mānoa found that gut microbiome patterns were linked to biological aging rates in 123 adults.

Using blood biomarkers, the study estimated that gut bacterial differences explained about 15% of the variation in aging pace.

Bifidobacterium adolescentis was associated with slower aging, while Succinivibrio dextrinosolvens was linked to faster aging.

Published in Scientific Reports, the findings suggest the microbiome could be a useful marker and future target for healthy-aging research, but not proof of causation.
