Probiotic supplement shows early promise against cognitive decline in trial

Provided the trial's participant pool

Eighty-seven older adults with early memory problems took a daily three-strain probiotic powder or a placebo for 24 weeks. The probiotic group scored better on a global dementia rating and on visuospatial tasks, and had lower blood levels of pTau181, a tau marker tied to Alzheimer's. Verbal memory and executive scores showed no significant difference.
